Measure straight down from the top of the transom edge to the keel. Do not lay the tape measure against the transom. 


That will tel you the transome height then post the complete engine model here.


Anyone familiar with boat rigging can also just look at the boat and know, too

The Evinrude ETEC has 15 and 20" shaft models in the 15HO - 30 hp models. The 60 - 90 hp would be 20 or 25" shafts.
