Hello. First post. Searched but couldn’t find a post regarding my exact situation. I have an 89 Maxum 2000 stern drive. Previous owner swapped in a mercruiser 5.0. Anyways. I have only owned this boat for this season. It has been working well with the exception of an exhaust leak which I fixed. I also readjusted the shift cables when I did the exhaust leak as I had to remove them anyways. I had been running fine since. This last weekend I took it out and all was well until on my way back to the boat launch. I took off and just as it was coming to plane it fell on its face. It was barely moving and I limped it back to the ramp. When i hit the accelerator I saw the carb butterfly move and it would rev just fine but the prop would not spin any faster. But the prop was spinning. As if I lost almost all gears. Reverse worked as well but again only just barely. Any ideas? Any help or insight would be much appreciated.
