Picked up a 1968 evinrude 3hp for cheap. seems to mostly complete. Missing a few items. Anyone have a good lead on the engine cowl seal? Both Crowley marine and marineone list it as unavailable. Further searches show unavailable most small motors until you hit the 25-35 OMC motors. My question is will this seal work if I shorten it ? Looks like several of these motors in the 3-6 hp range for a few yrs have a similar seal.
