[QUOTE=KnotDoneYet;18251]For those that have replaced their M35B, what was the cost? It sounds like once you are in there that you should probably get the transmission also.

I will have this done as it's way beyond my capabilities.[/QUOTE]

Your tag line suggests you do not yet have a C36 yet. It's a great boat, but there are a lot of C36 boats around. With so many options of good boats, I don't think anybody should consider buying a C36 with the idea of replacing the engine. As a matter of fact, I don't think you should accept anyone giving you a free boat if it needs an engine.

This presumes that you want to buy a boat to go sailing. If you want to buy a boat because you like hanging around marina yards and dealing with guys who muck with engines all day, go for it. In general mucking around with boats is a good thing, but the sailing part is much more fun than the marina part.

Greg,

I removed and overhauled my engine on my C36 MK1, not by choice. A also upgraded my last boat from gas to a Yanmar diesel. Yes it is a chore but, if I had a chance to purchase a MKII boat discounted to the point of covering the cost of repowering, I would be all over it. It eliminates one of the major variables in boat ownership to start with a fresh engine. Upgrading to a more powerfull Yanmar would add value and be a real plus.

I never replaced my engine but a friend with a C34 replaced his with a Yanmar. Cost was $14K. The stringers needed altering and he did that so I imagine the whole job being done by a pro would be around the $17K you mentioned, depending on where you are located.

Diesel engines are "bulletproof" and a rough looking engine does not necessitate its removal. A reasonably well maintained Universal M35 should get at least 5000 hours and a well maintained unit should get a lot more. Diesel engines are heavily built and unless the block is cracked or there is other catastrophic damage, the engine can be rebuilt for a lot less than a $14,000 replacement.

I can tell you this, I have replaced the the 25XP engine in my 1984 hull two years after purchase. I spent much of the time prior to that "chasing" problems with over heating, electric issues and generally just not knowing how it had been treated prior to me coming along. I called Catalina and was able to purchase a new old stock crate motor 25XPB that fit right in with very little modification. What was needed was time and lots of "little parts" to finish the job. The piece of mind I got from doing the job myself and having a brand spanking new motor is liberating to say the least. The cost of the motor from Catalina was 5k, very cheep but when I called they only had three left and this was two years ago, not sure whats left if anything at this point. I know the beta marine engines are simular to ours from the research I have done but the cost is closer to 9k for those motors. Rebuilding is a good option if there are no major issues with the block or other major parts and as suggested a lot cheaper as well. If you need help or have questions let me know, after the time I spent I am pretty sure I have the answers...:)
