Jason, you have a good memory. Yes, he lives in Iowa and was trying the 2-blade bronze prop I sold him. If I remember correctly, the motor clamps were not tight and the boat got out of control and went into a pattern of violent movements. Threw him overboard. He and the boat were okay, but it sure scared him. He is the one the runs a 1500XS Merc jacked up on a Glastron Contender that does about 80 MPH. He is active on the Mercury Outpost site and rebuilds Mercury in-line sixes.
I was thrown out of a 11 foot racing runabout at 35 MPH that hit a wave at an angle and the boat continued close to the swimming area.
