Paul make sure you have the updated harmonic balancer for this engine as well assuming yours is a 4 stroke . They are known bombs if the factory ones in it yet !
Wondering if you were able to fix your problem. I have the exact same model and appears the same rectifier. Battery not charging. My alternator reading on my starboard engine never goes above 12. My port goes all the way up to 14. Trying to decide if it’s the stator or the rectifier
