Please also supply Paul with your water temperature and fresh or salt. Because water density plays a role in proper pitch the USCG has been known to change props mid ocean when running from the Hawaii to Seattle.
My best advice has always been to let a local specialty prop shop pick the propeller but just in case that's not practical please post your prop information for Paul.

I hope that it will be possible to repitch our existing 12 x 8 prop to use the additional power. Questions for Universal 5411 powered C27 owners: What diameter and pitch of prop are you using? If possible, what is the rear ratio of your tranny? In our case the Petter has a 2:1 tranny, the Universal has 1.8:1 gears. How well does your system work? ie What's your max speed and rpm? Does anyone know what dimension prop was factory installed on Universal 5411 equipped C27s? Thanks in advance, Paul Meyer Fredericton, New Brunswick Canada ------------------------------------------------------------------------------ Looking for the perfect gift? Give the gift of Flickr!
