I hate saying this to you Dave, but good luck, I have the enlarged tab on Phoenix Rising and it is adjusted all the way left and I still have torque steer with both stainless steel props I have used. I am starting to think that power steering is going to be the only fix possible. Or just dealing with it.

I am going to give it a try. I have the no feed back Teleflex steering, and have no steering wheel pull to right or left, but want to take some strain off the steering system. Possible answer is a tab on the skeg.

With my old steering set up, I could feel the prop/motor/boat going through the different stages of torque steer as speed's increased ...
Now it feels the same from 5 mph up to 50 mph ...
At 30 to 40 mph I can take my hand off steering wheel and boat will track straight for quite a distance before wind and waves start to take it off course.
I'm just looking to fine tune steering to take as much strain off motor/steering system as possible ...

At 50 + mph is my trim tab even in the water ?

That is why I am going with the extra long, extra deep fin.

I had alot of water drain from the drain plug after the 80 mile Mississippi run, which I attributed to a 25 year old drain plug with hardened rubber and the ribs worn down. I tilt my boat with the trailer wheel fully extended on a step stool for two to three days to make sure all the water gets drained. Went to Hannay's and bought a new drain plug today. They would not take the old one in trade. Talked to Joe and Don at Hannay's. While waiting for Joe, I got trapped in the Red Dragon Restaurant buffet for lunch.

Also went to White Bear Boat Works for a little touch up on the gelcoat from Mike.   

Now off to the car mechanic.

These days off are hard.

I wouldn't worry about a little water after a hard day on the river like we had.
You are going to get a little water from spray comming in between the hull joint under the rub rail.
I bet if you just let it sit at the dock it would be dry inside.

Don't forget you had your 2 sons in the boat and additional gas cans in the rear. All it takes are a few splashes into the splashwell and further.

Drain plugs are cheap. I keep at least one extra on board.

Believe you are right Ross. After solo runs on White Bear Lake, there is no or very little water. With all the weight in back with the fuel and one son, the Rake prop labored to get on plane. I have heard that before with the Raker prop - not very good hole shot. I really do not care, as I go for top speed. Greggs Laser II seems good for getting up on plane. It is a good skiing prop, able to pull skiers out of the water fast. Laser II was my ski prop with the V-153.

Put boat in water and checked drain plug ... could see a small amount of water seeping in with in a few min.
The 4200 I used was starting to get rubbery, maybe starting to set up ...
This time only about a cup ... Tipped hull up all the way when I got home ...

River was crazy rough today, only got 53.8 mph.

Put trim tab in center ... got torque steer at high speed ... maybe just boat being pushed by prop ?
Put it to the right and it worked good ...
I had it to the left last time out.

Thanks Rich !

Gregg, could you take a picture of the trim tab position on the Mariner?

It's on the first "notch" to the right.
Was WAY to rough today for any top speed runs ...

Thanks for the picture Gregg. Because your motor is raised higher than mine, you may not have as much steering torque. I am having the big OMC trim tab cut down at work next week. Your top MPH numbers and mine are just about the same. Interesting.

Well Dave looks like you are going to raise your motor or buy a bigger one.

You can't let Gregg keep up to you, Can you?

If you lift it Dave ...Check for splash well drainage first !
Your guys a work could make you some 1/4 spacer plates.
It made a HUGE change in speed and handling on my CV.
Cheapest 2 mph gain you can make !

Guess I am changing my thinking about a raised motor. Just want to make sure that the motor gets an adequate supply of water under all conditions and that the transom holes for the bolts are water tight. Also I need some feedback on how high to safely raise the motor in terms of calvitation plate above the bottom of the hull. Now plate even with the hull bottom. Raising one hole would put it at 3/4 inch above and rasing two holes would put it at 1 1/2 inches.

May put off this project until next spring.

Also thinking about buying a 23" SRX OMC prop.

I enjoy finding ways to make the boat faster by the selection of prop, moving fuel weight from the bow tank to tanks on the back seat, raising the motor, not to be faster than anyone else, but just to bring out the best in the boat and motor.

YEP ... Would be a good idea to get a water PSI gauge ...

Gregg, what is the distance from your cavitation plate to the bottom of the hull? Another trick is to plug the top or top two water intake holes, and/or ream the bottom ones larger.

A water pressure gauge would be great. I could remove the existing trim tilt angle gauge, which I never use (the rearview mirror or the sound of the motor is better), and install a matching water pressure gauge.

I purchased a new 23" SRX prop, probably more effectively utilized on a raised motor than my current motor height. The purchase did not meet with too much resistance from Joy since I sold a 2-blade bronze prop two days ago and have two props for sale.

I still get good water pressure at and above 50 mph.
I removed my trim angle gauge and put the PSI gauge in ...
