1996 336 SR1 525SC Sea water pumps

[ur2slo]

Hey all,
Need some help with replacement pumps. Everything I'm finding says the pump design and hoses are not stock mercury. My inlet and outlet are horizontal and the hoses fit around the motor mount . All the pump housings I'm finding are rear entry and the existing hoses , which are preformed won't work. The rear housing is cast with integral inlet and outlet and two 3/8" pipe plug bosses on both. Casting #'s 821707 0 and 004531.
I'm looking for two pumps, assy's or otherwise and one set of hoses for the port engine, since I had to bastardize them to get home. Any help would greatly be appreciated. BTW, any one heading to the Thunderboat Regatta in San Diego in Sept? Sure would like to meet up with some of ya!
