20SF w/150 Evinrude Top-End

[Bigshrimpin]

I had a 1999 150 Ficht on my 20 MA and I could barely break 40mph. Those 60 degree OMC motors seem to have a LOT of low end power, but don't breathe very well at high RPM. When I switched over to a 1981 Merc V225 with a 19 Mirage Plus and I could break 50mph solo easily.

If you want to go fast . . . find a 1986 or 1987 Evinrude 225 2.7L (bridgeport) or a 2.5L Mercury 200 (1991/2 Mercury 200hp 2.5L had the 7 petal fronts like the promax).

Older 1991 and earlier Mercury 2.4L 200's are a good compromise (great power to weight ratio) 83 and later 2.4L motors had fingerports, all 200's and most 175's were chrome bore.
