1953 Evinrude Model 7512 Outboard Motor Fleetwin 7.5 HP Saddle Clamp Assembly. Condition is Used.
One of the bolts is frozen in place. I tried to turn it (with a lot of force) and the bolt broke off. I was able to free up the other side just fine. For parts or repair. Ships quick! Thanks for looking.
