86 force 125 wont run in neutral

[nabularach]

O.k I wll start from the beginning. A few weeks ago I overheated my motor, I sucked up sand and it blocked my water passage. I cleared it out but the thermostat was broken so I put it back together without the thermostat until I can get a new one. I ran the boat for most of the day ( No Problems). When I went to restart the boat it wouldnt start in neutral so I had to give it full throttle to get it to start but then it would stall when I put it back into neutral. This boat is fairly new to me and i am at the tail end of my first tank of gas so I was thinking I may have a blocked fuel filter but I wont be near the boat to check it until next weekend. When I start the boat at full throttle it should be screaming but it sounds more like a high idle. Any thoughts on this problem.

Thanks

Too many possabilities.

Start with the basics to narrow it down.

Check for spark on all plugs.
Check the compression.
