I got my new rig abt a month ago and I haven't got very good speeds out of it. I'm running a 1846 gtb with a stock 35 gtr the best speed I've got has been 27 that's me (250) 1 battery life jackets and ice chest I thought it was just because of my weight but my buddy (rocket man) drove it by his self and the same he only weighs proble 140. Any help will be appreciated.

Sounds about normal. Deep water conditions? Shallow water conditions?

What hole is the motor on? I run mine on the middle hole trimmed all the way up....when I run top hole, I loose 3-4 mph......

sent by carrier pigeon...don't shoot it!!!!

On my top hole i gain about 3 mph!

Why do you people think you can get these high speeds from an engine that actually only has about 31.5 HP on a big ass boat.

I think the sales guys at PD, GT , MB Etc blow alot of smoke up everyones ass.

These things were not made for speed. They were made to get us to the pond or stand.

I think its alot more along the lines of people online blowing smoke up peoples asses. They go out and ride and hit a shallow area, their gps reads 30 mph for a minute, and so now they have a 30mph boat.

I would expect 27-28 to be a good average speed in deep water for that boat. My 36 PD before mods, on two 1848 hulls with 3/16th bottom, ran 27-28 consistantly in deep water.

Your speeds sound about right. Wait 20-30 hours and have a valve job done, and you will probably pick up a little extra speed.

I'm running in the middle hole I would be fine w these speed but I have read other Lol w the same combo as myn Getin 29 bumping 30 all day long never heard of 1846 w a stock motor running 27 solo and light and yes its deep and shallow water conditions even w another person it runs at 27and that's just kinda bumping 27 26 steady

What rpm's you running

At abt 3900 is when its getin 27 if I trim it up any more it goes back to 26 around 4100

It's prolly just leaky valves.

thats what i was thinking ^^^ you sould be up to 4000-4100 running trimmed out wot....

See that's what I was thinking to but I can trim it up some more and it will get up to like 4350 it shouldn't be Getin up that high should it

watch that gps and find out where the sweet spot is.... modded motors turn above 4350 so there is no danger there, but find that sweet spot.

The sweet spot on myn is around 3850 I get 27 but if I trim up anymore then that it starts blow in out kinda and I go back down to 26 mph

Set your out of water rpm's at 4350.

Yea I think it has something to do with it not having enoughf throttle at my sweet spot

Do like DDM said, but 28 is about what I run in mine on avg. This is the 3rd motor on this hull & that's been the avg solo speed for every one.

Yea I'm gonna try that camo thanks everybody for the help

Alot also depends on where you have tour weight. Moving a 5 gallon spare gas can or ice cheat forward or back can increase 1 mph some time. Centered weight can help also. When I has my rig set us as tiller some one said that moving left or right can increase / decrease speed. I didn't believe him until I tried it. Its a fact Jack. I like most have spent a small fortune trying to get a few MPH more. The HP to cost ratio on these motors are stupid. Do I regret it hell no cause I like the extra power.

I guess what I am saying is there are so many variables that can increase / decrease you speed its crazy.

I have the same boat 1846 gtb with 35gtr and I have never got over 27 and I have increased my out of water rpms. I never get over 3950 ish unless my props wore down. Its could be the valves right?

Is 2mph really making you lose sleep? lol

Zibilich Naw its not making me lose sleep but I but I just played a lot of money for my rig I wonta make sure everything right on it and what everybody saying is I should be running faster... I have my tank up front w 6 gallons of petro in it and a ice chest w nuttin in it unless my wife's w me she's a drunk Lol jk

Orange foot...where are you located?

^^

Haha!

I live in Winnfield la

How do I set my rpms

There's a Phillips head screw inside a spring on the throttle linkage bracket between the exhaust & engine. Standing on the starboard side of the motor, looking towards it, you'll be facing the screw head. Tighten=higher rpm, loosen=lower rpm. You won't be able to get over 4300 because of the coils, but try to turn it up to 4250-4300 at WOT in neutral.

Thanks that's what I thought just wonted to make sure

My 1846 runs 28.5 with 2 ppl
