Hello all. Got a problem and was hoping to get some feedback. Took my boat to the lake this past weekend and noticed the motor running funny. Ran great on the trailer before I took it up there, real responsive, sounded crisp, etc. Got to the lake, dropped it in and fired it up. Sound fine at idol but as soon as you gave it gas it sounded like the timing was off or "misfiring". Though it could have been fuel so I checked float levels and neddle and seats and they were all fine. Also had 7 lbs pressure whole time so it was good there. Got it back to the house. Checked all the spark plugs and they all have fire. Havent changed anything since the last time it was at the lake two weeks ago and it ran great. Any ideas?
