I have been using my motor for a few years now was wondering what i could do if any thing to up grade it ?

On the enigine yes there are lots of things that can be done to it,head work,carb,exhaust,cam,pistons and connecting rods. You name it it can be done.

Look through the engine and mods section of the forum. ..

Its a 35 B&S - get a stage 1 done.

Same engine on all the surface drives on here....

Thanks will take a look into it!!

Darryl4444, is the 35 an LT? The bump-ups on shorties seem worth it, though my quick math came up with almost 1K$ for each 1 mph of gain...trouble is on the LT, that without gear reduction, more rpms reach a level of no gain because you can't spin a larger prop. A couple of guys here did the head work on smaller blocks (23 and 225) but the gains were minimal. I figure the posted mods would be sort of equivalent to advancing the stock throttle setting. I got about 3 mph faster with that but that's it. That was no cost and took only a couple of minutes. I'd be glad to hear anybody here who owns an LT and did motor mods and state what specific gains they made.

I don't remember exactly who maybe b coonass did it but he had a gd lt that was torqued up. I don't know what prop he ran on it but it was much faster than a regular lt. If that's what you are looking for.

Didn't his lt run right around 30?

Dang! Running 30 on an LT! Heaven and hell in the same ride- meaning hold on for dear life! GD rates the 35 HP LT with a 10x6 prop...a 10x9 on a 9HP with clutch; 10x4 on a 31 HP. After I tweaked the throttle on my 27 HP Kohler MB LT, I had to switch from the 9x7 it is rated for and came with, to a 9x6 to realize the gain. The fastest speed (22 mph by myself) was obtained on the 9x7 but I had to run it half out of the water like a surface drive! Fun but not practical or doable to turn! Now, has anyone run a 10x6 on a 25/27 HP LT?? I bet GD and all the other LT mfg.'s have experimented with all the sizes, but I still think there is room for improvement. I am hoping b coonass can chime in. Wonder what hull that was on?

Yeah, it was Brennon (b coonass). He had a 31 that was modded.
