Troubleshooting & FAQ
How do I know if this charging coil fits my specific engine?
This coil is confirmed to fit Yamaha 50, 60, and 70 HP 2-stroke outboards from approximately 1984 to 2000. The most reliable method is to cross-reference your old part's OEM number with our listed equivalents (6H3-85520-00, 6H3-85520-00-00). Also, check your model against the compatibility table.
What are the common signs of a failing charging coil?
A faulty charging coil typically results in the engine's battery not charging. Other symptoms can include weak or intermittent spark, engine misfires at certain RPMs, or a complete failure of the electrical system while running.
My E60H engine is newer than 2000. Will this part fit?
While primary compatibility is listed for models up to 2000, some component suppliers indicate that certain E60H models used this part number in later years (up to 2017). Before purchasing for a newer engine, we strongly recommend you visually inspect your current coil and confirm its OEM part number is a match.
Is this a simple "plug-and-play" part?
Yes. This charging coil is engineered as a direct replacement component. It includes the original factory-style electrical connector, so no cutting, splicing, or wire modification is required for installation on a compatible model.
What is the difference between this aftermarket part and an OEM one?
Our aftermarket coil is designed to meet or exceed original factory specifications for electrical output and physical fit. It provides comparable performance and reliability to the OEM part but at a more accessible price.
