Super Jet Flush connection?

[Ricky_Rich]

I have just bought a Yamaha SuperJet 650 from 1990. This one have Coffman exhaust, but no flush connection.
I need to install one to be able to pour antifreeze in the engine.
I found this picture online, is this the right way to install a flush on a Coffman?

Yeah that's the correct location. Ensure the engine is running prior to adding water or antifreeze.

Thank's! Would be too sad if anything gets damaged during the cold winter.

I'm in MN (gets cold) and never winterize my 2 strokes. I don't leave any of my epoxied engines out in the cold though.

Just run them a few times prior to storage.

Thank's for the advice. I think I will add some antifreeze to be om the safe side.
