Been boating for 20+ years, all inboards prior to the new boat. Still trying to get the hang of these twin 150 Yamaha outboards on the 24 sea sport. Curious how you guys work trim on the motor and trim tabs. Out of the hole I have trim tabs bow down, and engines trimmed down. Once on step I bring the engines up, until I see a jump in the RPM's. Advice from my buddy that has experience with outboards. My question is, at what point do you use the trim tabs to raise/lower the bow vs. engines. Or do you?
From 4k to 5k rpm I see about the same 2mpg efficiency. After 5k MPG drops considerably. at 4k I'm doing 30mph at around 15gph, at 5k I'm doing 40mph with 20gph.
