Engine height?

[Baxter0808]

So im new to this boat, Grandsport, and just redid it. Got a 12" setback, 260 on 15 mid, sportmaster. What height should I start at? I want some decent holeshot and handling while I learn the boats, high speeds will come later.

I’m running 1/4” below the pad with the lip. That’s where it was set when I got it and I haven’t fooled with moving it since I’ve seen that called the sweet spot a few times. Feels stable and forgiving at all speeds to me and this is my first Allison so it’s all I know for them. It’s a GrandSport with a 20” 200 ProMax and a sporty.

Any reccomendations with no lip. cmon guys help me out. only got 80.3mph on the first test run haha I know there is way more there.

without lip right now on a xb im at 1 3/8 above ive heard some even run as high as 1 3/4

I run about 1/2"-3/4" above the pad with the factory lip. You will have to run at least that height without the lip. I run Lightning ET props (28 & 30).

I need to get my hands on a Lightening ET for sure.
Thanks guys!!! be back out this weekend with a new engine height and hopefully a different prop

Dont over prop it. That setup will run 100 with a 26 inch prop and even with the pad and low 90's even with a 24" Trophy. Remember that engine needs to rev 7.5K to get in the meat of its power
