    Marine application in an I/O I would not run over 9 to 1 with iron heads or 10 to 1 with Aluminum. You just never know when your going to run out of gas and the only thing available is 87 or 89.

    Bowl blend and some match porting to a good highrise dual plane should get you another 30 too 40HP.
