Our Montauk with Suzuki DF70 turning a 16" prop on a set back bracket pulls and leans to the right when you get on a plane.

I think the reason it was going to the right side is because the last owner always used it with a heavy trolling motor on the left side of the bow, so I figured that the fin under the calvation plate needed to be moved back over.

Yesterday I went to move it, I was going to put the fin right in the middle and see what happend. The way the teeth in the fin go into the teeth in the motor it won't like you put it straght, is has be to the left side.

Why don't they make if so you can out the fin in the middle? Whats the best way to fighure out the best adustment?

If boat pulls to right, swing the trailing edge of the fin to the right and vica versa!

I guess the only way is to watertest it a few different ways.

I still don't understand why the fin can't be placed in the center.

I was told that it may have something to do with the prop, would moving up to a 17" prop help?

Move the trim tab as Clark instructed to take care of the pull to the right. Then, try moving people and gear around to get flattened out.

Before you go messing around with props, log a few hours on the water. You will find that engine trim makes a huge difference on steering torque and lean. As you trim up, the steering will neutralize. Experiment with the trim tab until the steering is neutral when the boat is trimmed up to where you like it.

I concur with Newt. I have noticed that trimming the motor can make a huge difference in the boat and the steering. My 75hp Mercury was pulling to the right to the point that it was un safe when I first bought the motor. I turned the trailing end of the trim tab slighty right and it helped.

I always seem to have to trim the motor slightly different in various conditions. Once you find that "Sweet Spot" try to remember where the motor is trimmed.

I just switched from an aluminum (12.75 x 21) to Rapture SS prop (13.25 x 19) and am happy with the results. I did have to change to a new trim tab as well and may need to do some adjusting again. The manual says to start with small adjustments first.

We'll have to just play with the trim and bring the socket set to move the fin around the next time we have it out.

I wish I could say it would be this weekend, but with me now working full time and my dad working more then normal it may be a while. We plan on taking the boat to Maine in a few weeks. Hopfully we'll get it out at least once in the harbor between now and then.

what are you smoking? (payback) obviously the previous owner reemed of the center guide that kept it in the middle. if you try to overcompensate by moving it side to side you are just putting more pressure on the motor, etc. do you have trim tabs? if not either try those(they wil definitly work, or get it repaired to place in the middle, thats where it belongs, under normal conditions.

I don't agree that the tab should be in the middle. If you run in chop most of the time, you will probably be trimmed in much tighter (to keep the bow down) than if you run on protected waters where you trim out for max speed/economy.

You could set the trim tab to provide neutral steering with the bow down, or you could set it to provide nuetral steering with the bow up. There is no right or wrong trim tab setting that will cover all conditions.

As the propellor spins it gets a better bite on the clean water under it than it does on the disturbed water between it and the cavitation plate or hull on an inboard. A single engine will always pull/walk that way. Ever try to back up a single inboard. (why do you think they make twins counter-rotating). On my 170 with 90 hp 4 stroke Merc I've got it set at two clicks to the right and It's totally neutral at about 20 knots. BTW since I got the 4 stroke I'm not smoking anymore.

Center guide----could you tell me what that is?
Do I have trim tabs?.... if you read my post you'll see that we are talking about a Montauk....... they put trim taps on montauks? Since when?
Don't pay any attention to holiberry , he clearley has no idea what he's talking about.

I know that it shouldn't be in the middle, I just figured that by putting it there we could get an idea of what side it pulls to and where it should be. We are going to play with it and make the adustments on the water. We haven't had the rig a second time to do it yet, we shall see on the next trip.

You will indeed have to experiment. I had the same issue and through trial and error found what seems to be the best position. I can tell you a little adjustment goes a long way, and the loading of the boat has significant impact on it as well.

Just mess around with it a bit, I think mine is one "click" over but all setups will be slightly different.

you know ryanwhaler, this site is for opinions not for immature remarks. opinions that are sincere are just that. don't turn this forum into a personal bashing, disrupting the integrity of this way too cool website. i will not respond again to your unusually immature remarks and keep it up. remember you might need a brother one day in the water and it can come back to haunt you...smooth sailing...........

I just got back from a nice night on the water, we took the sockets, to play with the setting of the fin and found the sweet spot.

A lot of it has to do with where the people in the boat are standing and how high,or low the motor is trimed.
