    Questions regarding differences in pump

    Hey guys. I have an 03 GTX SC. It has the plastic pump which has seen better days. I picked up an aluminum pump which I believe is from a later year RXP or RXT. It came with an aluminum wear ring and prop.

    I am pretty the RXP/T had a larger diameter prop with a larger driveshaft.

    Just want to be sure everything else is the same and will work if I swap over my prop/wear ring from my 185hp pump.

    As long as the aluminum pump is from an 04-08 RXP/RXT it will work great, just change the impeller, wear ring and replace the front oil seal on the pump. I'd also use a new reducer, the two o-rings at the cone, new grease and neo pump seal when installing back on. You should also use smaller diameter flat washers and using the newer bronze lock nuts is good practice too.
