RE: Got The Porpoise BLUES! PLZ Help
the porposing problem can be stopped by adding a elevater {small} to the outboard side of the
rudders with up angle of about 10 degees.
It worked for me as I can't use any thing in the water as I have lily pads in my lake.
changing engine angle and position didn't help.
The tabs also make it dig in on the turns keeping it from flipping.
