So yesterday I installed the 42's and SS wear ring and pitched my prop 2mm. I put everything back together today minus the nozzle. I decided to fire it up and it stayed started for a about a couple of seconds, when i heard some loud rubbing from the prop/wear ring (I THINK) and then it suddenly shut off. Then of course the battery died so its on the charger for now. I guess tomorrow I will pull the pump and check the driveshaft spline for damage and then maybe spray some lube on the impellor to free it up around the ring. Any other suggestions would thanks.
