1. Anyone know what year my 9.9 Mariner is, serial #08731873

2. I bought this motor used, about 4 years ago. The motor looks like it's new, and ran great the first few years, even though
I only use it for 2 weeks every fall. Last year I encountered a problem with it. It starts fine, and runs fine, but when I'm cruising accross the lake at full throttle, the engine suddenly goes from full to idle speed/rpm even while the throttle is still wide open, if I throttle back to a lower setting and run for a few minutes, it starts running normal again, and I can run it at full throttle again until it cuts out again. I put fuel stabilizer in every year, and run the carb dry, before putting the motor away for the season. I only use fresh fuel every year, but feel that it could be fuel delivery problem. I also put new plugs in before the problem started, but swapped them out, and still encountered the problem. Is it possible that I damaged a spark plug wire? Any suggestions that you can offer would be very much appreciated.
Thanks,
Big Bull
