[@ronkoenig4145]

Very well presented and timely as I am going to inspect a 39 year old 27 foot boat for purchase which has a saildrive unit. I now have a few more things to look for and a few more questions to ask of the owner. While I most likely would not try a renovation, as you have done, I now can appreciate the work required if I have it done by a ship engineering company. Thanks again.

[@bigglesone7673]

I did my saildrive 7 years ago so our Bavaria 36 is due a change again this year. Like Chris I am a retired RAF aircraft engineer and well taught in the useful skills for this job (although my experience of aircraft is probably a couple of generations before Chris's!) But this video is a useful reminder of the sequence and pitfalls of the operation. The Bavaria does not have such good access as his boat but I was able to remove our engine completely which made life easier although it did involve disconnecting the engine entirely with the subsequent necessary reconnections and engine bleeding etc.

[@SailingBritaly]

Hi there, thank you for watching & commenting. I'm sure it will be a lot easier for you this next time round as you've already done the job once. I couldn't find any videos like this out there before I did ours, so I hope that this will be of value to other boat owners who like to do their own boat work. I personally believe that the trade training at Cosford (or Halton as I believe it was before) is amongst the best in the world. I have certainly never seen anything anywhere near as professional anywhere in the commercial world, despite working for a variety of oil & gas companies with vast budgets. Fair winds! Chris 👍

[@billgiles3261]

Biggles One I was at Halton back in 1960 aged 15 on a 3-year apprenticeship. I worked on a whole host of aircraft, now all obsolete! I took up sailing in Gib where we lived next to the Sailing Club on the harbour (now filled in). As you say the RAF Training was second to none and set me up with long lasting skills which I am using sixty years on. Good luck with your project and hope that you and your young family have a great sailing adventure.

[@spelunkerd]

Another brilliant demonstration, thanks for those small details, and for including the locking wire oversight. When you considered applying heat to the aluminum housing to get the sea cock off, I remembered a few disasters I've had doing automotive repair through the years. Heat and aluminum don't go so well, I've stripped out aluminum threads frozen to steel bolts more than once.

[@SailingBritaly]

Hi there, that is a great compliment coming from you, thank you! I was being careful with the Aluminium as it is delicate. If things had gone wrong a helicoil could have been an option, but I had enough on my plate already whilst filming this, so fortunately that wasn't needed. :-) Comments on KZbin are fantastic as it give the world a chance to peer review videos like this for the benefit of everyone, so thank you for taking the time to share your opinion. Cheers, Chris 👍

[@patricklindahl868]

Very nice work! I have been doing this a couple of times, when I was working in a small boat workshop in Gothenburg, Sweden. I saw some things that should be adressed sometimes in the future: 1) Control wires are brown = very old and often rusty inside the shield. They tend to break exactly in the middle of a maneuver. I would recommend new low friction wires. They are often black nowadays 2) When you have the shock absorbers loose, consider get a new pair. If they are 26 years old as well, the rubber often separates from the steel and then they do no good. 3) The fuel hose was reinforced plastic hose, that get extremely stiff by the diesel oil. It should be replaced by a oil resistent rubber hose, preferable of a type that don't generate static electricity. You have a very good engine, VP 2003, but unfortunately the spare parts are discontinued by Volvo Penta. So take good care of it, never overheat it and change the oil one time too often, it's never wrong to have clean oil, whatever the instruction manual or your boat neighbor says. At least once a year despite running time.

[@SailingBritaly]

Hi Patrick, thank you for watching and commenting with your intelligent observations. I was aware of the fuel hose before I bought the boat and at the time of filming this video I had already bought the replacement. A proper diesel-greade fuel hose has now been fitted (it's in one of our more recent videos). Thanks again for commenting, which helps any other viewers reading this, as well as us. Fair winds! Chris 👍 (plus Rossella & Emma 🙂)

[@cblandblueyonder]

Thank you very much for taking the time to do this. We are in the process of renewing the diaphragm on our Bavaria 35. I noticed that you seemed to have solid engine mounts with no rubber bushing - ours has the original, which are rubber, and presumably take some of the loadings. The rear hole, which you had to pack out, is still circular on ours, (despite a lot of use!), and I wondered if this might be related to the fact that the rubber mounts provides some give on ours, so there is less stress on that bolt hole.

[@SailingBritaly]

My pleasure! Our mounts do have rubber sections too, but my "stress test" was too much for the stbd one. The packing on the rear mount is still perfect. 🙏 Best regards, Chris 👍

Thank you!!! I am currently working up the courage to get into this job and I feel so much better after watching this excellent walk through. Again, thank you so much for making this video!

[@SailingBritaly]

You're very welcome Erik. Good luck with the job! 👍

[@antonynr]

Hi - I changed mine last year - used a winch to drag the engine forward, rather than levering it. A tip for next time (which I expect you will have forgotten about in 7 years) Set up a Spanish windlass between the keel and the saildrive before you start and tension it - this will keep the drive level as you move the engine forward and save you from using levers on mating faces!

[@SailingBritaly]

Hi Anthony, the mating faces were intact as I was being gentle whilst levering. As always, doing this a second time round would take half the time (or in my case less than a quarter of the time as I won't be filming it again!) I used a trucker's hitch from the keel to the saildrive in the latter part of the video to achieve the same end and it worked a treat. It literally took about 10 minutes to get the engine and drive engaged with no help from anyone. If I was to do this job again I would use the same tachnique to maintain the position of the saildrive whilst moving the engine forward by hand (In the end I found I could just manhandle it around wherever I wanted it). Cheers, Chris

[@simergr]

Great job you've done and you should be proud of your self. Only one thing for next time when you put back steel bolts under sea level always deep them in marine grade grease first so next time they will come off easily and reduces galvanic corrosion too. I have worked with outboards for some time professionally and instructions are clear about using grease to every bolt except those that are on the engine like head bolts. Greetings from Greece and thank you.

😂 Cheers Matthew! 👍

[@Bowman339]

A method to get the sail drive lined up to the housing is really long bolts. Then swap them out for the correct bolts as you line it up.

You are such an inspiration! Many thanks

[@SailingBritaly]

Thank you! Don't forget to subscribe 😉 Chris 👍

[@kdl0]

Your engine bed is a lot different than the newer ones, they don't have that deep gap behind the engine mount areas almost until you get to the flywheel. Also - do you think that adding permatex might change the shimming needs? That will add a tiny amount of length to the transmission.

[@mikecress3297]

Learned a lot, and got my Emma fix. I'm good!

[@SailingBritaly]

Thank you Mike! 👍

[@gimamotor]

Great job as you did it as first time, and great child!! Just to know... Volvo penta recall to put 15w40 oil in SD

[@moonshine3333]

I really am no engineer but remember helping my Dad put a gearbox back into a car and had a real problem getting the gearbox spline to mate into the flywheel. If that makes sense did you get lucky because if the shaft didn’t align I’m not sure what you’d do. Turn the engine over by hand? You really are very talented 👍

[@SailingBritaly]

Hi there, the main problem with this (as was seen on removal where it took a while to split the saildrive and engine) is keeping the saidrive and engine aligned - the saildrive can move around quite a lot and if it's not supported then it tends to drop down at the fwd end, this small angle of misalignment then makes it difficult for the splines to disengage (or engage on the way back in). When I was mating up the two the saildrive was held steady and at the correct height by the lines and support outside the boat, so as I lifted the engine and moved it backwards the splines were aligned. There is very little rotational resistance in the transmission and I believe the splined saildrive input shaft could be rotated by hand if necessary, however I believe that anyone who has trouble getting the engine and saildrive to mate is far more likely to be dealing with angular misalignment as outlined above, rather than rotational misalignment of the splines. Thank you! Chris 👍

[@dapman2007]

Chris, Just like to add my gratitude to the rest. A very real demonstration of work on a boat in a confined space. I'm about to embark on this task and there is a lot of very useful stuff here. Thank you

[@Etvi]

Thank you for a very useful video. Only now I realized that it seemed as your prop anode was painted over with the antifoul. Hence, the anode was cut off from the water and the propeller got corroded. The kind of things that do not appear obvious until you learn by experience.

[@sxmNice]

Very interesting, thanks. BTW, I changed this seal on a friend's boat. We used the main sheet hoist to lift the engine (thru the companionway). I think its an interesting alternative to the use of wedges.

[@SailingBritaly]

Hi Georges, that was my first choice too but the geometry was wrong on our boat and the engine would have come too far forwards (without taking the woodwork apart). This was easy enough, it probably looks harder in the video than it was in real life. Cheers, Chris

[@kamilkutlay]

thank you very much for these and wish happy long years for little cute emma

[@jeffbiesenberger749]

Great video and thank you for posting. While you are at it may I advise you change your brass screens in your air intake silencer on your Volvo. Over 20 years ours fatigued and then got sucked into the #1 cylinder requiring us to remove the head. We replaced with a K&N air filter with foam interior to avoid headache again.

[@SailingBritaly]

You’re very welcome. Thank you for your advice regarding the air intake silencer - we can all learn from each other. Chris 👍

[@johninerie9251]

Excellent job - I, like you, prefer to do things myself - I think it is unlikely that another person doing this in a shop would have spent as must time and care making sure everything was throughly cleaned before reinstalling. Yep it will take you twice if not three times as long doing it yourself but it’s worth it - and these videos are an immense help for the next DIY’er to know what they are getting into before starting a job and the shop manual never has all the information you need when the parts aren’t new and pristine. Keep up the good work!

Thank you John! 🙂

[@myrlover]

Thanks for the great video, helped me a lot when putting together the parts after changing the seal rings! However, when I pressed the roller bearing ring in place like you have done at 1:03:10, the shims under the ring has some millimeters of space to move around. When you knocked the bearing housing home with a hammer at 1:04:47, you actually moved the roller bearing ring some more millimeters into the bearing housing so that it squeezes the shims, like it should. If you would remove the shaft and bearing housing again, you would see that there is some millimeters between the roller bearing ring and the edge of the bearing housing. If you removed the shaft and bearing housing again, you could easily put it back without using a hammer. I'm not trying to point at any errors, because you did nothing wrong, however, I spent some hours trying to figure out if I lost some shims and hope this comment will save someone else's time.

[@fopsmit5517]

Hi Chris, not sure if possible on your boat but we put a tackle on our boom to lift the engine out of her bay. The tackle takes the weight and you can concentrate on positioning. might be an option for future engine/saildrive jobs.

[@SailingBritaly]

Hi there, yes that was the first thing I looked at but on our boat the lifting point would have pulled the engine forward about a metre, so this wasn't an option for us. Levers and manhandling worked ok though. Cheers, Chris

It is a silver-grade anti-seize paste that is commonly used to prevent galvanic corrosion and seizing between these types of metals." Thanks for watching & commenting, Chris 👍

[@SimonMcArley]

Interesting. I have a mostly the same sail drive unit and my mechanic has recommended ditching the raw water inlet completely and fitting an alternate thru hull at a more accessible position. The reason is mostly those mussels you found way up inside the unit. Apparently fine while the boat is in the water but when you haul out they die. When the boat goes back in the remains migrate and cause a nasty surprise as you head off on your passage with your nice clean bottom. So good plan to fit the backup supply.

[@SailingBritaly]

Hi Simon, yes I was surprised to see such large mussels up so high, they obviously enter when tiny and then grow in-situ! We are happy to have the backup cooling water supply. It's like a cooling water insurance policy :-) Fair winds! Chris

[@digitalfantazia3953]

Another great video Chris. I havent got a saildrive as I am on outboards and propshafts but if I did I would be watching your video. :) for tips. A good comprehensive chapter. Had a very worrying incident once with a propshaft. Both jibsheets fell over each side of boat while underway because our charter co forgot to put figure of 8 knots on bitter end of sheets after last hire and we overlooked it...duh.... Anyway upshot was (sods law) that they both got wrapped round prop and ripped the gearbox mounting plate off the engine face, causing the prop shaft to slid down inside the outer shaft tube a few inches. Not nice at 8pm at night when the wind drops in the Med. Thankfully it didnt bend the shaft or slide and drop into the med and fill the boat and leak...!!!!. No idea what impact it would have on a saildrive leg in the bottom of boat..... so worth knowing from our mistake. Always put a stop knot in end of jib sheets if they go far enough to back of boat to be near the prop. If your ever up our way send me a ping. Fair winds David

[@PaulusPHM]

Cool video, reminds me of my days in aviation training back in 1970's

[@SailingBritaly]

Thank you :-)

[@dangonzales2896]

I saw another fellow deal with having to weld a broken engine mount. I believe that they would not break as often if the plates were drilled to accommodate the big bolt before it is welded.

[@SailingBritaly]

I reckon you're right Dan. The design is adequate, but it could definitely be improved. I guess if it lasted 26 years then isn't bad going really, but I'm sure a simple tweak of the design of the mount could make it last the life of the engine. Cheers, Chris 👍

[@alainbourjolly8245]

merci pour cette video instructive; on se sent un peu plus preparé a changer le joint par ns meme; cheers

[@BigBadLoneWolf]

Yes, that was the correct way to wire lock so that if a bolt starts to come loose, it is tensioning the wire at the same time. this way the bolt will stay put

Yow! He is going to move the whole engine to replace the sail drive seal! In other news, the only sail drive that you can remove and replace the sail drive oil from while the boat is in the water is BetaMarine. Their biggest engine / saildrive is the Betamarine SD 60, which has 57 horsepower. It's based on a Kubota diesel which they have marinized.

are u using copper based antifoul on the leg ? great vid , not one swear word , amazing

[@SailingBritaly]

Hi Bill, it's a standard antifoul with copper oxide, but we have a protective later of epoxy first so it isn't in contact with the Aluminium, and the wastage on the anode will be monitored carefully so that it can be changed as often as necessary to ensure that the leg is protected (I made sure there was extremely low resistance between the anode and the leg upon installation). There will be no swearing on this channel - there may be in real life, but we will always edit this out of our videos as we want to be family-friendly! Fair winds, Chris, Rossella & Emma 😊

Excellent video.

[@SailingBritaly]

Thank you Paul. :-)

[@ralph9987]

Bloody awesome mate. What was of the prop coating? Keep up the good work!

[@Medwaydroneexploration]

Great video guys, Even though i'll likely never change a sail drive diaphragm in my life i still found it interesting all the way through, gives me an idea how boats work :) Great to see my Drone footage still coming in handy too :) Emma's laugh is so funny :) Catch up soon Garreth

[@SailingBritaly]

Hi Garreth! Never say never, you might own a boat with a saildrive one day... Your drone footage is excellent mate! I look forward to seeing you again soon. Cheers, Chris 👍

How did the CT1 work for the outer boot?

[@josipbrezac5824]

[@SailingBritaly]

Thank you :-)

[@akkemik]

Oh man you are awesome and i tired when i was watching. Now i'm start to think how can i do with mine! well done! You got me and will check all your vlogs. best

[@SailingBritaly]

Welcome aboard Murat 😊

[@waynejenkins3607]

Brilliant job, M8. I've always wondered how the seal works on a sail drive. One thing, Is there any vibration dampening on the forwrd engine mounts?

[@SailingBritaly]

Cheers Wayne, there is a vibration dampening rubber section between the engine and fwd engine mounts. So the stud which was welded to the base of the engine mount is protected from fatigue by this rubber. 👍

[@MortenDallDarmer]

How did the CT1 hold up?

[@aleksanderkastelic2214]

Bravo very good knowledge...

[@CadohaAdventures]

Awesome video, really easy to follow along. 👌🏻

[@SailingBritaly]

Thank you Carly & Dom, you guys have a great channel and will do very well indeed! Chris 👍

[@CadohaAdventures]

Sailing Britaly well as long as our family and friends can follow our travels through the videos and not get too bored watching, that'll do, anything else is a bonus. We too have a sail drive and I have to say, judging how pristine your old one looked, I'm not going to panic too much that ours is dated 2010, although if I do find the nerve to tackle job myself, I'll be sure to bung you £50 to say thanks for the tutorial, and you can hold me to that 😁🍹

[@asdwat111]

Very nice work, especially good documentation! We want to do the same thing on our boat this winter and change the platic valve as well. Can you tell us the diameter of the thread in the aluminium gear part? Would be a great help for preparation! Also there are boats like ours, where the saildrive goes throught a very needly hole in the hull without any rubber seal at the bottom, so we can´t get the bottom part of the saildrive out of the hull that easy. I think the bottom part can in this case stay in the boat, we have only lift it enought to reach the screws. Thank you for the great content! Greetings from germany!

[@SailingBritaly]

Hi Tom, danke for the feedback! :-) The seacock thread is 1/2" and we bought ours here: www.yachtboatparts.com/volvo-penta-saildrive-sea-cock-seacock-bronzedzr-7204-p.asp I'm not sure I understand what you mean about the saildrive on your boat: if you want to replace the saildrive diaphragm seal then you need to split the leg. Let me know if I can be of further assistance when you do the job. 😉 Cheers, Chris 👍

[@asdwat111]

Thanks a lot for your help! At first I want to buy theese new Valve and fittings here in germany, but now we see the cheep prices you sem to get in england. Do you know a shop where we can get also t-parts and other fittings? With our installation on the boat, after splitting the saildrive leg, the bottom part will still stay in the hull, because the gearbox down at the propeller ist to wide to fit throght the hole in the hull. So my plan is to lift the saildrive up as much as possible, fix it in this position an then seperate the two leg parts in the boat. In this video you can see the small hole in the hull kzbin.info/www/bejne/i2SVqauPZsp5jpo Cheers!

[@SailingBritaly]

Hi Tom, that's an unusual setup which makes me wonder how they got the leg in there in the first place! (There must have been a larger opening which has since been filled and faired) ASAP supplies were good for us www.asap-supplies.com/ but I believe SVB can be good for certain things www.svb.de (and expensive for others) We always shop around whenever we buy things because prices can vary a lot and different suppliers can often be competitive for different things. Happy fixing! Chris 👍

[@asdwat111]

Hi, @@SailingBritaly , I think the got the leg in and laminate a plate around the bottom hole to get it very smooth. Thank you a lot for your help, we love your project!

Good job! Very didatic and profissional Regards from Brazil

[@janvanarendonk2848]

Hi guys! Great job! I’m planning to do the same job next spring. I have a question regarding the size of the seacock on the saildrive unit. It seems quite difficult to find the sizes of the required parts. Do you might have this info? I think it’s a 3/8 to 1/2 fitting with a 1/2 1/2 seacock. Tnx and keep up the good work!

[@SailingBritaly]

Hi Jan, my pleasure. We bought this: www . yachtboatparts . com/volvo-penta-saildrive-seacock-ball-valve--bronze-dzr-stainless-7204-p.asp (remove the spaces) and I'm very happy with it. Cheers, Chris
