Hi everyone, I have a one of the original 1984 princess 45 flybridge yachts with its Volvo Penta TAMD70E engines from factory. We’ve overhauled them twice now and unfortunately I think they’re coming to the end so I’m putting some thought into a repower. I think it was relatively underpowered with its original 300hp each and I was thinking over moving up to the new D6 line of engines with the 380 or the 440. Or even possibly a pair of used engines in a similar HP range (I’d prefer nothing older than 10 years) to save some money. I would love to hear the opinions or suggestions from people who have more experience than me with these engines and repowering in general. A couple questions I’d also like to ask is with these new engines what is the possibility of the new Volvos fitting the same engine mount locations as the old ones to avoid having to redo them and do a lot of fiberglass work? And I’m assuming obviously I’d have to change the transmission as well but because of the power increase would I then have to change the propeller shafts? I’d like to think with s maximum increase of 140 Hp each engine the shafts should hold up fine but I don’t know enough to be sure.
