75 Super Sport

[SANTAFE]

Johnson and Evinrude made 3 cylinder 70's and also 75's. What was the difference? I know someone will say 5 horsepower. LOL Are the 75's more desirable?
I recently acquired one on an old Kingfisher, and just wondered.
May just be called a Sport instead of Super Sport. I think the Johnson was called a Stinger.

The exhaust ports are chamfered and the carburetors are jetted one or two sizes bigger.

[SANTAFE]

Not a whole lot of difference.

The 15" motor had a smaller lower unit.

The 75 has less bottom end power than the 70

[SANTAFE]

Does that mean it has more top end power?

[Riverratt]

The porting is designed to run at the higher rpms but not sure if you would notice the 5 hp difference. I just know the 75 we put on my daughters boat is dead on bottom end but comes alive once the bow drops. I was told the 70 would have been a better all around motor for our application.

It might be good on a kneel down rig!

Not a whole lot of difference.

Agree with this, yes different
