I have 23' 2000 Outrage, 225 Merc Optimax. The boat will go 29 Knots
@ 5000RPM. Is this about what I should expect for a speed or will a
different prop pitch make this higher (without suffering at the low
end too much).
What effect does twin engines have for top speed?
Thanks,
Jon
WOT for this motor is 5750 RPM ... top speed wise you may be able to
go down 1 or 2 pitches and go faster. You would lose low end
acceleration ... its always a trade off.
Actually, it's just the opposite. If you drop pitch, you *gain* low end
acceleration. The only reason that you might go faster with a lower pitch
prop is that the lower pitch prop will allow the engine to turn at the
higher RPM
yeah, thats what I meant ... Good catch
