Here is a  photo of her on her first sled,  A 1966 Johnson Skee-Horse.

My Mother kept her Johnson sled stock for all of two weeks!!!

She had purchased it at a marina in Jackson Michigan and the guy who owned the marina fabricated an intake manifold that would accept a carb off a 20HP Mercury Hurricane outboard along with linkage to accept cable operation which boosted its speed to about 45MPH. 

She would just lie in wait for other Johnson and Evinrude sleds on a nearby lake just to blow their skis off.  She bought a matching sleigh  ( cutter ) to pull behind to carry ice fishing equipment or whatever.  

She kept it about 5 years before she bought her first Yamaha a SL 396...
If memory serves me, and the final sled was the dreaded GPX 433.   

Mother passed away 5 years ago and I told her if they had sleds where she was going that she could have the fastest one.
