Hi everyone. I'm new to this forum and I hope I'm doing this correct. I have a 1994 Pro V 150. I need some help with loss of power out of the hole. I noticed some minor surging at top speed of 54 mph. The engine started cutting in and out and losing about 5 mph and then going back up. the boat sat for about a month and when I took it back out it lost power and went down to only 20 mph. Wen I tried to stop it and gunned it from a stand still it was very sluggish and wouldn't get up to speed. Took it out of the water took the carbs off and rebuilt them. Put it back in and it ran good for about two hours and then same thing all over. Thought it maybe coils. Tried testing them ( ohms test and the old pull plug wire off engine ). Couldn't really see any difference. Bought one new coil and swapped each one out at a time and no luck. Can anyone give me some suggestions what to look for next?
Regards, Toni
