Have a 1991 90hp johnson. Are there some points on the leg/lower unit to measure to determine the driveshaft length. Looking for a replacement and want to get something the correct length. Thanks.

Yes, Thos.

Measure from the underside of the transom clamp to the anti-ventilation plate. About 20" is a long shaft, about 25" is Xtralong.

You can also find that info in the model number. Look for an "L" or an "X" in the model number.

Oh, and Welcome to iboats. :)
