My dad volunteered me to help his friend with his 5hp Hiawatha outboard. It's a 2cycle, 2cylinder engine. I spent some time looking at it and decided I'm not digging in until I know what's inside. I did some searching and this particular engines blood lines include being sold by Montgomery Wards, and made by another company. From my knowledge it runs, but not so well and is very hard to start. Any details on what needs to be done to clean the carb, and adjust it would be very greatly appreciated.

Also how is this cooled? From my knowledge it should be liquid like all other boat engines, but I can't find any intakes or places where the water would exit. It does not have a fan on the fly wheel either.

Thanks!!

Just above the lower gear housing, there should be water inlet holes on one or both sides. The coolant water is expelled with the exhaust. It is definitely a water cooled unit.

Thanks, is there any knowledge on the card on this? how to take it apart and what to be careful of? Another question is how is this turned off? there's no kill wire to anywhere, only a carving in the handle that says off, or something else.

Throttle is more controlled by ignition timing than the carb throttle opening. I'm not exactly sure, but shutdown might be just by retarding the throttle till it can't run. The throttling arm moves the whole ignition plate, and also opens/closes the carb butterfly as it moves. I figure it has a single carb for both cylinders? As to shop manuals, you'll need to do some google digging. Here is some info:

that explains the oversized, connected to every thing throttle. There is just one carb for both cylinders.

If it just has a dirty carb and needs some tuning up, why not run it in a barrel with a heavy dose of Berrymans in the fuel. Then change the plugs and see what you've got. It looks old enough to have points, so you might have to clean and adjust those too. In fact, that could be the whole problem.

I had an old Mercury with no apparent kill switch. The choke was the kill system of choice.

Be sure it pumps water through the cooling system when you start it up. There's usually a telltale hole that pees water below the power head and above the water line so you can see it working. A common problem is a bad water pump impeller or clogged passages.
