[francophile51]

After the break, I am going to look at a1990 version of the Corvette 32.Will be very grateful If any owners on here can give an idea of any particular things to look out for,.
Similarly, as the engines are getting on in years, does anyone have a ballpark figure for the cost of a rebuild?

I have a TAMD41p, although in a different boat, and is a great engine. Mine has done 2000 hours. Mine is rated as 200hp and thought the 150hp was the MD41, without the turbo and charge cooler. Why do you think it needs a rebuild????

Well regarded version of this engine sans all the "designed to fail" sophistication of superchargers powered by glorified elastic bands and controlled by relays and the "Do not get Wet" electronics of later engines.
Volvo spares availability , both OM and aftermarket, that the owners of other makes of engines can only dream about.

Thanks for the replies.
The ad for the boat states TAMD 41 with 150 hp - as you say it looks like model or hp wrong.
It's indicated that the engines need some work. My rebuild question was anticipating a worst case scenario.
Good to hear that engines are well thought of and spares are readily available.
I have contacted the Corvette forum.

Many spares on ebay, one word of caution pre purchase, have a very good look indeed at things such as oil coolers/ heat exchangers and risers. Its usually the bolted on bits that cause problems , especially anything involving aluminum

At that age I’d be taking a close look at the fuel tanks and the decks.

The correct designation for the 150hp version was TMD 41. It was the TAMD 41 with the turbo charger but without the aftercooler (the T and A of TAMD. I think the MD stood for Marine Diesel).

+1.
Especially if they are mild steel, on most boats its an engine out job and probably a deal breaker .Several ££ thousands and weeks ashore.
Recently a 2003 Princess 41 had to have both tanks done.
Possible sheen of fuel in bilges and pervading diesel whiff could be clue.
It gets in everywhere including the upholstery over time and is very hard to disguise, needs sorting quickly.
Problems with rot on wooden decks. ?
My little book states

Corvette Marine Produced 30 between 1974 and 1977 before they went bankrupt.
In 1984 the moulds were purchased by Corvette Cruisers who built about 70 boats.
Most early boats had a pair of 106HP Volvos on outdrives or 105 HP Mercedes on "V" drives.
Top speed 18 knots
Later boats most commonly had a pair of 210 Cummins alleged to give 22 Knots.

Thank you all for your comments. Just received a belated post Xmas response from the broker. Teak decks need replacement. Both engines need attention - one with low/very low oil pressure. Several other less serious niggles but he passed over the question of tanks integrity. Pass.
