That's an awsome set-up!!! I'm considering going from the Yam 250 2s to the Suzi 250 4s also. Did you have to change brackets to increase the flotation?? Are you running the alum. or glass bracket??

My attention to detail calculating the MPG isn't exactly 100% rounding up to the nearest hundredth (in case anyone checks my math skills 3.03, 3.11, 2.48, 2.22, 2.08). Anyhoo . . . I am amazed by the fuel burn numbers with this combo.

I'd be pretty dang pleased with those numbers Chuck.

I'm at 2.8mpg @ 4200 = 26mph right now.

I moved the motor's up 2 holes. It was 2.3mpg @ 4200 =25mph.

I'm moving them up to the bottom hole in the near future.
I believe I can go up on the pitch too. 18.5's now, going to 20's. I don't have the money for prop's right now.:(

This is the same bracket...it's fiberglass. If I remember right this motor weighs about 80 pounds more then my old Yamaha 250 2 stroke. I used to have a 15hp 4 stroke kicker mercury (125#s)plus the old Yamaha 250 on this bracket and together the weight was more then the 250 suzki.

3mpg is very impressive. I need to save my pennies and repower the old Mako.

What is almost unbelieveable is that strick's boat hits 6K easy and will bump the rev limiter with 3 200lb guys and a full tank. I'd be interested to see how his boat would do with a 21pitch.

Sound's like she has more room for tweaking. :)

I'm no tweaker ;) so I wont be changing anything for a while. I'm really happy with the way it performs. It get's up and goes. It seems every bit as fast or faster then my Yam 250 2 stroke was. Trim tabs are a must because the extra weight/speed that I now have will make the boat porpoise slightly. Easy to adjust by tabbing down slightly.

With the motor hitting the Rev limiter there is room for some more pitch to be added.

It may slow the boat out of the hole by 1 or 2 secound's, but so what.

It should increase the top end speed and lower the cruising RPM to get even better fuel millage.

Chuck - I'll keep my eyes peeled for a Rev4 19 or 21. You know you want to tweak that boat.
