I'm not sure. The digital gauge isn't working. I just know that when I adjusted for more throttle throw, the engine didn't rev any higher than the setting that it was at previously. I have a new digital tach that I have to install before the next time I take it out. What should be the WOT RPM? I thought I read 5500-6000.

With the correct prop and set-up I expect that you should be able to get closer to 30mph with that combo.

I think you're in the ballpark. You might get a little more by playing with props, but I wouldn't expect more than a couple MPH. That deep V hull is heavy and drafts quite a bit of water, it isn't made for speed.

Motor is four stroke. Forgot to put that.

I was basing my estimate of 30mph on the fact that I have a Starcraft 160 Patriot (12 degree deep V) that does 24mph (gps) with a 25hp 4s merc. While his side console will make his boat slightly heavier, my "V" is probably even deeper.

I tried to see if I could see the throttle body butterfly at WOT, but it seems to be buried and a pain to get to. I have the tachometer hooked up now so hopefully I can get a WOT reading to see if it's in the 5500 to 6000 range.

Hope to take the boat out tomorrow.
