I sanded for a few mins to see how much dust would come out. There is a ton of it. I will mask off the area of the boat and bring out the shop vac to to suck it up. All I have to say they drove that baby in shallow water I can see how large the area was, they must of ran it aground somewhere. The 1 jet pump area is all banged up real bad, they tried to fix it 1/2 assed and didn't want to remove the plastic pump plate so I will remove it and fix itcorrectly. They had to kill a impeller since the one I pulled out was not as bad as the damage was, but the stater veins are all broken on that pump the other pump veins were damaged not as bad. I found 2 very good shape used bronze pumps ($60 each) I am going to put on it instead. Those babys are stonger and take a rock or 2 in them. They are much heavier than the old pumps. Beats paying $225 each for new pumps. I do need new wearrings those the bearing and seals are in good shape on the used pumps.
