removing and replacing upper crank seal on a 1999 50 HP Mercury..

[Bondar]

I will be attempting to change the upper crank shaft seal tomorrow on my 1999 Mercury 50hp 4 stroke. Anything I should look out for? Seems fairly straight forward. Just looking for someone who may have done this before

Thanks

The seals under you water impeller?

 

In your lower unit?

Before you touch it find a service manual online. I can tell you merc 2.5 litre blocks require you to split the block halves and possibly pull the pistons/rods for that repair.

Thanks Hirk, it ended up being another issue all fixed up now

Glad to hear you got it fixed
