So I resently bought a 06 GTR 35 H.P. from a buddy of mine it has only 100 hrs. on it. Its on a 18 ft go devil boat it a center consol. Wondering what mods yall think would best suit the combo. He says its runs 22mph at WOT. Im waiting to get it from him to do a few test with the RPMs.

Get rid of that godevil boat and get a GatorTail boat and you will be much happier

With a motor that old make sure prop is up to par!! That could be one reason only seeing 22 out of it

Well the boat is kinda heavy it has a gun locker and to dry storage boxes and big front deck

Check prop 4 sure. 100 hours is plenty 4 a prop to b shot. Wut transom angle do GD boats have? Mite consider wedges 2 make the most out of your setup. Heads and exhaust will make the engine better. U can spend the extra on a carb later if u think u need that headache.

Check the flotation also could be water logged!!

what do yall mean by the flotation

What RPM should a factory 35 gtr run mine only gone up to 3100

4250 OUT of the water/ neutral rpms. In the water empty you should see 3800-3900 trimmed right.

3800-4k

Keep trimming up till u start loosing speed then trim down a lil and that'll be ur sweet spot. Also I run my motor just to where I can see the lower bushing just a lil out the water

What is your neutral RPMS. Hold the throttle Wide open. The motor will surge and bounce off the governor. Read the tach and report back. If its below 4250 turn the Governor screw until you get 4250 in neutral then go run the boat again. When you drive trim up tuntil you hear the "Prop whine" then back it off till it just goes away... Thats usually the sweet spot. What are your RPMS there?

This pic shows where the adjustment is for the governor. Thank Deadbird8 for the great illustration.

See the governor idle tab in the illustration take a pair of pliers and bend the arm in or out to get your idle back right!!

ok i will try

Let us know how that worked. The idles screw in the front is for minute adjustment, the tab controls most of it.. Heck my spring broke off the governed idle tab and it stays put about 1200 ish. I guess ill let it ride lol.

check if you can push the throttle slide back with your hand, if when you push it back and it stays at low idle where its supposed to be then soke it down with some sort af lubricant.

the throttle slide could be sticking with the extra tension on it.

So now im kinda thinking about doing a stage 1 by hoyt. I was wondering what does his stage 1 consist of and how much? i plan on calling gt and talking to him but wont have time till next week just tring to get and idea before i call him

Heads, Cam, and exhaust was the norm for his mods.
