Re: New Mercruiser drain and fill plug gaskets
Back in 04 MerCruiser had to use a new fill/drain plug, See Service Bulletin number 2004-02 for the start of needing to go to the new style gasket used in some Situations back then. Now there is A shorter version of the 22-67892A05 fill/ drain plug (new part number 22-67892A06) will be available in the future to fit all applications. Drain Plug 22-67892A06 Now supersedes all other drain plug that will now require you to use the new yellow seals, Part number 26-830749 at a list price of $3.00 for each seal, And only six come in a pack.
If you have the old style gasket that is Blue, orange, black, ect, with an original Drain plug, Then you should still use the old style fiber gasket, That is as long as your serial number calls for the old style gasket to be used. The old gasket part number 12-191832 has now been Superseded to 12-191833 at a retail price of $0.90 each.
Even though I can not find it in writing like I thought I had seen at one time before, I remember them in Mercruiser school talking about the difference between the old style and the new style yellow gaskets has somthing to do with the thickness of the gaskets helping the magnetic end get closer to the gears sets in some applications and further away in other applications so it will not hit, Or getting it closer so it can do it's job and pick up a little bit more if needed due to the new style drain plugs they now have out.
Mercruiser also said they did different colors so that people will not mix the two styles up, Because they could leak.
