Re: iboats does not offer a part is there another one i can use?
The pumps are all the same, the square ones that is (part # 393088 or the sierra equivalent). The difference is with the newer one's they added tabs to the plastic body to aid in reassembly. I used one of the newer kits from OMC on the older pumps, it took 4 tries to get it going but that's because I didn't take pics before I replaced it. Take pictures of the pumps before reassembly, they can go back together with the inlet and outlet pointing in different directions, this is important as putting the lines back on is impossible without the proper direction. Pay attention to where the springs go as well, make a diagram or take pics.
I think Jasper posted the entire pump, I paid only $25 for the OMC kit, CAD dollars of course.
