Post subject:  gtr 35 speed problem

I have a question about a GTR 35 on a 1752 alweld boat. I just got it repaired because the diodes went out in it so it runs great but i used to go alot faster over open water. I was fishing yesterday with three people in the boat and a full load of gear doing 26 mph across the shallow water but went i went deep i could not get above 18 mph. Does anyone know why it would not go faster than that over open water or is there a way to fix that. it used to do alot faster.

Is your hull in great condition on the bottom?

The throttle cable seems to be ok but how do i check that? My prop is a little chewed up from sand but it doesnt look that bad? with just me in the boat it will do near 30 mph. I guess the problem is in open water with a load it wont get up on plane.

What if i put some sort of cavitation plate on it would that do the trick?

I have the same problems and I am running a 1752 gt extreme and I had three people in the boat with a fishing load and it would only run 18mph. The motor would only turn around 3400 rpm's and usually it runs around 3800 rpm's.

Pull the throttle cable at the screw until you have a 1/8 of play at the handle while running
