trim tab on lower unit

[rbigg]

'77 Johnson 115hp. <br /><br />How do I set the trim tab vane on the lower unit? <br />It's easy to physically loosen, set, and tighten. However, what I'm asking is where to set it, how to know if it's the right setting, etc. I seem to remember it's some kind of trial and error thing, but I don't know what to look for. Please give me a quick crash course in the care and feeding of that thingee.

rbigg,<br /><br />You're right. It is trial and error. Set it, first, dead even with the skeg on the lower unit.<br /><br />If your boat develops a pull, then set the trailing edge of the trim tab in the direction of the pull.
