My first I/O need tips & info

[TacomaTom]

Some of you may have seen my other threads so for you guys ill just say that between the new starter and some cables i got her running fine.
But running it out of the water scares me. I want to make sure i am not gonna damage anything.

Ive been told that what i have is an OMC stringer. It has a connection on the port side for a hose. As long as i have water running to that am i ok? Do i plug that when im in the water?
Also how does the engine stay cool with no fan? And the radiator is so small. Does the engine or outdrive get cooled with seawater aswell?

Like i said i am new to the I/O stuff and dont want to mess anything up.

For reference my boat is a 1976 19' Thompson with a ford 302 (that i paid $250 BTW And it came with a brand new Die Hard Platinum $250 Battery haha what a steal. So far anyway.

Yes you should cap that fitting when in the water. Also you should have the drive all the way down when running under any load.

There is no radiator, the water from the drive cools the engine and exhaust manifolds.

If its not a radiator what is tha tank of water sitting on the top front of the engine?

it's the marine equivalent of a radiator. called a heat exchanger. same basic cooling principle involved except the heat exchanger uses water to cool instead of air.

raw water cooled = no heat exchanger and cooling is done directly by the water your boating in.

fresh water cooled = heat exchanger. has anti freeze in it to cool the block and maybe more. cooling is done by convection via raw water that pumps through the heat exchanger cooling off the anti freeze.

So i still need to use the hose on the stern drive and cap it when in water right?

yes

that pic is weird- the engine is running - water coming out the exhaust, but then I can see the flushing adapter on the port side with no hose attached?

magic?

The water is coming from the drain. This boat had been sitting outside under a tree for at least 2 years so it had alot of leaves and stuff in it.
