This is the first issue with the motor. I run the engine with kid gloves, warm it up every time, no mashing to WOT etc.

I bought the boat in September 2005 and the motor had 32 hours on it. To date I have done the fluid changes and new plugs each year. Plugs bought at the local dealer.

The OLD plugs (still have them) all looked the same, a bit dirty but okay. The new plugs look fine.

Will look at the manual and engine and see if I am up for the fogger test. Got to say this engine is daunting compared to my old Yamaha 90 2-stroke.
