prop /gearcase question

[Maximerc]

I am looking at a prop for sale .. it says its 15 spline that is correct for my 1984 V 6 150 hp engine .. but it says its a small gearcase then it says V4 or XR4

Would this fit ??? Ideas ??

Re: prop /gearcase question

Small gearcases are 4-1/4". Large gearcases are 4-3/4" Some early V6 motors came with small gearcases. Measure yours to be sure.
