That should help with the soda pop theory.

Nothing like your exhaust being an intake manifold too. LOL.

This .gif is great as a demonstration (2 stroke exhaust) of what I'm trying to say . LOL.

Never the less the point is there are exhausts that are better suited for a particular need.

When I raced in the IKF nationals I carried over 20 pipes which is what sucked about 2 cycle.

However there are ways to tune 4 cycles for a particular application in a similar kind of way.

Examples would be:

Running wide open (circle track)

Accelerating (drag)

Mudding ( keeping water out of a submerged exhaust)

Marine (reversion)

Sounds simplistic, but those are only 4 that do not call for the same design

Exhaust valves on 2 stroke sleds work well.

A Tundra can tow a 42 ft fountain
You MUST have a diesel truck to tow anything bigger than 26 ft.
A bravo based drive is good for 800+ HP as long as "you are easy on the stix"...
What cam should I use to prevent reversion?
Brand X will always be better than brand Y
Your boat is worth 20% less than what you are selling it for
Baja owners drive vette's, Cigarette owners drive Porsche's
Skanks are better than hoe's...

Try hitting it with a hammer. It's already broke, what's the worst that could happen? It may just start working again.

Those are called outboards . There was, however, a speedboat built awhile back which used six 2-stroke Mercury powerheads mounted in-board.

An electric bilge blower if piped to the carb will add up to 25% more HP to the motors.
