Gear case size for prop search on 90spl Johnny

[toddschubert]

J90tslecm any know how to find out what my case size is? I can't get to boat yet to measure it but need a new wheel. Old aluminum must have hit crab trap and is starting to slip. Looking for good used stainless 14"
I'm under powered w the 90 on a 17 sea hunt dual console. Should I maybe go with higher pitch? Got no problem out the hole but could use more speed. Or would this tax motor and should stay at 17 or perhaps less?

Thanks for any help

You have a v4 gearcase. Can't really say w/o knowing what your wot rpms are.

You say you're underpowered... Going to a 19 will lower your rpms, slow your holeshot, and give a top speed about the same, or slower,
