I just recently purchased a 2003 Islandia.
Was running fine until I pulled a tube. Boat could barely get over 25mph and would drop to 20 mph immediately on turning. Throttle maxed out. After about 15 minutes the motor start missing. More severe when I would hit waves. Dropped tube and drove around and it would start missing again after 20-30 seconds at high RPMs. ran and started great as long as it was lower speeds, under 20 mph.
