Re: 1986 90 hp Trim and Tilt
I can you this much here.....<br /><br />The Mercury current part number for that pump assembly is 826729A4 which is superceded from 99186. It's sold only as a pump assembly, $1049 from you friendly local Merc dealer (FLMD). (there are carbon brush and spring kits available though)<br /><br />If yours is not rusted through and still working it might be time to pull it, wire brush it, and slather on some protective paint.<br /><br />-W
