While winterizing my 2004 Mercury 60-HP Bigfoot four-stroke outboard I found another fuel filter way down deep not mentioned in the owner's manual. It's under a black cover so you can't see it. However, you also cannot get at it. Same goes for the bottom spark plug, which is just above that filter.

Has anybody changed the hidden filter and the bottom spark plug? If so, what did you have to remove to access them?

Thanks,

Steve

Don`t know about your motor Steve, but I remember on the old inline Mercs I used an open end wrench to remove the unaccesable bottom spark plug.

Thanks for the tip, Binkie.

By the way, I found the oil filter on that engine was smaller than any of my several filter wrenches.

Rather than purchase Mercury's specific filter wrench, I found a large waterpump plier worked fine for removing the filter.

On most outboards there is a cowling which can be removed to improve access to the lower part of the power head. Often this cowling is just held on with four machine screws. Removing it may make servicing the power head easier.

My bet is with Jim on removing a cowling.

On what motors can you remove the lower cowling without removing the powerhead first. It would be a good idea.Rich
