had 1979 70 hp mercury with a 18 inch chopper on my voodoo. I am puttin a 1974 70 hp johnson stinger on it the shaft is 13 spline like the merc put the shaft is longer and stepped at the back. Do I need a new prop or do I get it rehubed. do I need a bigger prop because of the size of the gearcase.
thanks I need all the help I can get.

You should be able to have the prop rehubbed for the stinger. Run the prop you have, see what you think of it. See where your rpm and top speed are at, how it handles, how it carries the boat, then make prop changes from there.

Good advise above.

You may be able to fit your prop to the OMC with washers, etc., for testing. (maybe not)

My motor is a different size, but I obtained a custom thrust washer that allows me to run OMC props on the Merc.

thanks guys for all your help. been busy working to answer sooner

You have a very good source of info in Suds, one of the fastest v-bottoms in canada. He's a busy guy, but great to talk to if you get a chance. Pm me if you like....
