 18x54 GTB with 35GTR
well yesterrday i was able to pick up my boat from gator tail. I put it in the water about an hour later and i love it. It is the extreme hull and handles very well. It has hoyt's stage 1 (cam, heads, exhaust). When i took it out it was me (240lbs) and a buddy (150lbs) 9 gallons of gas trolling motor with battery ice chest with budlight and the normal boating stuff. I was only running 26 bumping 27 @4150rpm, same stuff in the boat and just me 28 bumping 29at the same rpm. i think i should be getting a little more out of it I have seen the same size boat on here with stock motor on here running the same speed. thanks in advanced.

 Re: 18x54 GTB with 35GTR
I have done that already the best speed I get is @ 4150rpm. The prefilter is gone also, and it also backfires when revving down. Is that normal?

 Re: 18x54 GTB with 35GTR
What octane fuel are you running? Also you have to think about how much boat sits in the water. I have a 17x54 gtb and can bump 30 by myself(when I can keep the bow from bouncing). My buddy had a 18x48 build by Uncle-J with a 7.5 ft rake, he doesn't have much sitting in the water once he gets on plane. He has less drag and weight than what I have and stays infront and gets on plane quicker(maybe 20 yards in front).

 Re: 18x54 GTB with 35GTR
I run 93 and it's gets on plane very quick and has loads of power down low. Would a carb help me with top end? It's it worth the money?

 Re: 18x54 GTB with 35GTR
It's only had about 5 hours on it when I got the speeds, will it get better after it breaks in? Should I just call Hoyt and tell him what's going on and go from there?
