Will do!! I changed all plugs today, so they are all new now, they were a bit oily and looked old?
This is a response I got from Iboats. I explained all just like I have done here, but I think this guy is wrong as I had this issue long before I went trolling for Tuna. I am going again by th way Wednesday!!

You simply have an oil overload.
When this occurs again, immediately pull the plugs and take a hard look at them. I'd be willing to bet that they are seriously oiled to the point that they will NOT fire under a heavy load such as put on the motor at 4500 RPM.
There is also an amount of pure oil in the recirc system, patiently waiting for engine speed to increase sufficiently to get it airborne and burnt off and let the spark plugs burn clean enough for the engine to get up to full power again.
The factory oiling systems lighten the oil mixture at low engine speeds to prevent this oil overload and hesitant throttle after long periods of idling and/or trolling.
Possible cures are;
1. install a small trolling motor and NOT idle the big motor
2. install spark plugs one-step hotter than the factory specified plugs (also, if piston clearance is adequate, change from surface gap to standard electrode or extended electrode plug)
3. if carb'd, readjust idle mixture to leanest idle possible and still not have any hesitation on rapid acceleration in gear.
