A discussion for you dual sterdrive owners.
I am new to dual drives as well as Trim Tab controls.
Much simplier in my runabout with a single sterndrive, no tabs.
My manual states that a boat at cruising speed needs no trim. I do adjust them to counter balance weight loads. I leave them all the way down at idle speeds.
So my manual states that about a 5 degree up on the bow is ideal. No idea how you can judge this from the cockpit!
So this is what I do. Trim tabs full down, Outboard trims full down, WOT until on plane, then trim the Outboards up a little (about 1/4 up trim), adjust Trim tabs to make boat level.
I am sure this is a unique to every I/0 setup and am curious as to how the rest of you trim yours.
Thanks
