What would be the effective difference between 13/14 and 14/13 prop on Montauk w OMC 90. Ran 13/14 on Sakonnet w '66 OMC 100 used a lot for skiing. It was great and would really pull em out of the hole. Also worked well for all apps including 100 m/day cruising.

OK, I'll bite. What's a 13/14 and a 14/13 prop?

The 1966 100 horsepower OMC motor had a completely different lower unit than newer 90, different gear ratios, no through hub exhaust on the 1966 etc.. I assume 13/14 and 14/13 mean the diameter and pitch and the 14 pitch might have been right for the 1966 100 hp but you will need a 17 or 19 pitch for a newer 90 OMC.
If the 90 you refer to is also from the 1960's then this advice is worthless.
