How to maintain a yacht/sail boat engine cooling system, including replacing the raw water impeller.

[@EnterpriseRacing]

Excellent video. I'd love to see another of you maintaining the freshwater system -- draining the antifreeze, cleaning the exchanger, o-rings, and refilling antifreeze.

[@danielbeetsma6118]

You have a talent for concise and crystal clear explanations. No further questions your honor - thanks a ton. We got this ;-)

[@rbukh]

Just wanted to comment on how nice I thought your video was. Your tutorial and your hands on explanation were wonderful. I appreciate your effort.

[@richardf3849]

Great video! I'm repowering with a Beta Marine and I was concerned with how to maintain them. This was very helpful!

[@darrylstein187]

Most informative video about boat maintenance. Subscribed. Im going to buy a sailboat in a year or two and preparing now. Thanks for the instructions!!

[@stephenberry6755]

You're the best. Clear, communicative, well lit and well shot. Many thanks.

[@andrewpowell3932]

Very clear, thorough explanation.. Thank you.

[@stephenpimley5619]

Excellent video - clear, well-paced delivery - thank you!

[@billfleet0]

Extremely useful vid. Everything explained well and shown completely. Best I've seen on small marine diesel cooling system.

[@AthelstanEngland]

Thanks for this. What a great engine bay to work on!

[@timothyhurst1085]

so helpful this video- I have a beta 25 in my boat. great video.

[@mikestanovich1414]

If all engines had such easy access as this one, life would be bliss.......

[@steadmanuhlich6734]

Very good demo. Good narration, clear visuals.

[@gerardwall8847]

Hello and thanks so much for a very helpful vlog. Just this week I was bringing my boat back to the mooring and noticed some steam issuing from the exhaust. Your sequence of checks will help me determine (hopefully) where the problem lies - either in the sea water intake (blocked?), strainer or pump (impeller). Regards Gerard

[@johnyenglish9393]

Excellent video. Well presented, cheers

[@dreameroftheday.8381]

Excellent thx, given me confidence and knowledge on my Beta 16.👍

[@spelunkerd]

You gotta love the simplicity of these little engines. Yours looks great, happy sailing! I'm sub'd, and looking forward to more.

[@JoeBlowBlues]

Thanks for that great lesson. Really enjoyed the video. I now understand my cooling system and can replace my impeller properly, Cheers

[@christinekennedy8212]

Simple and brilliant. Thank you

[@berniedonoghue8923]

Great video! I would point out that the hose coming off the strainer is not pushed home and there is 3/8" of pipe exposed 12:37. That will be a very unhappy diesel if that hose pops off starving it of coolant. A 2 minute job to undo the clamp, push the hose home and retighten.

[@littlewhiteyachtmaintenanc4565]

Thanks hadn't noticed that, I suspect it been like that for a long time, since before I owned the boat, but looks like you've found another job for me.... not that the lists isn't long enough already!. :-)

[@berniedonoghue8923]

The likelihood of failure is low, but it's one of those things that weakens the overall system and takes nothing to fix. It's often another failure that taxes that weakness. Imagine a failing motor mount, engine vibrates more and then pop.(I have an active imagination.:-) )

[@littlewhiteyachtmaintenanc4565]

Interestingly I've just replaced the engine mounts lol

[@mariotarsitano3692]

Your videos are amazing I really like your diagrams, I hope you do a video explaining fuel systems.

[@TheRebelOne.]

Fantastic presentation. Simple, educational, well delivered. Checking out your other presentations now. Thankyou. ⛵⚓👍

[@michaelrandold4656]

Ah thanks sir, for explaining this in a easy to grasp manner. ::cheers mate::

[@Mihalyofficial]

Great vid thanks, what does the sacrificial anode do exactly?

[@RumorHazi]

Loved the video! Very informative!

[@Kit2Canada]

Superb and timelessly relevant!

[@SkippySailor]

Hi, quick question: You mentioned @11:55 that the jubilee clamps have to fit well. In the event of the fittings breaking off, wouldn't it just be a matter to turn the seacock closed? Or were you referring when under-way?

[@Kit2Canada]

You know Murphy’s Law - well I bought a former charter boat as it was a “deal” (never again). One of the clamps on the bilge-pump had corroded through and water was just bubbling around when I arrived on the boat for a quick check as I do each week. Stuff happens on boats and all you can do is mitigate

[@ztumtzum5508]

Would the boat not sink as per your diagramme at 8:54? I think the exhaust should vent above the waterline.

[@littlewhiteyachtmaintenanc4565]

Yes, exhaust should have been drawn above the water line. Although it is not uncommon for the outlet to duck under the water on a sail boat, the positive pressure of the exhaust preventing water entering the exhaust pipe.

[@PittwaterMowingAustralia]

Great video Thanks for sharing Very informative

[@alferedfarjam8577]

After a while, when it gets hot, the water comes out a little and it is hot. Is the problem with the pump or is the valve damaged? Is the cylinder head gasket damaged?

[@voltairegoethe]

thank you - thorough/clear/concise question - is the strainer [to be most effective] mounted just below the water line?

[@littlewhiteyachtmaintenanc4565]

The water strainer is best fitted above the waterline, so no water can enter the boat when the seacock is not closed while opening the filter.

[@littlewhiteyachtmaintenanc4565]

Thanks for your feedback!

[@andreaspaul9138]

Спасибо. Норошое и понятное видео!

[@alexbilenkin3418]

diesel looks like Kubota D1105, I did not know about that sacrificial plug, will check it, thanks a lot.

[@littlewhiteyachtmaintenanc4565]

Thinks they are the same engine, at least parts often appear interchangeable.

[@alexbilenkin3418]

You r right, Beta Marine retrofits Kubota , B 30=D1105. If its not a problem, can You tell, where to order plug, Iam not good with tread, my friend told me , that plug is 1/2in, 18TPI, thanks.

[@littlewhiteyachtmaintenanc4565]

Do you mean the Annode (plug)?

[@littlewhiteyachtmaintenanc4565]

ah I ordered mine form the states i've the details somewhere i'll dig them out!

[@littlewhiteyachtmaintenanc4565]

So its a 1/4 NPT x 1-3/4" I got mine form BoatZincs.com

[@comicsandbeers519]

Top notch video 👍😊

[@brianlaird5355]

Nice video, When you lifted the basket out at 17:50 it looked like a piece of wire was caught in it. Was this something brought in from the outside?

[@littlewhiteyachtmaintenanc4565]

Good spot Brian.. it was just a bit of twiggy vegetation.

[@philipkenneth24]

Good video. Ever replaced the exhaust elbow gasket? I have some issues getting the bolts out, 1 broken head and 1 seized😬 on my beta 14.

[@littlewhiteyachtmaintenanc4565]

No sorry mate I've never removed the exhaust elbow. I'd imagine that a combination of the wet exhaust and heat may well seize the bolts in this area. As with all seized bolts, heat and penetrating oil often helps.

[@lazydays7470]

You might consider running the engine to full temperature which may reduce the friction on the bolts as the metal around the bolt expands slightly. The bolts will also expand but it may be less and also the heat may break the friction lock the metal has on the bolts. You may want to apply some additional heat with a propane torch. Be very careful using a torch in that area due to flammables close by. Keep a large fire extinguisher close by. If this works then once the bolts are out and the elbow is removed you can continue while the engine is hot and remove the bolt with the missing head using a small pipe wrench.

[@daviddawson9333]

Was the cleaning of the corrosion (fast frame) on the raw water pump just done with sandpaper?

[@PaulusPHM]

Still very current and educational

[@OfficialUSKRprogram]

I can't believe these have so little views. Man 2017 has seen an explosion in sailing channels.

[@littlewhiteyachtmaintenanc4565]

Thanks for the positive feedback.

[@d3891]

I agree well explained detailed video would love to see more beta engine videos..well done!

[@southronspirit]

great video ,

[@littlewhiteyachtmaintenanc4565]

Thanks... nice to get some feedback!

[@sweetbrandigirl]

Yeah Ditto Thanks for doing these !

[@complaintdesk4626]

Where is the coolant drain plug?

[@kiwiwifi]

Funny thing.. The Beta Marine service manuals make absolely NO mention of a thermostat. Its like it doesn't exist. So strange.

[@d3891]

great video!

[@FrancisRichard1957]

d3891 hi how does thermostat work...where is it on a beta...? Enjoyed the vid but it does not answer that question!

[@wndhl4347]

Brilliant. Thankyou mate

[@BeunenmetBoten]

Nice video! But we think you forgot one thing: the thermostat. Both in the schedule and in maintenance. But still a good video though!

[@koos5548]

In depth video, but please get the details right first. Just a few items that caught my i at first glance Seacock shows signs of dezincification (green), meaning it is brass instead bronze or cr messing and can tear off at any moment. Basically making your vessel a timebomb to sink. Adding a backinplate would be even better. Hose clamps should be of te closed type. These are prone to tearing. Hose on the strainer is not pushed all the way up on the connector. I saw another hose connect to a copper tube without a connector.

[@littlewhiteyachtmaintenanc4565]

Thanks for your feedback, as with any 30 year old boat many things are not prefect. I've not mentioned dezincification in the video as the field is complex and at little contentious. But I'd agree with you that diligence of inspection of seacock and through hull fittings is important. As for hose clamps.. personally I prefer the open type hose clamps, I think they slip less, than the closed type. But as with anything quality is the important thing here. My strainer hose has now been pushed home, good spot!

[@yeonhoian]

Thank you Great help ! Show me more

[@nigelbutler5040]

He forgot the electrical system, he forgot the mechanical drive system. He forgot the exhaust system. He forgot the air inlet system, he forgot hm just about everything..

[@NeverEnoughPyro40]

Why don’t you try reading the title of the video again smart ass, This video was about maintaining the cooling system! You were so quick to write a smart ass comment that you miss read the title of the video, Next time take an extra 30 seconds and read the title of the video so you don’t embarrass yourself again!

[@mongsmcmonagle]

The title says cooling and the intro says cooling

[@djkillachris]

Check the coolant. It goes bad

[@annoyingbstard9407]

That’s not right. The “tank” of the heat exchanger is the fresh water and the “raw” water is pumped through the bundle of tubes.

[@michaelguthrie2344]

First write your script they drop your Ums & Ars.

[@somyrab]

Painfull

[@cl60cruzer]

thumbs down,weak sound

[@littlewhiteyachtmaintenanc4565]

Thanks for the feedback, I'll try and improve with my next video.

[@michaelbower4245]

Sound was fine for me. No problems
