Re: Yanmar Repower or ?!?

Maybe I take a month off and try to do it myself...

repower with beta and do it yourself in your slip.
read a book: how to install a new diesel engine by peter cumberlidge

in the end, the only labor i paid for was for the shaft alignment... why not

Re: Yanmar Repower or ?!?

I'm in the middle of a major overhaul of my Yanmar 3gm30F with only 1100 hours on it. Yes I always had regular service done on it too. Looks like a broken ring or two. With the price of Yanmar parts and how much of a pain it is to get parts on the west coast, and how few hours many folks are getting on some of them, I really can't recommend them. Just not worth it.

Sorry you have problems with your engine.

I'm running mid-70s Yanmar 2QM15s (raw water cooled) in both of my boats.

One is the original engine installed 35 years ago with undetermined hours because I am not the original owner and he didn't keep an engine log. I used it hard in the PNW (not a lot of sailing wind in the summer in the middle and south sound. The head has never been off of it. Routine maintenance and the typical exhaust elbow/hoses/belts/water pump impeller replacement and replaced the fuel injection pump due to erratic operation (my fault because the engine was not used for an extended period on one occasion and the rack rusted). But thousands of hours.

The other is an engine that was removed from a hard-used boat after overheating. It had a slightly warped head and the exhaust manifold was plugged with deposits. Had the head milled and mechanically and chemically cleaned the exhaust manifold. Replaced the exhaust elbow/hoses/belts/water pump impeller and did routine maintenance and replaced the alternator which was not working. Also has thousands of hours on it.

I really like these engines. I wish I had 3 cylinder engines for added power and reduced vibration but these Yanmars are simple and rugged and reliable and I know them really well. My only concern is that major parts are becoming very difficult to source due to their age.

But...if I had to re-engine I would look really hard at the Beta engines.

I went with Beta. Painful at first $$ but now I'm loving it.
