Re: KICKER QUESTION
I have a Merc 500 50 hp on a 20-inch transom, and I routinely use short shaft (15 inch) kickers ranging from 4 to 10 hp for trolling and as a backup. You'll go faster if you can get the cavitation plate down even with or just below the hull, but no worries if you can't. You just won't putt-putt-putt along as fast, that's all.
