I am selling a gear case/lower unit extension kit from a big twin 1955 25 hp Johnson (RD-17)(big twin).
I think it will fit single water tube gear cases 1955 -1958 (maybe more years)
Private message me and let’s talk about fitment
Extension has been sand blasted ready for you to paint.
Does not include O-ring 304174 ( I.D. 1/2" x O.D. 5/8" x W 1/16 ")
which I believe goes inside the water tube where the collar is.
$75 or best offer
