Re: Stainless Steel Prop - Johnson 1977 70 HP
williamettejeff, I guess there are still afew around...most of the OMC built ones are gone (I hope)and MWC has continued on with only the cupped version for this application (13 spline), and I suppose there could be some of there old stock out there on a shelf yet...but remember this, if we have power trim, we stay with the same pitch, even though it's cupped, and in some cases, if a guy has a little time to listen and try some of these things like lifting the engine as far as the prop will allow, we can them go to a higher tech prop and gain even more.<br />Even though we start with a 17 uncupped, we may end-up with a 19 cupped at even higher RPM...this is where things start to really get efficient, and the person experimenting usually ends up saying "Man...I wish I had done this along time ago"....
