Engine wont gain revs!
Took my thundercat out today. started fine on muffs in the drive & started in the water. headed off & went up to half throttle, the 3/4 throttle and all fine. Running alot smoother with the new spark plugs. Then went to take it upto full throttle & it wouldnt gain revs and started to run really lumpy!?
Took it back to shore, put another set of used plugs in and had same problem. then when it was running i touched the coils (with dry hands) and i got a large shock through the rubber spark cap. So im not sure if the coils are going?
Anybody got anyideas?
