took the boat out today for it's first run, and everything was fine till I decided to let her go. It's starts to take off no probem, bow in the air, and then when it hit's 3000rpm, just about to start it's plane out, the engine just bogs, like we hit something, and quits. At first we thought we did hit something, but after trying again same thing, but this time it wouldn't start. I just put in 2 new batteries, and yet it tryed to turn over like they were both dead. After get a boost, it still took almost 5 minutes before it finally kicked in and started. We checked spark, and had it, so it seems to be a fuel related problem I guess. I did put in a new water seperator this spring. The only thing I did different this year for winterizing was to put flogging oil in the carb. <br />I'm going to check out the spark plugs tomorrow, but I would think a bad plug would just cause chugging, not kill the engine all together. We then ran it for over 2 hours at 2000rpm without a glitch. I then tried full out again, and it died everytime at 3000rpm, and I restarted everytime with no problem. <br />Does any one have an experience with this problem, or any suggestions, thanks!!!!!!!!!!!!!!
