Hot start issues on an LT1

Ok So noticed my title was wong...was in my buddie's boat all day with an LT1 I actually have the LTR engine.....Sorry



So latley I have been having some issues witha hot start after a set or 2. I turn off the boat to swap riders and the next start tends to be a little rough. Have to juice the throttle a little a little to get it going.Runs smooth and starts instantly on cold, but the hot start issue came about last year before winterization so just not sure what's going on.

Like I said runs great and purrs, but just a couple hot start times it needs some juice. Anyone with some insight could shoot some things my way.
