Looks like they can be done in Canada
Located in Canada. Save international shipping fees, duties, taxes and hassle at the border.

A couple of years ago I checked into using the Simon flash on a 60 hp Mercury 4 stroke.
The cost was $650.00 US plus shipping.
Gain was 5 hp with improved acceleration.
Too costly.
But, maybe less now with these folks.
Might give that motor the little extra punch it needs to run with the OMC in T750.

FOR THE 40 HP PEOPLE!
They could flash a 40 hp 4 cylinder to 60 hp!!

There is a post on that other members only internet, aka FB, showing a before/after dyno plot of a Yamaha F70 having been tuned.. 70hp before, 80hp after.

Quote:

After spending a bit of time on this engine and setting it up to run on 91/95 octane, we have gained some good power and torque throughout the entire RPM range. This engine has picked up 20% gains in power and 18% gains in torque @ 4700 rpm!

The Yamaha 70 is the same powerhead at the Mercury 50-60hp Yamaha added their own touch.

If this is accurate this is good news for the Mercury Formula 60 hp 4 stroke.

I don't think so.

Maybe. Isn't the head different on the Yamaha F70 compared to the F60 and Merc 60?
