My questions is, when I take it out, will it be possible to get it
looking clean again?

You may never get it back to the condition it was before, but you should be
able to get it fairly clean.

Also, do most of you keep the Outboard engine submerged when in a marina?

I have a pontoon houseboat with outboards. I have the hulls painted below
the water line with an epoxy barrier coat covered by an antifouling paint.
This protects the hulls fairly well. I raise the outboards clear of the
water to keep them from being eaten away.

You should have sacrificial anodes ("zincs") installed at several places on
your hulls and outboard to assure that you don't suffer from electrolysis or
galvanic corrosion. This is even more critical if your hulls are aluminum,
and absolutely essential if you connect the boat to shore power.

Your outboard would have been equipped with anodes but you should check and
make sure that they are still intact. I would recommend two more (large
ones) on each hull. If your hulls plane then it may not be feasible to have
one anyplace except on the back of the pontoons.
