Tiller Torque Issues

[fishrhunt]

I'm having issues with tiller torque that I can't resolve. I purchased a used 1775 Lund ProV tiller boat with a 75 hp Yamaha Pro on it. The motor runs good but insists on pulling the tiller handle away from me even when trimmed out. I've adjusted the trim tab several times but it is still troublesome especially with a crosswind on the port side.

I'm running a 13 1/4" x 17" aluminum prop and the motor is hung in the second hole from the top in a 4 hole row. I also seem to be experiencing what I consider to be more than normal cavitation when triming or cornering.

Should I lower the motor, change props, or ???? Suggestions appreciated.

Odds are the motor was set up right.First question how far are you triming the motor up? Until you find the sweet spot just trim the motor up slowly.The cavitation problem sounds like you have the motor trimed up to much. Next time you go out make sure the motor is in the down position and when you get on plane just slowly start trimming motor up and you will feel it when you hit that sweet spot. Also when you are battling the wind tighten down on the dampner A little bit and that should help with the toruqe. I run A 75hp merc. tiller and it took me A couple times out to figure out the trim. good luck

I had a similar problem with my ranger 18ft tiller with a 90hp suzuki motor. I have a stainless prop that bites really hard and it was almost unsafe to run in a heavy crosswind, because I needed both hands to steer. I had a local dealer install a titan tiller steering system on my boat. Basically it totally eliminated all torque, and I can drive my boat in a straight line without any hands at all! The downside is you won't buy another tiller without it, and it ran me over $1500 installed.

I had a Titan, and now have full hydraulic tiller steering.

I would say get the titan for sure; you will never have to worry about it.

I wish I could get the titan steer assist installed on my motor but they don't make them for mercury because they sold the patent to merc and now they can't make any steering systems for mercurys

A four blade prop should help both issues, but may not fix them per se.
