'87 Merc Classic 50 45hp.

As some of you may know, I’ve been having water pump/cooling issues with my Merc. Well come to find out, it’s not the water pump or impeller. I brought it back to the shop that replaced the impeller, to look at it again. The problem is that the water inlet tube, seal, & housing are shot. The later being the problem. they’re not available or not being made. My mechanic searched the sites he knew of & even called Mercury about it.

My question is, does anybody have any ideas or and’87 Merc. or Mariner parts motor laying around??

For some reason, I can’t post the pictures.

The part number is: 79799 (housing, water inlet tube seal)

Thanks in advance for any and all help.
