engine tuner or equvilent

[tav]

been buying tuner on line can't seem to find it in my area but
is there another product i can use in place of the tuner that works as good?

[ChampioNman]

A&S (Boat Works) boats should have it, but if you can't find it Mercury's Power tune works well too.

I need to get some more as well. I've always had the can to screw onto the shrader valve. Does Mercury offer that? Or would I just begin spraying it directly into my 6 carbs?

Depending on the can and spray nozzle type you might be able to swap the shrader valve hose right onto the different can. That was the only difference between the 2 version sold by Evinrude.

I'm going straight into the carbs
