Hi all new to the form.......Just bought a 2002 Wellcraft with a 2002 Johnson 115, have had the boat out a few times with no issues. But the last time out an once before it ran great for the 1st hour, then after sitting for a bit while the kids fished and swam. I started it back up and when I went to full throttle to get up on plane the motor would rev up to 3800 then drop off to 3400 RPM... I kept trying to cruise along at 2500 RPM then push it to get up on plane and nothing, wouldn't go pass 3500rmp.... I looked at the plugs, wires and spark, all looked good, after doing this took boat out it ran like a top no issues, then went out this pass weekend and the issue should back up, ran good then after stopping at a beach it wouldn't go pass 3500 RMP........ Anyones' help would be great.... Thanks in advance....
