Why no oil filter on 4 stroke outboards?

Why wouldn't they put oil filters on 4 stroke outboards? Any speculation on this.

I thought all 4 strokes had oil filters. What motor are you talking about?

My 4-stroke has an oil filter, and I'm pretty sure about this because I just spilled oil all over my engine while changing it:)

There is no filter in my Suzuki. I don't see a reference to one in the manual.
My 6hp 4 stroke Tohatsu doesn't have one either.
man I hope I didn't miss something. these are my babies

Mark, there should be a filter there--starboard side of the engine best I remember. I recently changed the oil in my 140. You have to remove the side covers below the cowl. Use a Suzuki filter. I tried one from CarQuest and it matched the #s. It worked but couldn't re-install the side covers--filter a fraction too tall. I bought an extra Suzi oil filter for next time. Lesson learned---stick with the manufacturer's products, they fit.

Mines on the port side, I have to remove the side cover to get to it as well.

I see that I have to replace it. I'll look again.

Mark, you're halfway there. Now remover the side covers on the leg(?). Probably about 6 screws. Then you'll see it.

It's the section below the cowl gasket. It splits centerline best I remember.

Well,
I've taken all these screws off and cant get the cowl off. Time to purchase a manual. I'm worried things will go boing. Damn replacing a filter should be simple!! You'd think the owner's manual would cover this.
I think I can live without a new filter for a while.

Mark, you can do it on your own. If you removed the screws from the lower cowl, it will split apart and expose the oil filter below the exhaust header manifold. This may help:
