Had on the river and had just a little over 3/4 throttle and just died out took a min to get restarted for some reason key would not start it had to jump cylinder to get it to fire back up then started making a weird noise took each plug wire off one at a time and confirmed number three was not hitting but was getting fired any ideas what this may or may not be it does not have coils it has a distributor thanks in advance

Compression test would be the first thing.---Post your numbers.-----Have you installed a new water pump impeller at least every 3 years ?
