The boat is a 16′ Thundercraft, running a 13 1/2 x 15 pitch prop, but I think the boat data is irrevelant at this point. The motor will start and idle well, it revs up in neutral but the moment it goes in gear it stalls. It stalls when put into forward or reverse. The other day I got it to stay going at 3 mph but if I increase the throttle it stalled. I sprayed some deep creep into the carbs and it ran a little faster so I figured it could be the carbs. I took them apart and cleaned them but it’s worse again. Now it stalls as soon as I put it in gear.
