I have a rubber duck with 2 Mariner 1983 40HP 2 Stroke

Customer Question

Hi James. I have a rubber duck with 2 Mariner 1983 40HP 2 Stroke engines. I did some body work and general service, including stripping the throttle cables and replaced them again as before. Engine runs beautiful on water earmuffs and in the water. When put into gear I only get 25% rpm. Boat wont plain and under load. Can you help. GEO

Hello my name is ***** ***** I will assist you. It looks like the engine is starving for fuel. To solve your problem you would need to remove the carbs and rebuild them . Ideally open their bowls and let them soak in carb cleaner for a couple of hours . Then blow them using compressed air and rebuild them.

If you have futher questions or need more assistance let me know.

Noel
