what speed should my rib achieve?

[xpertski]

hey all, just wondering what speed my humber ocean pro 6.3m should reach, with a 140hp suzuki and standard prop? currently i cant top 39 knots, and im sure i heard in a test report that the same boat with 115hp suzuki made 40 knots........anything wrong?

Have a friend with a 6.5 Humber and a 140 Suzuki, top speed 38 kts.

Solent 6.5 w/ 150 Merc Opti = 50 knots.

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

[Rodan]

Humber 8m + 225 Opti - 38Kts too.... will be working on this as I would have thought more kts possible...

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:
