I would like to know if the lower unit I have is a one tube design water system or a two tube design. Also I know this came off of a 28 hp motor. I would like to know if this will fit other years and other horsepower motors.

1 tube design for engines without thermostat. It should fit '57-'58 35hp engines (Without Thermostat for the '58!), '56 30hp engines, '62-'64 28hp engines and '65-'71 33hp engines. It will fit '70+ 40hp commercial engines but I don't recommend it because it uses an older bearing arrangement not found in the 40hp lower units.
