Ring free question
 

I'm not sure if the previous owner used Ring free in the Yamaha or not. Would anyone know if introdudincing Ring free now would be an issue

I doubt it would make much difference, but what does the can's directions say? :head:

I haven't actually seen the product yet, I was just told by a person with the very same motor as mine about it.. I always like to get the general consensus here first ! I was in a marine supply tonight picking up a float switch and as you can imagine after today's insane amount of rain the bilge pump float switch was mission one !!!

You'll be fine, just start with the initial/shock dose.
