Sheafer Posted May 23 Report Share Posted May 23 Hey guys am in the process of repowering my RF21 and have few options I know generally we use a 25 inch leg on the RF21 but going to a 20 inch leg opens up the world of 300r and pro XS engines with semi surface running props and boxes meaning more speed and shallower running Has any one here tried to run a 20 inch leg on a RF21? I am thinking its doable with the jack plate and as far as i understand it the older pathfinders and RF21 all used the 20 inch leg engines Hoping for some guidance Cheers Sheafer 1 Quote Link to comment Share on other sites More sharing options...
Lap it Up Posted May 24 Report Share Posted May 24 It can be done. Just need to calculate the correct amount of setback. If I were to guess, I’d say 10” setback. Quote Link to comment Share on other sites More sharing options...
Sheafer Posted May 26 Author Report Share Posted May 26 Thankyou mate i was thinking the same and have ordered a 8 inch spacer from T&H to convert my factory jack plate to a 14 inch so 4 inched more setback than factory Hoping this will work 2 Quote Link to comment Share on other sites More sharing options...
