I have a zodiac cadet FR 285, Mercury 6hp four stroke.
It will just plane, one up, after carefully checking tube pressures and experimenting with engine trim.
With heavier loads it reaches the point where the bow rises and it feels as if it is "trying" to plane but doesn't quite make it.
I appreciate planing is a tall order with 6hp, but I'm considering a couple of solutions.
Firstly, would a set of Zodiac Nautic - Accessories - Black flap kit (trim tabs)
Secondly, would changing the standard 8 inch pitch prop for a 7 inch give the necessary extra thrust to get on the plane?
Any other suggestions, apart from the obvious bigger engine? (Zodiac recommend 3-6 HP, maximum 8 HP)
