Hi all,
I have a Mercury 6hp 4-stroke, my2005. This motor also comes in Mariner, Tohatsu and Nissan "costume", afaik.
During last summer, the outboard has been leaking a tiny bit of motor oil. This has gradually worsened to become a pouring oil leak at the end of the season.
I removed the powerhead from the rest of the outboard, and immediately found the leak. It was the oil pan itself that had corroded - nothing wrong with seals or gaskets here.
Have you had the same trouble? The oil pan looks to be made of cast aluminium. A new oil pan is around 230 USD - so I'm aiming at repairing mine. What repair method would you recommend - some chemical metal compound like jb weld, or maybe take the pan to a shop welder? The cast aluminium material looks porous doesn't seem to be ideal for proper tig welding - and everything is pretty tight with gasket surfaces just half an inch away from the hole...
Here's the hole from inside the oil pan:
All the best,
puklars
