Ok guys, new guy to the boating scene and have a few questions. I have aquired a nice project boat that came with a '75 85hp Evinrude...I checked the compression,all cyls 120+ compression.. I am going to change the lower unit oil..All hoses and wiring looks good.. Anything else you guys think I need to do/check before I fire it up? And from what I have read its a 50:1 oil/gas ratio right..Thanks again everyone....Paul
