Motor Trim Pin position

[Wish-I-Were-Fishn]

I have a 50hp Yamaha 2 stroke with trim/tilt. It has a multi-position stop pin that restricts the down position of the motor. Where do I set this?

Do I put it in the lowest hole and adjust the trim each time, or do I find the best running position with the pin in and only use the trim/tilt to raise the motor while launching, but put the motor all the way down till it rests on the pin while running?

I would try it in the lowest hole first unless it feels like it is plowing while trying to get on plane.

Like Bruce said start at the bottom. Use that as a stop limit when you trim in. If you need to trim that far in to get on plane then there you have it. If your bow is plowing water then bring it up one position and try that. This trial/adjustment should be done with a normal boat load and weight distribution.
