AT Trim Tab versus Boat Movement
#23
I did that after you showed me that little trick and it caused my oil temp to climb on the low side.

I like your train of thought, makes sense. It will be on the fine tuning list for sure.

Good thread! Being a new to boating I`ve been trying to figure out all the relationships between trim, tabs, etc.
Since day one the boat leans to the left so I have to have the left side set to about 4. the other side I keep at 0
This keeps the boat level but with lake Michigan chop anything over 40mph it keeps flying out of the water. using the trim to lower the bow kills speed and I`m sure eats more gas. Trimming up makes it even worse
This weekend I tried lowering both the tabs and that seemed to lower the bow for a smoother ride but not kill speed as much.. then using the trim didn`t seem to make too much difference..
Damn I got a lot to learn..

you can get in BIG trouble having one down significantly and none on the other side.
I was always taught to have them both in the water ..then add more of one or the other.
if say "3" is level with bottom of boat(assuming "0' is all the way up) then have both at "3" then drop high side to "4" and low side more(deeper)
