Just replaced the impellor on my 78 Merc 50 hp seriel no 9206843 and it now pumps water fine BUT as I was taking the lower case off a rubber seal dropped from somewhere onto the floor. On inspection it was exactly the same seal as the top seal that fits on the drive shaft of which there are 2 but the shaft already had the 2 seals still on the shaft ?
The seals are shown in the manual I have but I cannot find them on the onlne parts lists anywhere not that it needs them but just to see if those seals are used on another part of the unit anywhere.
Because this is the first time the lower unit has been removed since new I can only conclude it was put somewhere in the housing during manufacture unless it is actually used on something else apart from the top of the drive shaft ?
