Re: Merc laser11 prop hub conversion to johnson ?
You need to check the diameter of the gearcase. A lot of the V4 motors have the larger V6 gearcase (4-3/4"). A 1985 IL 6 Merc 115 will have the smaller gearcase (4-3/8").
if the gearcases are the same, look up your prop and find the J/E hub and buy it. if the prop is a one piece pressed in hub, it can be converted by drilling out some of the spline and using a modified thrust hub and spacer.
