I would suggest that you purchase a good SS prop in a 14 x 19 to use as your
main prop. You will gain speed and acceleration by the improvement in blade
design. Then use the current prop as a spare. Look at the Laser II.

The full throttle RPM was 4500-4700...

Hope that helps

Hey!

I have a 17' Bowrider (fibreglass) and it has a 140HP I/O Engine.
It's
a
1977. I have a 14x19 prop on there right now... I had it up to about
40MPH
and it seems decent at initial acceleration. I'm looking at
purchasing
a
second prop for it as a spare but would like to get one to compliment
the
existing one... I'm looking for suggestions on what to purchase...
Does
it
have to be a 14" diamater? Are there various hub sizes on the props
for
Mercruisers? Any advice would be great!

Thanks,
