That is not the case on my boat. The Imco neutral box figured in the degree of my transom on my application for some reason. I had a 71/2" prop shaft height stock, now with a 2" shorty and box I am at 51/4"...... The 25 your speaking of must be "Wilcard" and what a sweet 25 that is..... Wish I had Mercurys help on mine and someone that could really dial it in! Good luck with your testing and keep us in the loop on your results.....

SD, your boat runs real good based on what I saw at St. Clair. If it is staying together have fun with it. Laughing about all the speed lie comments. Ran with a friend this weekend, walked away from him easily. At the next stop, he says "how fast were you going?", I say almost 75GPS, thats all I got. He's like, mine runs 78-79 all the time, how are you passing me? I just smile lol. When it comes down to it as stated previously, when the water kicks up, they are all plenty fast. Thats were mine shines, 70 in 3-4's makes almost everyone else disappear.

Hahahaha, we always call a GPS the "Lie Dectector". The guys that run 70 and tell eveyone they run 80 hate it!

The ext box whacked 5+ mph off my top end and killed the boats ability to carry bow in rough water no matter what prop I used and shortie would let boat blow out around 95 mph, drop the bow and try to swap ends. I think that stuff might have helped mine when I only had 700-750 hp and was running in the high 70's/low 80's but I really feel as mine goes faster it rides higher and it reaches a point where moving drive up makes it lose all it's bite, 5 blade might help but with 1000 plus ft lbs of tq I have already seen how fast you can break billet shafts when I tried them, I have all the top end I can use so I quit trying to go even faster, Smitty

Heres is Quents beautiful 100+MPH 2750 Mid Cabin Open Bow.

I copied Quents paint style he on his 24 bowrider with a 710 in it.

1000HP Dustin whipple BBC on 93 octane.
950 on 91
SCX upper Sc lower.

I wish I had my hatch pad made like this with the cushion surrounding the vent as pad is much easier on the elbows.

I also like how Kevlar looks in the mold.

Thought it was worth throwing out there.
