Boat is pulling to the right like a motha????

[Gar-balls]

I bought a 19' Express (aluminum) bass boat about a month ago.  It has a 150 yamaha with a 4 blade prop. I dont know the pitch.  It pulls to the right; due to the tork of the prop. i guess.  i put a trim tab on the skeg.  this seemed to help some.  the pulling is the worse when im trimmed up and running high rpm's.  Any suggestions???  It does not have a no feed-back steering system. Do you think this will fix my problem?

Don't waste your money of NFB steering.

First quess is you are running your prop too deep.  If you have a water pressure guage you can try raising the motor 1/2" and make sure the water pressure does not drop below factory minumum.  Then start raising it 1/4" at a time.  Four blade props will rip your arms off if they are too deep.

Next would be bow lift, if your not getting enough bow lift.  If the bow is running too deep, from too much weight or not enough lift.  The wetter the hull runs, the more the steering torque.

Thanks, ill try to raise the jack plate.

You can adjust the trim tab on the lower unit. If its pulling to the right turn the trailing edge to the right. Its just a single bolt you can loosen and turn the tab.

Uh, Hale?  Wouldn't you want to turn the trailing edge of that tab to the left?  I would think that would put the force of the water on that side of the engine forcing the bow in the same direction?

Actually, the tap sticking down would adjust to the right as you are looking at it from the back of the motor.  He has already said he installed a skegg mounted torque tab, that will do a lot more than the tab on the back of the motor does.  If the motor is up where it needs to be, most of time the one on the back of the motor does very because it's hardley even in the water at WOT.  A lot of times you can take them off and they make no difference.  I did however make the assumption if he knew enough to install a skegg tab, he knew enough to have already adjusted the motor's trim tab.  May have been a bad assumption on my part though.

I have the motor's trim tab turnned all the way to the right.  It did not improve the pulling at all.  thats when i went to the skegg torque tab.  i think the trim tab is out da water when im running.

i do have a water guage.  so ill raise the motor and see what happens.  i hope to get to it this afternoon.

thanks
