Impros repitching Skat Swirl prop

[cmarch]

I have an overpitched 17-23 Skat Swirl that only runs the boat at 6600 rpm.
The stock impellor runs at 6780 rpm with no tuning changes. Should be running
6940 rpm. I have FA and rejet, can't remember the settings right now, but the
plugs are really black and oily, so I have to tune down the top end.

I sent email to impros yesterday morning for a cost estimate and turn around time,
and have heard nothing back yet. Could impros get this swirl turning 6940,
like I was told it would when I bought it ? What is the best way to contact impros?

Thanks

The *best* way to contact anyone is by picking up the phone during their business hours.

Yea, you’re correct.... I'm too accustomed to the convenience of email!

Tune the boat first. Maybe that prop is fine.

Guess you're reading my tuning thread, too !

I was thinking of trying the swirl again, now that my rpms are up.
With the swirl, I had around 6600.
With the stock (and no tuning changes) I had 6780 rpm.
With tuning on the stock prop, it's at 6850 rpm.

You think if I put the swirl on, I will have the 6600 rpm plus the 70 rpm I got from tuning?

Or do you think the properties of the swirl will
increase the rpm to higher or the same as the stock prop?

Just curious - thanks again

There is only one way to know. Try it.

I started to put the swirl back on last nite,
then realized that I was out of cone oil !

But with how much the stock prop 'woke up'
with the hi screw adjustment, I am pretty confident that the swirl is really going to scream !

I hope to turn at least 6800 with the swirl, but what is really important to me is the acceleration, so hope fully that will be killer!

Thanks again Bill
