Anyone ever experience random hesitation for 2-3 seconds coming out of the hole? I never have the problem first thing in the morning and the motor runs fine on plane. It always happens after I have ran the boat a while and it has gotten warm, progressively getting worse as the day go on. Most times its after sitting for 30 minutes to an hour on a spot fishing etc. I have taken it to shop several times and nothing can be found. It will not repeat itself in the shop because it has to be warm and under a load. On an average 8 hour day it does it on 50% of the hole shots or so . I run non ethanol fuel and merc opti oil, have tried pulling a plug out of the prop but no change. Grasping for straws, if anyone has seen this I would appreciate any info. Also, at least once a day it will turn over 8-10 times before starting, every other time it starts normal.
