I have a Marinette (for sale right now), and I have been using Trilux-33. Seems to be the best for aluminum boats. It took a gallon for each coat on that boat (32-ft). Recommend at least 2-3 for any boat.

HOWEVER.... If you take it down to bare aluminum with a good media blast, etch and prime it properly, then put on a barrier coating (IP-2000 is perfect) then you can put whatever paint on there you wish. The key is absolute isolation from the aluminum hull. A good quality barrier coat does just that. It is expensive the first time (and only time), and should last the life of the boat after that. This is providing you have everything that should be isolated (shafts, rudders, etc) from hull as they should be.
