Don't drop the prop

[gofishin]

Sheik, measured the recess O/D of a spare V6 hub size prop I have. It is 110mm.

The prop you show in the photo (~100mm recess O/D) is definitely a V4 hub prop (I'm guessing it's the one off your boat?). Splines on Zukes, Yams and Mercs are the same (15 spline), not sure about Hondas. There are differences in some thrust washers.

If buying new for your boat, just ask for a V4 hub. If used, check the dimensions, or what donk it came off - as the hub size is not stamped on the props (unless you hunt down the details from the model number via Google etc).

Thanks mate appreciate your help.

So put a 14x19 SS to replace the 14x17 originally on it. RPM WOT is about 5800.
Have to say I was expecting a little better performance, as I don't know about top speed (59kmh on new SS prop) but certainly less responsive and slower holeshot with new ss prop.
Should I be expecting a little more RPM than this?
Would the RPM and preformance improve if I lifted the motor?
Thanks again gurus

Did you record some revs, economy and speeds for both props?

...RPM WOT is about 5800. ...Should I be expecting a little more RPM than this?...

What load; people, fuel, gear etc? From memory these donks rev out to 62, don't they? I would probably be looking for more revs.

...Would the RPM and preformance improve if I lifted the motor?...

yes and yes... Normally! But it depends on how high it already is, what sort/type of prop, what condition it is in, pod and type etc, and the type of boat too.

How easy is it to get the current prop to start ventilating? Turns, trim etc?

A 14x18 genuine suzu 3 blade stainless prop sounds like it would be on the money for your set-up.
they perform far better than the solas stuff that's stamped the same size and pitch.
suzuki four strokes can be bitch to get right, especially the 90-115-140 hp range.
