SE 116 Maximum Prop Diameter??

['93 2655 Ciera]

I just ordered a Mercury Alpha 4 four blade prop for my boat, which has an SE 116 drive. I previously had a 14 1/2" diameter 3 blade prop and the clearance was pretty close. The Alpha 4 has a diameter of 15", and now I am wondering if a 15" diameter prop will even fit. Will it? What is the maximum diameter prop that I can use with the SE 116 without the blades hitting the anti-cavitation plate?
Thanks!

You could get a 16" diameter prop to fit without hitting the cav plate. The problem is you will hit the trim tab anode unless you cut it down or switch to the flat anode.

Ok, thanks... I have the flat anode, so I guess I will be fine.
