Johnson 4 hp serial number

[mbobone]

I have a 4hp Johnson with the following serial Number BJ4RCCS. Can anyone tell me if it is a short or long shaft unit?

Re: Johnson 4 hp serial number

BJ4RCCS indicates it's a shortshaft. You should measure between the crux (or inside top) of the transom clamps and the flate plate directly above the prop (anti-ventilation or cavitation plate). 15+" measured here is a shortshaft, 20+" would be a longshaft.<br />Nice picture of the measurement, courtesy of rickdb1boat:<br /><br />

<br /><br />B- Belgium built<br />J- Johnson<br />4- 4hp<br />R- Rope Start<br />(an 'L' here too would indicate a longshaft)<br />CC- 1988<br />S- meaningless run code.
