OB Shaft length measurement
 

Where do you measure from to determine OB shaft length?

Thanks

Hi Blizzard,Measure from the top of your transom to the bottom of your keel. If it is from 15" to 17" long you'll need to get an outboard with a "short" shaft.(15 " freshwater ,racing,etc.) If it is from 20" to 22" long you'll need our "long" shaft outboard.(20" We as offshore . usually call this one the short) Outboard shafts are measured from the bottom of the engine mounting bracket to the cavitation plate on the lower unit. Generally most boats need either a short or long shaft although some boats require a 25" shaft (ultra-long shaft) outboard.(We call this one the Long shaft) (Most Offshore boats)This is one of the biggest changes when putting a new transom on a Seacraft, or adding a brackett.
