I have a 1972 Johnson 65 Stinger that has been a faithful motor since it was new. This summer I have been experiencing problems with the motor cutting out (shutting off) while running full throttle for a minute or two...... can anyone help me diagnose this problem ?? The motor runs fine at low and medium throttle........ it only cuts out when at full throttle. Please advise what needs to be done or how to fix this problem.
