Ok...I have two problems with my engine...first, my engine stalls out when you first load into the water and take off with it. The first couple of times I took it to the lake it worked fine, but the last two or three this problem as happened. After a few minutes at slower speeds it warms up and then seems to perform fine, however about the same time as this happened, if I have been running boat at probabley half throttle or more my engine sputters and shakes for several seconds ( like ten ) before it dies. It sounds like it is flooding out or something. It startes back up fine and seems to run fine, but does it almost everytime, unless I drive at slow rpm for 10 min or so. Any suggestions would be very appreciated!
