Here's another newbie question. <br /><br />I've got a 48SPL with a manual tilt/trim and I don't know a thing about the manual trim. I've been using the boat with the motor locked all the way down, assuming the trim is fixed. Is this true? Should I be doing something different? If so, is there a post I can read on how and when I should adjust using a manual trim?<br /><br />As always, your help is appreciated.
