Mid December, 2002 (salt water temp approx 48 degrees F.)<br /><br />Out for ride. Running approx. ¾ throttle.<br />Engine suddenly lost power and could not maintain plane. Limped home.<br /><br />May, 2003<br /><br />New plugs installed<br />Test ride ran ok. until motor fully warmed up. Lost power again.<br />Checked fuel mixture per service manual - checks out ok.<br /><br />Problem is in the #3 cylinder. I tested all of the cylinders individually by pulling off the other two plug wires. #1&2 ran ok and #3 runs but is intermittent and misses.<br /><br />Did as much diagnostics as I am capable of doing without special testing equipment. They are as follows;<br /><br />1. Switched spark plugs to rule out defective plug - no change<br />2. Switched ignition coil with #1 cylinder to determine if the coil was bad - no change<br /><br />This problem is definately related to a fully warmed up motor and is only affecting the #3 cylinder.<br /><br />Could it be the power pack? Is it something that can go like that and only affect 1 cylinder?<br /><br />Any suggestions as to what else it might be?<br /><br />Thanks in advance for any and all replies.<br /><br />Note: When brand new, the engine (once at operating temp) would stall if turned off for a short time when re-started and put into gear. The problem was reduced once I richened the fuel mix by adjusting the needle screws and had no problem for 2 seasons.
