I have three 5hp Johnson sea horse td-20's and one 2.5hp johnson sea horse hd-25. Can anyone tell me the part numbers for the proper test props / wheels to use for these 1947 - 1950 outboards?

Re: Test Prop Part Numbers

Howdy Hayshaker!<br /><br />Don't believe there was ever test props made for these small engine. I usually crank them up in the test tank with the prop they have on them. If you have access to a ramp or pond, just put them on the back of a boat and crank them up.<br /><br />This is really the best way to tune them in anyway.....on the back of a boat underway. I would avoid trying to tune them in with just a garbage can as a test tank....just not enough volumn of water there.
