Sailing Boat Raw Water Pump Rebuild (Volvo Penta D2 55)

This is NOT a how to video, although I do attempt to strip and totally rebuild a Volvo Penta D2-55 raw water pump, after it started to fail at the end of last years sailing season.
If you would actually like to watch a channel where someone genuinely knows what they're talking about on issues mechanical, then be sure to check out the super helpful sailing channel 'SV Impavidus', here: kzbin.info/door/zHQmOL_aZx9qMSeSHTUMaQ They make sure valuable videos that I truly hope they get a little subscriber boost for their efforts!
If you like to know where we purchased all of our engine parts from, we use a company called www.parts4engines.com and they are very speedy (in the UK at least) and seem very competitively priced.

4). One of the ways which we're paying for this lifestyle (as well as working during the winter) is up-cycling old running rigging into dog leads and collars which you can check out here: www.cadoha.com/etsy-shop
We hope you're all starting to emerge from this strange time we've just been through, and fingers crossed the summer is kinder to us all than the winter was.
All the best.

Nice work. It's great you show ALL the parts going in/out in the specific order, assuming no knowledge, as others do. Our pump had a seized and rusted bearing, lipseal and circlip requiring "destructive" removal. The Volvo diagram is not totally intuitive so this was the best video for dissambly and reassembly. Thank-you.

Hey brother, when trying to work hoses on/off tight fittings, employ a heat gun for s few moments. This softens the hose without causing damage such as hard twists/turns/yanks or screwdriver prying can.

So in non marine applications of lock tight you want to only put 1 dot on the threads of the bolt/screw as it will spread it self as you are tightening up, more that a single dot can mean that you won't get it off. Normally it will say on the specific brand of lock tight instructions, just and FYI. looks like you did a smashing job. and valve clearances is done with a set of hardened steel feeler gauges, you can often find the expected tolerances in the workshop manual or online. I love that you approach this from a I can do it and that come with us on the journey, not a let me teach you perspective. That is how I am all the time also. so great job. :)

[@philgray1023]

I used this super strength Locktite for my traveler bolts. The kind that is listed as "cannot be undone". Feeling confident I told the commercial system plumber next door. He said " no such thing" just over-tighten first and it comes undone. I just wish he hadn't told me that. Now I worry about those bolts letting go.

Skip to around 8 minutes. He goes through some good tricks and common sense steps while troubleshooting the problem. I hope it’s as helpful for you and your knowledge base as a sailor as it has been for me😁. Since fixing mine it has gone from spurting out a dribble of water to a regular full gushing of water so I could not be happier!

[@grahamlongley8298]

I swopped the plate screws for stainless socket headed bolts. This means that I could use a short "T" handled allen key to undo them. In a rough sea, when I had an impellor go, it was easy to take the plate off& refit it. The allen key also holds the little bolts nice for locating in the holes so none drop in the bilge. I carry the key & a spare impellor in the engine bay because one year I lost 4 impellors then none for 3 years !!!

Heat is your friend regarding removing the raw water pump pipe.

[@Sailingengineer74]

Nice work with the seawaterpump! Seems you have the traditional "gardenhose" as seawaterhose connecting pump to filter and bottomvalve intake. Would kindly recommend to replace these hoses with proper Marine hardwalled rubberhose. If the engine for some reason gets hot, the gardenhose could melt and sink the boat. Or the plastic hose looses shape letting no water through. Overheating the waterpump by accidental dryrunning could be enough... Unfortunately these gardenhoses are very commonly used on boats.

Well done, good job, how many run hours has your engine got ? I also have a D2-55a with 1500hrs, so far no water pump problems. But I do have some tips for you. Check or fit the new exhaust elbow asap, as the water inlets get blocked. Really they should be checked as part of routine maintenance. Just in case fit a Temperature alarm in the exhaust hose, there is cheap on on the market that works well. Our heat exchanger developed a hole just in front of the elbow in the dry area nearly gassing us. Some sort of splash-back from the elbow when it got partially blocked. The repair bill was over £4k. I fitted a semi auto flushing system so no seawater sits in the system and rots it. Volvo do one as an optional extra. Fit a strainer down stream of the water pump, we had temperature problems for ages due to bits of rubber blocking the heat exchanger inlet left by the previous owner, it went unnoticed by 2 surveyors but that's another story. If/when the impeller starts to fail it can be some time before you notice by which time you will have bits in your inlet.

[@CadohaAdventures]

We’ve just bought a new exhaust elbow and it’s actually just been fitted too, so that’s one less job. That hole in the heat exchanger sounds horrible, I’ll be sure to take a close look at ours next winter and I love the tip about the strainer, much better to catch bits of rubber in that then get them stuck in the heat exchanger!! That’s so much for taking the time to share your wisdom with us!! 😁😁😁⛵️

@@CadohaAdventures Forgot to mention the clue to the heat exchanger blowing a hole is external corrosion at the bottom of the exchanger just before the join to the elbow.
