Hello from USA-I just saw the video on the Pump rebuild (Ep. 17 and 18). Pump was not pumping water thru the heat exchanger and out the exhaust. Have cleared all the pipes and city water line does send water thru the raw water cooling system. Tomorrow we will strip the pump out to determine cause of pump not pumping. Let you know our progress in a day or two. Thank you very much for a very educational video. You, sir, are a very good instructor. Thanks again.
Thankyou for your post. I have the same engine and was having intermittent overheating issues. Your post has given me enough courage to attempt the task. My initial stumbling block was a frozen nut that locks the angled pipe coming from the engine block to the elbow. The one that you used a ring spanner to unlock. Took hours of patience and various methodology to unfreeze it. When I put everything back on again ( with new rubber ring seal - not O ring as you’ve mentioned ) there was a leak at the joint which I have managed to fix by putting an additional O ring into the joint. My elbow was just as corroded as yours. Boat is running cool now, thankyou again.
Hi Paul, thanks for the vote of confidence. We enjoy making these videos and hope they are of use the the "boating" community. Future topics to come include, cooling water pumps and folding propellers on test. Cheers!
We use to say at the race track, you don't know how far you can go until you go past it lol, I think you found the exhaust limit, I have seen stainless steel ones around
I like Mario Andretti's race track quote. "If everything seems under control, you're not going fast enough." Cant help but wonder if he ever tried down wind sailing with an out of control spinnaker? I'll report back how many years the standard cast-iron Volvo exhaust lasted. thanks for watching.
Very informative and possibly very helpful as my next task is to replace the exhaust elbow on my 2002. What material O-ring did you use for the pipe and is there a generic replacement for it available? And If my hose is stuck, I'll know what to do. ;)
Hi MB, the rubber o-ring is part of a Volvo Penta service kit. I would recommend using genuine parts due to the fine sealing tolerances required. Good luck, Rob
Hi, very useful video, n thanks for the post mortem! If there had not been a massive corrosion on the elbow, would you have had it cleaned and use it? or is it wiser to replace it in any case? If to clean, how? your suggestion would be? thanks in advance.
Hi, on the basis the exhaust elbow is the original and over 30 years old. I didn't even consider cleaning it. I had a mixer elbow failure on a previous boat , spraying salt water over the alternator and filling the bilge. Not a situation I wanted to repeat! Regarding cleaning solutions I'm sorry I can't help. Cheers!
Was there a restriction in the raw water output? Did that result in steam? I’m having what I believe to be a steam issue with a Volvo KAMD 300 and the exhaust elbow has been suggested, after I change the impeller and check the raw water strainer. Thanks
Hi Michael, I noticed the lumps of rust under the exhaust elbow first. It wasn't until I cut it in half that I realised the water gallery was blocked. You may well have the same problem with your KAMD 300! Thanks for watching. Rob
Good job. I just did the same, to check. But the elbow was in good shape so left it there. I have the same White smoke from the exhaust at 2000 - 2500 rpm. It is cause for corncern?
Hi Erik, it was a cold day when I made this video so white smoke would be expected. If you're concerned about your engine check out the thermostat operating parameters and exhaust temperature. Thanks for watching and happy sailing!
Thanks. It turns out my problem was in the intake of seawater. Blowing water back through the seawater filter solved it. This I discovered AFTER tearing apart and cleaning the entire cooling system to no avail.
What do you think that white smoke is? I have the same issue on the same engine. No loss of compression just that same smoke and with mine i have a tad bit of sheen of fuel or possible coolant. Not real noticeable, but enough to piss me off. I am thinking injectors because no loss of collant at all. I changed my elbow like you did. Thanks again Mate.
We're trying our engine on a different diesel this season. In the past we have always used the fuel dock 'red diesel'. This year we've filled up with shell V-power (white) Road diesel. It's twice the price however it has a cleaner additive to improve injector performance. Our engine is over 30 years old but runs and starts without problem. I'm keeping my fingers crossed a bit of chemical TLC will improve the white smoke issues.
Hello Sailing Aphrodite, good question where did the 'gunk' come from? Other boats I have owned had plastic fuel tanks and didn't seem to suffer with diesel bug problems. This Bavaria has a stainless steel tank. Although the tank is topped up with diesel after every trip, by the end of the sailing season I still experience a cup full of gunk in the bottom of the tank. Iv'e tried many makes of fuel additives each promising to alleviate diesel bug issues, none seem to work! To summarise, I put it down to condensation issues. Warm fuel returning via the spill pipe into a cold tank. For price of mind I'll continue cleaning the tank as a pre-season shakedown check! Thanks for watching!
Great video, really well put together and deals with a topic many boaters have to deal with. I have just done the same job with my Volvo Penta, I used a stainless exhaust elbow in the hope it may have a longer service life. It was interesting to see your dissection of the old exhaust elbow, I would hate to think what mine would have looked like! As an engineer you may be interested in or probably already aware of the issues with some of the sea cocks fitted to yachts and the brass becoming brittle over time - if not this is a starting point ruclips.net/video/8p0gysglfUU/видео.html . Thought it worth sharing since obviously you and the family spend a bit of time on the boat.
Hi Paul, thanks for your comments and yes sea cocks and skin fittings are part of our rolling service plan. We change them every seven years along with the Volvo Penta 'doughnut'. To make life easier I have made a skin fitting extractor. You raised a good point, stainless steel or cast iron exhaust elbow. I went with original manufactures specification, after all its lasted thirty years! Fair winds & following seas, Rob.
@@sailingwithus5743 I was about to ask the question how many years service had that elbow seen and found your answer. I'll need to take a look at mine as the boat is 35 years old.
Thanks for cutting off the elbow it made me see easier how it works ❤

Hi guys, thank you for the kind feedback it means a lot. Good luck with the fault finding, please let me know what you found?

Hi SYA, good to know the video was useful.
Nothing boring about that. Great to see the part cut in half. Looking forward to your future vids.👍🏻

Paul.

no boring, very informative!!! Thanks for that!
Hello sailors RPBLC thanks for the feedback!
This was very useful. Thanks much!
Thanks for leaving a comment. enjoy your boat!
Great video thank you. I have an MD5 single cyl that needs a lot of maintenance. (just purchased boat)
The MD range was a sturdy oil workhorse, they're getting long in the tooth. can you still get parts easily?
@@sailingwithus5743 Service parts are still available, which is good. They are an old workhorse.
Me tocó hacer algo parecido en mi motor Volvo 2002, y la verdad es que con el nuevo colector de escape el motor va mucho mejor. Un saludo!
Gracias por visualizar mi video. Espero que tengas una buena temporada navegando este año y que tu motor te cuide.
Muchas gracias!!! Igualmente!!!👍🏻
Helpful! Thank you

Hi Rob, thanks for the answer! haven't started the job yet, but I got a cooling and diesel pipe o-ring kit from parts4engines.

I'd be interested to hear your thoughts on why the bottom of your tank has all that gunk in it.

That elbow seems to be a design flaw on these engines as I have seen so many boats with the fault
Hi and thanks for your comment, inherent design fault or not I guess it needs treating as a service part. Thank you for watching.
