Re: Sears Ted Williams 7.5 HP
Hi Rob, Well I might as well toss in a guess. I could not find your model # on any of my lists, yet. From info I do have model#s that begin with 571, were made by West Bend (that's not you), model#s that begin with 574 were made by McCulloch (formerly Scott) (formerly Scott-Atwater). So between you stating that you have two empellers and that the model# begins with 574, I am going to say you have a McCulloch. These models feature a self bailer for the boat. The reason for two empellers, one for cooling and one for bilge. This was a left over from Scott-Atwater's famous bail-o-matic. Points sets, condencers, and EMPELLERS are available after market from Sierra. Napa auto parts deals these parts from there marine catolog. My guess is you need Napa part# 18-3009 (replaces #73055) empeller for a 7.5hp 1960-69. Hopefully you have one of the many great Napa dealers near you. There are a few around my area that ain't cuttin it. The part# I gave is for one empeller only, not a kit.
