hello everyone. i baught my first pontoon last summer, a 2011 benny 20 sli. it has a 50 hp evinrude with power trim.
since this is my first pontoon i have a question for the trim setting. last summer i took a portable GPS unit out with me one weekend to see what speed vs. throttle position vs. trim setting seemed to work the best for me. i found that around 3/4 throttle i was going around 17-18 mph. adjusting the trim did not seem to make much of a difference in speed or the sound of the motor (more or less of a load on the motor). now if i opened it up completley to full throttle it could reach 19 mph. im not really concerned with speed, thats why i sold my ski boat in favor of a pontoon. my SLI does not have lifting strakes. so this is where im seeking some advice/guidance. where should the trim be set at? is it as critical on a pontoon as a ski boat? i have read the correct setting is wherever the motor sits at a 90 degree angle to the water (straight up and down)when the boat is running. the only thing i did have happen a couple of times was cavitation of the prop, obviously from having the trim set too high. so any insight would really help.
thank you in advance.
