Re-Powering my 20 footer MA

[GradySailfish]

I have a 78 20 MA and she's powered by a 150 ETEC. I top out at a little over 40 MPH, but I need to tweak my prop. Currently I'm turning a 14 x 19 3 blade stainless wheel. I think I'm going to try some props suggested by Bushwacker.

Speaking of Bushwacker, he has a 20 Seafari with 150 ETEC and hung on a bracket. He ghets top ends in the middle to upper 40's. I hope he chimes in here.

As for overall performance of the engine, I'll just say right out that its outstanding. I only have half of one season on the engine, but I'm impressed so far. Fuel efficiency, holeshot, etc are all excellent. You don't need 200 HP for that boat, honestly if the 130 ETEC was around when I was putting new power on I would have gone with the 130.

I normally cruise at 3300, which yeilds a speed of about 22 knots and fuel milage of about 4 Nautical (or 5 statute) miles per gallon.

If you have any questions please feel free to PM me.
