I have a buddy who has a 185 and i helped him change the pump, i didnt think it was that bad, at least compared to my 882. what we had to do was unthread the pump a bit from the valve and it came right out, there is also a nut on the threads between the pump and valve. its not an easy job but can be done. at least on the 185 you can see the pump to work in it. on my 882 its buried under the gas tank, to change mine i had to go into the bilge up to my waist and i still couldnt see it, had to do the whole job blind. he installed a mayfair cartidge type pump so next time there will be no hassles, i did the same with mine. when you get it out gat a 750gph one, the more flow the better imho.
