I've been around boats for a while. Not all my life but a while. recently I picked up a 07 2110 w/tunnel nauticstar bay boat. The boat is outfitted with a 200hp optimax, 17p rev 4 prop and 6" jackplate. All batteries(4 of them) are in the center console. The boat is also outfitted with trim tabs. I have noticed that while on plane and attempting to untuck the motor to the point the steering feels slightly free I can not get there as the boat will begin porposing long before that feeling occurs. To get the steering feeling free I have to put in 1/4-1/2 trim tabs. Obviously that's not the best way to run. Anything short of that has me using two hands to steer. Especially in the opposite direction of torque.
Also I have notice that while on plane the boat will list to the left. I generally have to put in 1-2 clicks more trimtab on that side to counteract the force.
Lastly if I'm just slowly cruising along and I put in all of the trim tabs the boat will try to turn rapidly. I've only done it once on accident and another time to verify. Nothin at high speed but enough to maintain plane.
My questions are this.
1. Shouldn't I be able to trim out my motor to have relatively loose steering feeling or is it all dependent on the boat?
2. would the prop be causing the listing? Also is the rev4 more a bow lifting prop?
3. Any ideas why the trim tab actuation would cause a pull to the left? Is it that the tabs are pushing the hull out of the water so much that the torque of the motor then takes over?
I'm kind of at a loss
