How fast are you going Wesley, it may help these guys that know if these changes are going to get you where you want be?

Not fast enough. Trey you and Lonnie might be able to run me down.

You said you have a 74 or 76" bottom correct? In an 18' boat? I'm willing to be the narrow bottom combined with an 18' hull with that heavy motor is causing it to sit in the water pretty far, alot deeper than most would which is making it just plow water. Your boat is not displacing as much water as an 84" or 86" bottom is causing issues would be a good guess but could be the other stuff too

 

[wesleystokes1]

Idk. I'm sure its not the motor. The boat will run dry all day and night.

 

[clark3]

I think the boat is just sittin deeper in the water causing less drag take a pic of it siting in the water next time.

Top pics. Idk how them bottom ones got there. I did it on my phone.

pitch it to 4800 rpm and tell us what you think. My boat is a dog at 5000 or 5200 but wakes up at 4800. I have tried with with different props at various rpms and pitch. 4800

 

[mike]

Adjust the pitch.........a little adjustment can make big changes!!!

 

[clark3]

By the pics looks right. I'd say pitch a few more degrees till when youve got the pedal all the way down it won't turn over 4800 like they said

 

[GarGuys]

I think Clark is right. the torque peak is lower o adding pitch might help. Now that said, i think you will get your cruising rpm down some but not you top end. I think you have a big ding in the hull right about the fuel tank. have you looked under it?

 

[wesleystokes1]

no dents new boat

 

[silversurfer]

Who hull design do you have? Most time those super wide don't have the top end as a R blade or whisper tip.

no dents new boat

I know Im probably wrong since its a new boat but take a look at it sitting on the trailer and see if there is an area mid ship back that sits up off the trailer.

Im also wondering, I got a 16x8 with a 350 thats got alum heads,roller rockers,650 edel carb. I got it pitched so at wot it runs 4300-4400 rpm and im getting 38-40 mph out of it and I tend to get stuckish with 3 people and in like 6 inches of water. Should I also pitch it to run 4800?

prop is a 78 inch water walker 2 blade with a 2:1 ratio

 

[joe]

I turn mine 5400 and get 51 out of it. Still runs dry very good. I have a 78" 3 blade stump puller and 2-1 ratio

With that prop/red combo you may move it up a little bit not too much. We just did a 16x8 with that same prop/reduction and set it at 4800 and it would run dry with 3 guys same motor too. It also depends on hat rpm that motor is maxing out it's HP

 

[zeak]

Taylor I told you awhile back to pitch that so the motor runs towards 5 on that smallblock, i doubt your getting hardly any horse on that motor at that low of rpm.

 

[clark3]

Yeah then Small blocks need to turn some rpms to make the power. This motor was built for an airboat and was maxing out the hp at a little lower rpm

 

[Taylor Farrar]

Well thank ya fellers, Ill pitch it at 4800-5k

 

[TeamTailandScale]

I've seen Wesley's boat on plane, and it appears it is plowing, nose low, and kicks out water at the back of the deck. His motor is mounted considerably higher in the front than ours, and I believe it is pushing the nose of the boat down. I've suggested he lower the front, or raise the rear of the motor, which should raise the nose of the boat.
