Howdy All,
Quick question. If an 5.7 Mecruiser (GM) engine is at 3000 RPM what RPM is the outdrive (alpha 1/1) turning at with a 1:47 ratio?
It's been a long time since I posted here. With Irene in 2011 & Sandy in 2012 it's been a long tough time getting things back to normal (semi)! I hope all effected have since recovered also!
I enjoyed meeting some of you fellow Club Sea Ray members at the Zacks Bay rendezvous a few years ago. Now it's time to relocate & retire to Myrtle Beach, SC. We are looking forward to meeting the people of, and boating with the MB Power Squadron.
Thanks to all,
Rich & Deb
