Re: Bottom paint & outdrive paint
The outdrive requires special antifouling paint for aluminum. Tri-lux is a good one, however it requires special primer. I have not had much luck with the spary cans of outdrive antifouling paint. If I were you I would make sure the outdrive is well painted (several coats of paint over a good aluminum primer) and then brush on two coats of Tri-Lux or other ablative antifouling paint for aluminum.
