it all depends on how hard it is to put it in.......if its easy, get an autozone one, that way if it goes "easy to change", if its harder like mine, i have to pull the motor out to get to it, kind of a pain..i finally got a high torq starter after the 3rd starter in 6 years seems like they dont like water in them???who knew, you can get a high torq kind like 150.00 i think,i used a lot of grease and sealed up all the edges and havnt had a problem in like 2 years, .....

well im running a 460 with hardin logs an its a pain to pull so i guess im gonna go with a marine one
but is there a big difference in the starter it self like in my truck the starter in on the bottom close to the ground an gets wet it doesnt hurt it right it starts every time an its not a "marine" starter so does it really matter as long as its not sitting in a big puddle of water

I use an Kragen one in my 460 and it is one of the few things that hasn't broken yet   Even after complete submersion and a  terrible oil leak combined with bilge water all over/in it.  Of course now that I mentioned it I'll probably have to replace it after my next time out 

yea i have a hatch on so i'll just use a marine one they should last longer im guessing right ??
