Re: repower
Blackfin,
Prior to buying my 2003 SeaCraft Master Angler I looked at two identical SC20s, one with the Yamaha 150 HPDI and the other was the 4 stroke. It is a little known fact that the two 25 inch shaft engines weigh exactly the same. The big difference is that the 4 stroke is actually a smaller 4 cylinder engine and the 2 stroke is a six cylinder. The six which is what I actually picked for my boat. The HPDI makes more low end torque. I was told by the Yamaha Dealers locally that the 4 Stroke was actually designed to be used as a twin in applications such as the Pathfinder 23 Offshore. They seemed hesitant to use it as a single.
