The motor start well. After approximately 15 to 30 minutes of utilisation such as water ski, the motor stop (like if there was no more gaz) while running at high speed (the last two time, there was someone doing water ski behind). Once this happen, the motor could either not start or start with the choke. The repair man said the motor was drown (the two cylinders got full of gaz) but does not know why this happen. Could this be due to the type pf gaz (I chance gaz from regular octane (87) to super (94 I believe). I also check if the cause could be due to vapor lock but there was no air in the gaz tube.
