Well I’ve never had one but from other discussions on this board the big problem with them is the coil is always bad. A replacement is $125.00 to $140.00 so anyone that knows this wont want to give you much for it. Some have tried modifying the John Deere pony coil ($50.00) but the conversion is complicated and for some it wasn’t successful. Here are some links on the coil issue. Tubs.

A "Boathouse Repair" is one thats done without having tools or the skills to do it properly.
