  How to tell a if you have a 60° Johnson-Evinrude V4 or V6 Outboard: 
60° V4 & V6 motors were introduced in the mid-90's. All 60° motors were loop-charged models with the vapor tank system. The top-view motor covers were roughly rectangular in shape and had vents along the rear sides. Pumps # 06-150 (V6) & 04-90 (V4) below must be used for these.
60 degree cover
60 degree cover side
The 90° V4 & V6 motors had a fairly distinct triangular top-view profile. The V4 & V6 Crossflow motors had this design, as did larger V6 90° Looper motors 200 - 300 HP.
Except for a few of the XP perfromance models, these covers usually had no side vents.

  The way the pump is mounted will also tell you: 




90 degree
Stand-alone bracket mounted
(Many V4 Crossflow motors mount to front air box instead).
Several designs were used for brackets but the general mounting scheme is the same.
ALL 90° VRO mount like this

60 degree
ALL 60° VRO are Mounted to a vapor recovery tank as illustrated
