I have a 74 23 Tsunami powered by a 260 hp 350 Mercruiser with an Alpha drive.Wide open throttle I get about 35-36 MPH on the gps.I cruise at about 25 at 3400 rpm.Now if I can just get my tach to perform properly.
I'm not all that happy with the top speed,but oh well,in every other aspect it performs flawlessly.
I spent countless hours searching for the right prop.and ended up with a 15x17 Mirage plus stainless prop.This has been a good performer for me.There is no lag at all to get on plane,and it does well across all ranges.
If money was no object when I powered it,I would have gone with the 383 stroker and a Bravo Three drive.I think the Sceptres/Tsunamis need much more power in the I/O configurations than 260hp.
Lew,& Floorboy,- Volvo has some 350 5.7's that are pretty sweet in 300 & 320 hp models available with carburetors or fuel injection.Pretty nice if you don't mind spending 10-12 grand.
