SR 5.4 + 90hp Yam K series prop size

Having the 17 pith one and its working OK, WOT about 5500 RPM. Anyone tested a 19 pitch prop with this set-up? Will buy a spare one so might be a good idea to test another size ?
Cheers

Yep, the 19" is the best prop for solo/2 up use. I've used 17,19 and 21" props on mine and the 19 the best by far.

OK, thanks, that's good information. Will try to source a reasonably priced 19 somewhere.
