I did the ole MC submarine in a 197. Skier popped the handle and put a loop of rope over my head. I put the boat in neutral to get my arms up between the rope and my neck before it strangled me. The rope got all the way in front of the throttle and when it tightened it put the boat in full reverse. The sudden change in speed put the nose under water and about a foot of water came over the windshield. An air pocket in the motor box protected the engine and the boat was running a day later after drying out.
Use those shock tubes!
