Pearson 365/367 Mechanic Shop / RV-10 max HP rating
« Last post by charlotte94 on August 14, 2019, 02:54:29 PM »
I am repowering Haka Le.  Can anyone tell me what is the max HP for the RV-10?  Also has anyone repowered with a 50hp and kept the RV-10?   My Mech wants to put in a Volvo-pentra D2-50 or 50 hp.  I tried calling walter but they are closed for a few days       Thanks for any help out there

Pearson 365/367 Mechanic Shop / Re: Rear Oil Seal Replacement
« Last post by jpendoley on August 12, 2019, 12:49:04 PM »
The honest truth is, i am not sure. I don't think the rear seal is leaking any longer, but I do think its leaking from the front of the engine-possibly the front seal.  Can't really see exactly where it is leaking from-but the remaining leak seems upstream of the rear main. I am contemplating taking the whole front apart-as well as the front seal. Then again, it might be the oil pan itsself-which would be almost impossible to do in place.  Anybody have a great way to remove a westerbeke/perkins? Thinking this would be a good winter project

Pearson 365/367 Mechanic Shop / Metric oil filter?

Have a Westerbeke W44.  Does it take a metric spin-on oil filter?  If so, what is the correct filter P/N?

I took mine apart. The cooler is just a tube that the oil gets flung on. If you don't have water in the oil, it's fine. There is no maintenance.

OK, thanks Leo II.  As the 365 I have is new to me, I may pull the cooler section off and have a look to see its condition.  Just did an oil change on the drive... the oil appeared dark with no milkiness seen.  Cheers!

Oh excellent, thank you so much...

I can see the socket in the cabin roof for the stbd bulkhead, I sorta wondered how that might look
In the plan it looks like there would be a remnant of the shower some 6 to 8" deep suitable for a wet locker

I think the revised plan with the engine in situ and the cabinets a fair bit larger might keep me happier
a sh*tload less effort too

Mine does not, I believe the cooling is just a tube the raw water passes through ant the gear oil gets flung onto, not sure how they would get a zinc into that. I managed to avoid photography of that when I disassembled mine.

  Does the V-drive cooling section have an anode?  I can't find a plug in the casting for one.  The Walter exploded view drawing is unclear.

I have a Universal Diesel and thread size on its heat exchanger annode (that's coolant heat exchanger, not oil cooler/exchanger) is 1/4 pipe thread (NPTF).  If you are talking about the coolant heat exchanger, it is marinized part; therefore, it will likely be NPTF (tapered pipe threads) not metric or British.  It could be BSP that is close to 1/4 pip thread, so watch out for thread mismatch the thread OD  and pitch are close.
