i dont know what caused it he was out fishing and the piston blew then it wouldnt budge so he had to use a 1 and a half outboard gator motor to get a 18 foot aluminum boat halfway across the lake.
thank god i wasnt there. any way thank you for the help and if it aint to much trouble can you find the price for a fuel pump for the same motor.

thank you:

"Shawn..... I checked my remaining stock, don't have any of those pistons left. I do however have two (2) of the std ring sets, two (2) of the .020 O/S ring sets, and one (1) of the .030 O/S ring sets, discounting them to $20 per set should you be interested. [email protected]
