"I began experiencing a problem with my boat this year, and have spent more time and money than I can afford attempting to diagnose and repair the problem. I am hoping that this will help.
Here are the symptoms: I accelerate to full throttle and after about three minutes the engine begins to slow. If allowed to continue, the motor will shut down. It will restart but seems to miss in at least two cylinders. If allowed to cool, it will run well again, until I open it up again.
These are the things we have done in attempting to repair it. Compression tested and was good in three and acceptable in the other. Spark tested and is good now. Replaced all of the following parts hoping to find the culprit: Stator, Power Box, 2 coils, water pump impellor, rebuilt fuel pump. Removed and thouroughly cleaned all the carbs. Replaced the inline fuel filter. Pumped out boats gas tank and cleaned. Replaced spark plugs. Replaced fuel line quick connect. Checked all fuel line fittings for air leaks.
It simply just keeps losing cylinders under heavy load. Then runs rough and misses until completely cooled.
Can anyone help me????????"
