I bought a 13X19 prop ($30) used just to test a used 85 140HP that is new to me. Quick History- Blown 92 115HP, got used 140HP, Modified and used my 115 foot and TNT. (never want to thread stainless shift rod again, 3 dies trashed uggghhh) Test ran before TNT with newer 115 foot and bad tach. it litterly jumped out of the water, was scared to go too much as it sounded like too much RPM's. Got a new tach and the new old prop just for testing. Question--- There is a ring on the back of this prop where as my 13X17 has a flange, Why? More important question--- There seems to be a purposely moulded aluminum blocking 1/3 of the thru hub exhaust, Why and should I drill/chip it out for testing? Im going to get a new prop as soon as I know what I need. Any prop Suggestions are very welcomed also. The boat is a 1993 duel console 19' KeyWest. Thanks for any help.
