So excited to get back on the water soon!
Last couple times out last year started to get a new popping noise at half throttle or so and later noticed a drop in max RPM!
Tested with a timing light and had no spark at #1 cylinder.
Pulled the coil and tested and found it to be bad.
Found a used one on Ebay for $18.00 (New one around $130)
Installed, tested and I have spark!!!!
Have been too busy with other projects and Summer fun times to hit the lake!
Will post results when I do get the chance!
