Engine has been acting weird lately. A month ago, when i would be in idle then slowly rev up to get on plane, at about 2000 rpms it would start surging, then if i throttled it pretty good it would stop and run full speed just fine. Problem never happened again. Then this last weekend, it started doing the exact same thing but this time it happened more often. But sometimes it wouldn't surge at all. Also when it would surge, if i throttled it, it would make a terrible sound. Then i would shut it off and restart and then it wouldn't make that noise anymore. I am thoroughly confused as to what is happening. Can anyone maybe identify the problem? Any suggestions?
It also is vibrating alot more when im going slow, 3-5 mph.

Have you changed out the fuel pump diaphragms?
