Princess 45 Fitted with TAMD71A engines

[PaulRainbow]

I'm going to look at a 1988 Princess 45 fitted with TAMD71A engines, anything out of the ordinary to look at with the boat or the engines in particular ?

What sort of fuel consumption would one expect ?

Hi
from memory I think you’ll see approx 18 ltr p/hour per engine at cruising speed ( not full speed) obviously less at slower speeds, will just depend on conditions and how much of a hurry you are in!

Surely it’s more like 100lph at 20 odd knots

Yes, sorry OP was thinking of completely different engine (brain fart) had a quick browse about and anything from 90-120 lph at 20-22 knots cruise.

I’d think of paramount importance, would be to make certain those engines are healthy. Check everything on and around them. A sea trial is essential too. Make sure the turbos are healthy. Make sure there is no sign of blue smoke once they are up to temps. Oil pressure strong and no sign of leaking injectors throwing diesel into the water at idle.
Check the reverse gear oil cooler’s pencil anode. That will give indication around her maintenance history and efforts previously. Wether it’s fresh or corroded entirely even.
The main reason I’ve suggested all of the above, is mainly because to replace these engines for anything equivalent these days…you’ll be out of pocket by at least 80k or more. Ask about everything and anything to do with the engines. Be lovely to see a meticulous service file and maintenance history.
My thoughts, should it help. Just from being around the tamd61 fairly similar engines, for a good while now.

Thanks for the replies so far.

Thanks for taking the time to respond. I'll certainly be checking all of those points. I'm reasonably familiar with some similar engines, i have a customer with a TAMD70, wasn't sure if they did anything odd with this engine, like fitting obsolete heat exchangers etc.

She is advertised as having a full service history and invoices for any work carried out, will have a close look at that.

Having bought a 435 with 71Bs some years ago, I'd recommend a full engineering survey.
