At what points do you measure to determine engine shaft length? Thanks Mark

Howdy, Mark.Measure from the part of the mount that fits the top of the transom to the anticavitation plate. Most engines have a code in the model # that gives shaft length. L for Long (20) and X for Xtra-Long (25). Red sky at night. . . JB :) |

Just to clarify, JB is correct about measuring shaft length. It is not precise to the fraction of an inch, but more or less.A 22' will take a single 25" shaft motor BUT 20" shaft for twins. In the "old days" there was regular shaft (15") and long shaft (20"). Then they came out with the extra long shaft (25") in the late 1970's. Now we often here short shaft meaning 15" and sometimes regular meaning 20". It gets confusing and is MUCH better to simply refer to shaft length in inches. We now have shaft lengths of 15", 20", 25" and 30" with abbreviations of R, L, XL, XXL. Just use the numbers. |
