1989 80hp (3 cyl)Merc<br /><br />I recently went through my carbs and just prior to reassembly noticed that each kit I ordered ("7211-1 86-up Carb Kit w/Needle L3-L4 Mercury OE#1395-9595-1") contained two cover gaskets and only one mounting gasket. Of course, I needed two mounting gaskets and only one cover gasket each...What's up with that? Went to NAPA and some automotive thermostat gaskets matched the mounting gaskets pretty well...used them between the cover plate and carbs. <br /><br />Next, I ordered an impeller kit. Got to inspecting the plastic water pump base and found several of the silicone seals looked sketchy. In aligning things for reassembly, I noticed one of the gaskets in the kit didn't align with some of the ports in the plastic base plate...checked the old gasket and whoever had been in there before me must have gotten the same rebuild kit--didn't look like a good seal at all. Apparantly Merc used two different bases: one was aluminum, one plastic with silicone seals. The plastic one mates directly with the metal impeller base plate...ie, no gasket.<br /><br />Well, I ordered the "complete" water pump kit (RL 12094/OEM 46-43024A6) and will see what I get...but I mated the plastic part to the base plate and installed it all, only without loctite or the RTV sealant...idled it in the driveway and if it peed like a racehorse before, it pees like a racehorse on steroids now!<br /><br />However, water wells up the hole in the cavitation plate in front of the shifter shaft, and sprays/gurgles out of the horizontal slots aft of the cavitation plate, so I'm reluctant to take it out until I get a new (and hopefully correct) pump kit in. <br /><br />Has anybody else had problems finding the proper water pump gaskets for these things? The Seloc manual indicates that there are indeed two styles, but none of the application charts I've run across seem to indicate this.
