Looking for GO Nitro Engine Spare Parts

--------------------------------------------------------------------------------

I recently purchased a Pursuit nitro Boat with a GO 25 engine in it. I bought this for my Son's birthday. Unfortunately whilst running in the motor I blew the conrod and piston. I have searched everywhere on the Net but cannot find the suitable parts, can anyone help?

I have a Rossi 5-port which seems similar in conrod size but piston is .21 size, could this GO engine be a clone of another?

Cheers Matt
