using OMC trim

Question
I got my first boat - used 1984 Ebbtide 156ss with a Evinrude 90hp outboard.  How do I use the trim properly?  I am a new boater.

Hi Jeff...Thank you for selecting the undersigned to reply to your question.

It's all a matter of personal judgement via trial & error. The main thing you want to accomplish is getting the boat properly planed out smoothly, and not porpoising or plowing or riding bow high. It's all dependant upon load distribution of people, gear, equipment, fuel, etc. So, just keeping experimenting as you begin to approach 1/2 throttle and forward to full throttle. Play with the button. See which way the bow goes, up or down, and how smooth the ride is. It takes practice but, understand it also depends on the surface of the water and whether it is calm, choppy or wavy.

Safe Boating
