has anyone tried to polish their pump viens?

[dv8rxp]

I took some pretty good damage to my whole pump setup this past weekend. While I was grinding down my pump vein area I was thinking of polishing the whole thing. Anyone think its a good/bad idea? I don't think it would hurt to try it.

Go for it Greg, I think they call it a port&polish? I'll be out there in the morning around 9 and I'll be launching at the boat launch.

I think I'll get it done tonite so I can test it in the morning

I know it isn't my rxp, but I did it to my sons stock brass pump on his 96xp and I noticed a better holeshole and it felt like it stayed hooked up better.

Will that be called trueing the pump???

"Blueprinting the Pump" I sharpened all the veins took out all the imperfections and polished. Saw no gains with the stock impeller at that time. This doesn't mean it wouldn't work with a different setup.

i hear from the great minds that its a waste of time, i did it on my xpl way back when and saw nothing at all, the rxp veins are actuallt alot smoother than the older brass pumps, some people have seen gains by roughing up the bottom of their hulls, so maybe brp left teh castings rough for a reason

Round off the leading edge of the pump veins and sharpen the trailing edge. Water will flow over them more efficently...or at least that is what happens with outboard motor skegs. Should apply in this case too (?)
