Outboard Motor Grease Fiitings

[BrocLuno]

So high pressure grease fittings are Zerks. But there seem to be low pressure fitting that look like about a 1/4" bump, round on top with a hole in it... I take it there is some kind of greaser with a plastic cup end that will just push grease into these?

Please name the fittings and what do I use to apply grease?

Some of these look to be cast right in to various components and just drilled as part of the build ...

Lincoln 5803. You'll need to buy a 1/8"NPT grease fitting though.

Nope, not the one. It might work, but it ain't right. The one I saw at the outboard shop was a metal extension tube with a plastic end the cups the "nub" around the outside so it centers ...

Pic? I've seen grease ports/holes before but not very often!

maybe you are looking for this pump: http://www.mercruiserparts.com/30500-gun-grease
works great even on regular zerks, and I have only seen regulare zerks on my mariner, mercury and johnson outboards.
You fit a plastic tube to the pump, like merc 24c grease

I think you have taken push type grease gun http://www.sturdy-tools.com/product/push-type-grease-guns/.
Now you need to purchase apt nozzle for it.
