I´ve been offered a 30 year-old, 37-foot wooden motor cruiser equipped with a pair of VOLVO TMD 70 AB diesel engines (rated at 230 HP/2500 rpm).
The hull is in good condition and the boat went into storage 10 years ago, at which time the stbd engine was given a major overhaul.
The vendor fired both engines last week and it seems that the port engine is in need of a major overhaul (lots of blue smoke, even after it warmed up). This boat is presently not seaworthy so it will not be possible to load-test the engines.
The price in Brasil for the requiste VOLVO parts - liners, pistons, rings, bearings, gaskets etc, - is astronomical (some 8000 US). Incidentally, VOLVO parts dealers in the US, did not response at all to a request for quotation.
Would it be wiser to scrap these engines due to their vintage and install a pair of Mercedes Benz OM 447 LA´s instead ? The latter would entail an extra 400 kg of gross weight, but effortlessly make 330 HP each while just ticking over at 2100 rpm.
Can somebody help, especially the Scandinavian wooden boat forumites ?
Thanks
