Those "Tilton" racing style high performance starters have only the drive gear exposed,not sure how waterproof they are,but at least the "nose" isnt wide open like a stock GM starter--they might be worth the money,I've seen them for about 150 bucks--and they can be rotated to miss headers and other obstructions,not to mention more cranking power than stock. /forums/images/graemlins/crazy.gif
