How to tell if I bought the correct lower 1995 Oceanpro 150

[crazy charlie]

I bought a spare lower on ebay years ago .I was told at that time that all v6 lowers were interchangeable so I bought the first one that was reasonable with the correct shaft length.I was considering changing it out in the off season and was warned to make sure I have the correct year range.Ugghh ,i may have bought and older one.Any way to easily tell the difference from an older one to the one I need besides putting them side by side????

Shift rod design and spline and driveshaft lengths are the differences....

thanks,I assumed the dshaft length would be same or any long shaft..?? What design difference in shift rod?? Charlie

Transom heights determine whether the motor needs to be long / extra long / double extra long.------And that has nothing to do with the actual length of the part known as the driveshaft.------Different motor configuration and dimensions of block / crankshaft determine the ACTUAL dimension of the driveshaft.---Shift rods differ for the same reasons.
