Those Suzy strokers are slow, heavy old girls. Better to ditch that for a proper engine. An Opti perhaps.

thank

yeah traditionally the four strokes are heavy but the 140 is lihter than most, it weighs i think 186kg. maybe a different prop would help things. did actually consider an opti at the time, but had previously had a suzuki and thought it was an amazing engine, which the 140 i have is too, but, maybe could do with a bit more grunt!

Is that 50 knots or 50 mph?

Bruce seems to have had Farfetched at nearly 50 knots, but with Kevin from Solent driving:

Farfetched - Sea Trial
