Um, is this true for all 'flips'? We just got our 1989 Waverunners and had kids flip them for a cpl minutes while they were trying to learn to balance on them. I did not see any water in the engine compartment (did check that after the flip). I also looked for plugs, but could not find any. Anyone know where I'd draing these if I did see water in the compartment? Thanks in advance
