I recently had to have prop shaft replaced. Doubt that this has anything to do with problem.<br /><br />Motor starts fine. I advance the throtle and after going about 100-150 yards the motor quits. It resarts with no problem. Advance the power and the same thing happens. I put it slightly above idle and it might run for 300-500 yards and quits again.<br />I have had it at dealor/service 3 different times and they still haven't found problem. They cannot get it to fail with the 'ears' for cooling at the shop, but when they take it to the lake they experience the same problem that I do. Would appreciate any feedback.
