Warren: In late 02' I aquired a 4 cylinder, 4 stoke EFI, 40hp Mercury with the standard gearcase and a 60 ECU. At the time, I was running some fairly hot 60hp Merc 2 strokes, my best was 113hp at the propshaft. The unit was sent to me to attempt to destroy under NORMAL conditions, kind of a prototype type thing..... I have run this motor since late 02. It is on it's thrid boat, my old 2 strokes have all been sold. I would not run a 2 stroke if you gve it to me, I would keep my old slow 4 stroke. It is now on an Edge 1556. Since 02, everywhere this motor goes, it goes at 6249rpm, throttle to the floor. I change the oil once a year, have changed the water pump impeller once, and changed spark plugs last year. It still burns zero oil between changes. So fa it has not been passed by anyone's stock 60 hpoutboard, 2,4 8,10, or 12 stroke. This is the absolute first pass with this motor on the new Edge boat......
It now looks like this:
