1985 Mastercraft S&S

[VintageS&S]

I just bought a 1985 Mastercraft S&S and need advice on my propeller.
The stamping on my prop reads: "OJ 13 IN CUP A"
There is a stamping on the side reading: "OJohnson T"
Anyone know the prop I have and what size would have came with the boat when it was new?
Most props I have seen have a # for the dia, and another for the pitch or cup.

Call Acme or Oj. Both have great customer service and can recommend the correct prop for your boat.

Probably a 13x13

Is a 13 X 13, the date code T is from late 80's. Give me a call and we can discuss a new prop.
