The boat started to surge like I was pushing the throttle back and forth in a cycle at low to mid rpm. Seem to happen around 20 mph...it didnt seem to affect the performance a lot but the you could hear the engine surging in and out in a perfect cycle. It didnt do it a low rpm 5-10 mph and it didnt seem as bad or was non-existent at faster speeds. The engine wasn't hot and all the guages read where they should be. Same thing the next day. The first time out no problem, second time out when it was warmed up same problem again.
The boat is a hot rod on water and I think she is telling me she likes to go fast...but I kind of need it to run well at slower speeds.
Any ideas? Does it sound like a fuel issue...maybe the pump or choke? Or does it sound more like an ignition issue. I did not change the points or condenser this year.
Any help would be much appreciated. Its good to be back on here again!!!!!
Thank you.
