V-4 lower unit swap standard to commercial V-4

[mankato]

I have bought a 94 Evinrude 120 V-4 (looper) with bad gears due to water intrusion, but I fished the boat w/owner several times prior to failure and it ran strong, so I bought it as a fixer-upper. Anyone know if a 92 Evinrude commercial V-4 100hp lower unit w/same length shaft will swap? Looks like the gearcase would bolt up exactly, and I know I'd have to re-prop and maybe order a different shift rod, but I didn't know if the difference in 1.86/1 ratio (commercial) would give me trouble since the standard ratio was 2/1.
Thanks... awsome site, just found it!

I'm not sure but you can go to the website below and look at the parts breakdowns. That may help.

If the part number for the mid sections are the same, you may be OK.

8)Thanks for the link guys... it helped me figure out that the commercial gearcase I found for sale has to be a 1995-1997 based on the diagrams, not a 92. The shape of the gearcase and the plastic water intake screen make it a 95-97. Midsections have different part nos, but it still looks like it'll bolt up. Still not sure if it'll work otherwise. So, the new question is; Anyone know if a 95-97 commercial 100 lower will be a suitable replacement for a 94 120 (E120TLER) V-4 - if I re-prop & change shift rods? I sure do like the idea of the beefier gears & such.

Mankato,

In the BRP site, look at the 1992 HP listings. You'll see a 125 HP, that is a COMMERCIAL. Check the cross references on parts there.
