Changing a volvo penta md32 to what?

[john-m]

Think I had enough of my old md32 on shaft drive and want to change it.
I want to change it for similar horse power but have no clue what to look for. Has anyone changed one out for something else.
My boat is a fjord 27. Also needs to be realistic price

Thanks john

you need to be precise about what you dont like about the set up.
if it runs, may be better to change the boat ?

Engine is still running but wouldn’t be able to sell it the way it is. Also if I go and buy a new boat the engine in that is likely to be 30/40 years old.

What speed does it run at I suspect that as it’s still running it’s under 3000 rpm in which case from memory it’s about 75 hp (small horses though)

Maybe have a word with Lancing Marine

 

[john-m]

I’ve never really been over 2500rpm as it smokes and starts to get hot over that. It’s meant to be about 100hp

What's a sensible price?
An MD32 was something like 105hp, I think.

I though you only had a 4 pot for some reason John, Lukes fjord was a lot of fun with a tamd41 in but not cheap to buy.
Am I right in thinking md32 has aluminium head? Always a weak point once overheated.

 

[john-m]

£2500-3000 maybe a bit more.

The last 41 I sold made 4 k and would replace your engine quite easily , to be fair if you don’t need the power there are other alternatives that are smaller and lighter .

 

[scottie]

Which gearbox do you have? There is some worth in the old unit I would think!
The 32 was good when revs are kept down but the alloy head caused no end of trouble if not torqued down on a regular basis it was way ahead of the alternatives at the time! But I doubt it ever produced 100 hp at shaft output.
Now the Kad32 (no communality except the paint) would be a nice replacement

Like an AD31, for instance.

It will be getting on now and if you want to keep the boat it might be a short term solution

Depending on what alterations you would have to make it could work out
Again what gearboxes are you talking ?

 

[john-m]

My engine has a Borg warner on it.

 

[scottie]

I think that it might match up with a 30 and is a better option than most
