Other "Pre Cut-back?"

[FlightPlanDan]

I sent my 12/17 skat swirl to impros for rehab. The impellor I've been using in the meantime hits nicely. It has a 3mm cut-back. So, I asked impros to do a cut-back on my prop.

I rec'd the invoice via e-mail and there was no charge for the cut-back. Questioned via e-mail, and the reply was ...

"your prop is already cut-back 6mm. Remove the spacer to get one more mm"

I purchased the prop brand new approx 5 years ago.
Is this the way skat makes 'em? Perhaps the skat I'm currently using is older?

This is in NO WAY a slam of any kind to impros. Dealing with them was a positive experience!

Just curious.

Thanx,
Dan

Skat can be a bit inconsistent. I their pitch isn't always what the numbers on the impeller says. Sometimes they cut the impeller back too far. When my new impeller for my mag pump was ordered, they cut it so far back that an additional spacer had to be used.

that more or less confirms what Dave said!

No, yours was an unusual one at a -6mm set back already so I could see charging you for the set up for 1mm. You can remove your spacer and get the last 1mm for free.
Thank you for your business

If this is the last spacer between i just want to forewarn to make sure the impeller thread is greased nicely !!

I have all mine removed...

I think I'll leave the spacer in there. But thanx for the tip. (I always grease the snot out of it hoping it will be easier to get off next time)

I'm installing a brand new wear ring at the same time. I think that will make a bigger difference than 1mm! Got 7 years out of the OEM! Can't complain.

Maybe I should have asked impros to verify the pitch! If it hits, it don't matter....but would be good to know!
