What type of scupper if any does the hull
Have ?

A large ball scupper can let smoke back in Hull in slow or no wake zones... flap scuppers don’t....

Last year I removed my Scupper Flap and had the Versa Plug Max installed. It let smoke in and caused ski to run bad at Low RPM's......... Put flap back on, no issues.

Im not near ski till later today so heres screenshot of back of ski.
More I think about it happens mostly "I think" when rolling slow chest in tray rear of ski fairly underwater.

smoke is backing up at rear and entering your hull via that ball scupper

I take from that its basically not an issue as its only happening when Im coming in to park so who cares at that time??
The only time Ive ever noticed a change in way it ran was after spilling in hull bogged for a few minutes "assuming a bit rich from vapors"

Also add I am considering adding another tube in hoodliner as my hood gets sucked down pretty tight. Could be from hood straps or starving??
