Is it possible to flip over your average runabout? I have a 1986 Regal medallion 18' 140hp 17pitch and it seems no matter what I do water doesn't even enter the boat no matter how hard I handle it at any speed. My friend has a 21' 1990 Maxum with an L-drive 120hp 17pitch and It almost seems like his was going to flip people almost jumped out but it just bobbed back out of the water. Is it possible to sink these boats going at insane 40mph speeds or is it the slow speed massive whirlpool donuts that we need to be watching out for?? Please help I need to know if I'm going to sink! Should I be operating as a lesser throttle??
