I just bought an after market SS prop 13 3/8 x 15 pitch. My other alum. prop is 13 1/2(I think) x 13. the diamater really isn't the issue with contact but the depth of the throat of the prop is.
The alum. prop is 6 1/4 from the front of the prop to the back edge. My new SS is 6 3/4. That half inch throws the prop blades too far out and they make contact (I didn't run it to find out I just turned the prop) with the trim tab.
Four questions
1: Does the added 1/2 of throat cause any problems with balance on the lower unit?
2: Can I trim off the 1/4 inch or so from the trim tab to get blade clearance
3: Is there a trim tab that off sets forward so I can get clearance with out having to "customize" mine.
4: I ran the motor yesterday with the trim tab off and it didn't seem to run any different. Is the trim tab just a anod or does it serve a purpose?
