I am restoring a 1965 Hydro Swift with a 1999 115HP Evinrude FICHT. Been sitting for 20 years
Boat is 16 ft but very heavy Glastron hull.
Did the 300 hour service. Compression 121, 125 123, 123, 128.
Ran it on the boat for the first time. Non ethanol fuel, Evinrude 100 oil, Seafoam additive.

People say again and again to run it hard...so I did.
First hour at about 4200...motor seems happy. No smoke. 25 MPH.

Run it fast, they said. Two Strokes like to run at max RPM, they said.

OK, I said. Full throttle was 5600, speed 38 MPH.
After about 8 minutes the RPMs started to creep up: 5700, 5800, 5950 and settled at exactly 6000.
Speed was bang on at 40 MPH an it just stayed this way.

Am I a happy camper? Yep.

Sorry about the extra compression number...either that or I have the only five cylinder 115 in the universe.

Not that the FICHT was a bad concept, it was that random part throttle lean-out.

I friend of mine would perform what he called "The 10,000 r.p.m. Tune-Up", I've also heard it called "The Italian Tune-up".

I little different animal, but I remember buying a '68 Mustang convertible in Atlanta that was down on power and was a bit of a dog. After an oil change and a long day of driving through long grades the rings began to unstick. By the time we got the car into Canada it had more power, the visible blue smoke was gone, and it actually growled out the tailpipes. The previous year of trips under a mile had been hard on it, while the heavy foot on the highway did it a world of good.

Blow The Cobwebs out of it!
