Go .21 motor question

[Derrick Stewart]

I have included a photo of a GO .21 engine and was wondering if anyone can tell me if the is a newer version of the GO engine series 5 port or 7 port

Thanks

look through the exhaust port. What do you see? One big wide port, or one larger port, and two smaller satellite ports, one on each side?

I cant check to see as I have not purchased the engine yet and the owner knows nothing about the engine except that it is new

I did notice the this motor says GO on the side as where the ones I seen on the thread from the distributer has just a G on it

So is this an older version?

This is the current version GO marine motor.

Either the 5 port or 7 port engines are equivalent in performance. No real advantage for either over the other.

It Looks like a current one. But it all depends what timing the sleeve has and who sold it. When I was selling them. I could order different sleeves in them if I wanted.
