My rincon is snorkeled. All vent lines, everything etc. is snorkeled to top of my snorkel when I’m under for more then 1:30 seconds it seems like it looses power to the wheels, oh and I’m hammering it also. Full throttle! Lol, But once I’m out of the water WAH-LLAAA it’ll pull a wheelie! I fabbed up an exaust tip at my job and put it on. Do you think this could be causing it? Maybe it has to much back pressure???
