85 horse power motor has ran great for the 4 years that I'ved owned it. The problem began with the motor cutting out after opening the throttle. The boat would almost come up to speed then the motor would cut out. Restart and it would run really rough and then even out. Seems like it is not getting enough fuel. I replaced the primer bulb and did away with the quick disconnect. Problem stayed the same I figured it was time to try and rebuild the fuel pump. I took fuel pump off the motor and dismantled it. Some of the parts in the fuel pump are missing. There is no gasket (h) no booster spring (f) and no booster spring retainer (e). The letters in parenthesis are from the diagram in the force service manual. How is it possible that this has ran for the last 4 years. It doesn't look like these parts come with a rebuild kit. Will they be hard to find ?
