Hi,i own a seadoo rxp 07 155hp,and i instaled riva intake grate,solas impeller 11/19,riva pump wedge,rd air filter,and get rid of the resonator by installing an inox pipe.Now i m thinking to change the plastic pump into an aluminium.I would like to know if i have to swap to another impeller for exaple an 12/20 in order to reclaim the total tuning by improving accelaration and top end

Why do you want to replace the entire pump? A much more affordable and quicker alternative would be to replace the stock plastic impeller liner with our Stainless Steel Replacement Wear Ring.



Its durable stainless steel construction resists debris damage and saltwater corrosion. Plus, it provides increased durability and performance through precision machined clearance between the wear ring and impeller.
