Hey guys, I have a 96 Mariner Magnum EFI 2.5L, serial # is OG337303. I did a tune up on it this weekend. New fuel filter, inline oil filter, plugs and impeller rebuild kit. I fired it up in the driveway with the muffs to make sure everything was good. I noticed whenever I put it in gear, either fwrd or reverse the prop won't spin. The boat does have a hot foot. I have to rev it considerably to get the prop to spin. This is the first time I start it in the driveway but I know before when on the water just putting it in gear it would cruise about 3.5mph. So that means something's not right.... right? Any suggestions before i have to tear it back down? Not sure what I'm missing here.
