OK. Here is my problem. Boat starts fine and runs perfectly while on the stand. As soon as I launch it in the water it immediately boggs down and the engine dies. A couple of times, I was able to run a few laps around the lake at super slow "bogg" speed. Yesterday, it planed up a couple of times and ran good for a short lap, then bogged down again and died. I've worked with the high and low settings on the carb and the engine sounds perfect while on the stand. I thought it was a water problem due to a bad auto bailer but I fixed that last night and the problem continued. Any suggestions?
