I've got a 28p x 14 3/4 4 blade Spinelli prop that I use to run on my Eliminator 22 Eagle xp with a 502 Mag MPI. Boat ran 78 mph with this prop. I no longer have the boat and still have the prop if anyone is interested. Paid big bucks brand new in 1999, will let go for significantly less??? This is a complete custom prop that's flawless small shaft solid hub...
