Apologies for the delayed response. It was the 159mm.

Thanks for the reply Jetboy
If you could humor me a bit further on this subject I would appreciate it.
Upon disassembly I discovered that my boat came with a 161 mm dia pump arrangement and apparently was unique to this boat.(g series boat)
Needing a sleeve and prop, and due to a total lack of support by Scarab and Rotax I was unable to identify replacement pitch etc... let alone a source for 161 mm parts I elected to downsize to the 159 mm pump and guessed with a Solas ss sleeve and SRX-CD-14/19 prop
Overall I am happy with the results as prior to change out max speed was 33-35 @ 7800 rpm and after 40-41 @ 7800 rpm (clean water, avg temp day in MN, single adult male bear driving) Hops out of the hole well and @ speed in a few moments
Speed was verified with GPS and aligned with the scarab instruments
In my long winded way what is your speed and rpm under similar conditions, and are you able to hit the 8000 rpm max

Thanks

Excellent report back. Glad it worked out out. The 14/19 was a good choice as well. Your numbers and gains are right on par. 40- 41mph at 7800rpm is right where I am with little wife and myself aboard on glassy back Bay evening in OC MD.

Kudos to the change out and gains!

Hey guys just both a 2017 scarab 195 been having issues with low rpms and low speed initially was 5600k rpms Replaced wear ring, replace impeller 161mm with solas 13/18, rebuild supercharger max rpms now 6900k any help will be appreciated engine runs perfect

I believe that your engine is capable of safely operating at 8000 rpm.
I may be off here but there are built in computer permissives that can keep the engine from achieving this max rpm
It's my understanding that if one exceeds the service intervals there is a built in governor that restricts maximum rpm
The service needs to be done and the service warning cleared in the computer to allow max rpm operation again

Hope this helps
