Engine replacement?

[rich201283]

I have just pulled the engine out of my UFO 34 and the engine seems in a poor condision. The price to rebuild it is going to be quite exspensive, Can anyone recommend another engine that i could replace it with without spending thousands?

Agree totally with Sailorman, but there is now a smaller lighter 25hp Beta-might be worth a look!

Given the approaching winter, how about re-building yourself as a winter project? If you have a garage to do it in, and are prepared to take it slowly bit by bit, it isnt such a daunting exercise as you might think. And it certainly would be cheaper than any new engine.

Bear in mind that any new engine invariably requires some new installation compnents maybe even a new exhaust system. So the cost of the motor is only a part of the total.

Oh dear ... here's the Bank Managers friend coming down the road !!

You don't say what engine is the old one .... Why would I say that ? .................

Changing engine may mean far more than just an angine and few bits. It could mean and probably will as you say engine is real old .. a) new shaft, b) new coupling, c) possibly change prop, d) reposition / rebed mounts and bearers ......

I know - I did it and work / parts can easily add up to substantial outlay on top of just the engine.

So careful thought ... have a chat with local engine supplier to try and find an engine that is as close to original in form, rotation of prop, etc. to cut down extras needed. IMHO.

or

as another has said ... why not take time over winter to strip and work on old engine yourself ?

My Perkins 4-107 looks a real dog .. but mechanic who's just worked on mine reckons it's a good engine and should last another 40 yrs !!

Overhauling your old engine will be by far cheaper (unless serious problems with gearbox etc) and quicker. A new engine will need a lot of new things and a lot of time to get it right.

You try and rebuild a Volvo MD6A and see the cost of the bits, gets close to a new engine!!!

Volvo maybe ... but where does he say he has a MD6A ? If he's got a Perkins - then even an old London Taxi can provide bits !! /forums/images/graemlins/wink.gif /forums/images/graemlins/wink.gif /forums/images/graemlins/wink.gif

I'm not sure that the other respondents have really answered your question. I would suggest that you have four options - in order of cost..........
1) Rebuild your existing engine
2) Find a refurbished version of your existing engine
3) Find an alternative refurbished engine that will fit
4) Get a new engine

I costed a new engine for my 33 foot Westerly and was looking at £6K. You could spend £1K on a rebuild and, provided it lasted 3 seasons, you would be better off.

The engine is a volvo md2b 2 cylider engine

Pistons £260 each
To resleve the block £200
Bottom end gasket set £160
And the rest,lol

Thinking of looking for a 4 cylinder engine.

I have seen a nanni engine with a prima gearbox, Does anyone know how good the nannis are?

Be wary when considering a replacement 'cos there's all sorts of hidden extras.

My new engine was 50% of the final bill by the time we had a new prop, new propshaft, new mounts, new strainer system, new cables, new tubing, new stern tube, new deep sea seal etc. etc.

But it included an new gearbox, a new wiring loom and control panel with a rev counter and hours run meter.

My old engine rebuild was initially costed at £100 less than the new engine and I would still have had to spend an additional £1500 on parts that we noticed when we started stripping it down plus an additional £800 on the stern tube which had almost failed.

Reckon a new engine is much the best course of action and it pollutes less.
