I have an 85 Ts6M and have been pretty satisfied.

The only downfalls are the Top end (40mph with water temps in the 70s) and the floor.

All of us with older Supras know how poor the drainage is on these boats. If you waterski you don't want to drain any water anywhere but the center of the boat... And I thought these boats were designed to get wet

I can't complain too much though, the floor lasted 20 yrs. After a new floor install last winter, the boat is about ready for a new owner. I need something a little faster for barefooting.
