next question.
next project, can the brains trust please advise on replacement for this engine. Reliability and power are the only criteria.
Existing engine has been rebuilt over the years and is good but I am tooooooooo old to have snagging doubts, I want 100% in every area, boat Sigma 362, LH folding prop, huge battery bank.
thanks

Any Yanmar, Nanni, Beta, Volvo that will fit will be fine. I truly believe that there aren't many really bad modern diesels. Check the access points for servicing for your boat installation and price them up and take your pick.

Last time we bought new, I was suprised at how close all the prices became to each other after the bargaining was over.
 
100% in every area!

You are intending going sailing aren't you?

A well maintained engine fitted amongst well found and proven systems and ancilliaries is likely to be at least as good as anything you replace it with, once the chopping, changing and adapting has been done.

I wish you luck in finding your 100%. I thought I looked after my yacht well, but I fully expect some failure or other at some point in the season.

I find a healty armoury of 'workarounds' makes more sense than trying to acheive the impossible. Like you, I have a well looked after and reliable VP (2002). This didn't stop an overheat alarm caused by a strainer blocked by living creatures 1 month after launching (and checking). Only time this has happened in 7 seasons. Like you I sail in less congested waters so found this no problem at all to work around 'til the cause was identified and fixed.

Nice boat BTW. I love the look of the 362.
 
If you replace a VP with another VP, fitting should be straight forward. If you replace with another 'brand' you may incur a lot of adapting to get it to fit.

I was told once that most marine diesel engines are only marinised cement mixer engines. These are designed to run flat out day in day out.

The problem with our boat engines is that we, thinking we are doing the best for them, start them up way before we motor off, to warm them up, only run them at half revs and put the best synthetic oil in them when in fact cheap diesel oil is far better. All this is killing them. The engineer who pointed this out to me told me he sees more engines 'dead' as a result of owner kindness, glazed bores usually, than he does see genuinely knackered units.

Just a thought.
 
Cornwall, eh..

Why not give old Dave Llewelyn a bell, DL Marine in Truro. Best bet is to catch him on 07973 523 329.

There are some serious cracking good deals on Lombardini right now.
 
I think your main difficulty in fitting a replacement is that your volvo gearbox changes the angle of drive from horizontal in the engine to about 6 degrees downwards for the prop shaft. Most other engines and gearboxes in my experience go straight through and the engine itself is tilted backwards. There may or may not be room to do that in your present engine space. Almost certainly the engine beds will need modification and/or the use of special mountings.

Personally I think the volvo arrangement whilst claiming to be space saving is an attempt to persuade you to replace like with like.
 
I replaced my knackered 2003 with a new 2030 - Its a great engine but hidden costs were a new propshaft, new deep seas seal - The volvo one is great, and a new propellor 'cos the 2030 rotates in the opposite direction, you'll also need new inlet filter system, new flexible fuel pipes and new morse cables.

You'll probably save quite a lot choosing an engine wot goes round the same way as the 2003!! and even more if you can maintain the position of the coupler and avoid a new propshaft as well
