Hard pull to the right @ WOT

[inthedirtagain]

On our maiden voyage under my stellar captain skills, I noticed that at WOT there was an incredible pull to the right. So much so, that if I let go of the wheel, we'd be thrown overboard and be dog-paddling back to the dock. The dude I just got the boat from had installed new steering cables last week. Both pulleys seem to be under nearly equal amounts of tension when sitting on the trailer, or just floating still in the water. Am I experiencing torque-steer and this is considered fairly normal? I've never experienced this with other O/Bs on a deep-V or tri-hull. Your thoughts?

I would check the trim tab which is located right under the cavation plate. It is more than likely not adjusted correctly.

This is the original 1966 Evinrude 100-s, and I don't see a trim tab under the cav plate. What is there is the water intake, and it looks like this:

On the very bottom, there is a little tab that looks like it is some type of support or brace to protect from rocks. It looks like it is dished in the direction of the hard pull. It looks like this:

I took it back out on the lake today after changing the position of the trim. I immediately noticed that the pull was gone and was able to run WOT without my hand on the wheel (scared the crap outta me to do it!). So really don't know what to say.

Pics aren't working. Too bad, I really wanted to see what would cause that serious of a pull. Cool that you got it taken care of though.
