Commercial Outboard Motor.

[panorama69]

Hello, I have a 1985 model Johnson 120hp VRO outboard motor. The model is AJ120TLCO and serial number is 710693 I was told from some of my friends that this motor maybe a commercial type motor, are you able to confirm with me if this is correct.<br />Also I have a Carribbean Commodore 21 foot fiberglass half cabin boat with a 15x19 propeller, I have a stainless steel prop I like to use and the size is 13.3/8"x17" could I possibly use or is the Diameter to small.<br />Thanks Darren.

Re: Commercial Outboard Motor.

Welcome!!<br /><br />Does your motor have a single fuel (fuel / oil) pump?<br /><br />That motor has a V6 style (not a true V6 unit) gearcase that takes the larger props. I'd bet the 13 3/8" prop wont fit. Count the splines. If the count is the same, it should go on. If it does I'd bet you'll be disappointed losing that much diameter.
