Just Fine,
I have the same exact hull and set up as you and am considering a re-power as well. I have heard that the Suzuki 175 4 strokes are a good way to go also. Since they're an inline 4 they are as light as the 200HP Yamaha 2 strokes, and what I have read, make plenty of power. What i haven't been able to ascertain is what kind of mileage people are seeing and at what cruise speed. Like you, I have long runs out to the ledge from North Florida and the average round trip for me is 200 miles. Increasing fuel economy could make for a big savings.
Grass Is Greener,
Could you share with us what MPG you are getting with the 175 E-Tec's and at what cruise speed please?
Thanks
