.I learn something new everyday.Well in this case rake was something I had ignored 
as I hadn't a clue.So armed with se7en's info,I hit google,took a wee while for the alcohol free grey matter to absorb the info.The theory of pitch and slip I had read plenty about but it's the first time I paid attention to this rake side of it.I knew floaters was the newer ADI ignition but not about the extra transfer port in the newer 80HP.I'll need to reread all the stuff I have backed up on this bloody computer.One sore head coming up and I haven't been near a beer or whiskey in a month
Mind you it's unlikely I'll ever be using a s/s prop and worrying about too much/little rake,unless I get one for Christmas
So my conclusion,is that I need greater aft rake on my prop if my boat is bow heavy and tilt trim is unable to raise it for more top end with all other variables of engine size,height,max/min rpms and prop pitch taken into account.I'm not being facetious,just curious as to being on the right track or not
