Inboard Boat Engine

I always thought that if the engine went out on an inboard boat that I could replace it with a car engine. Someone told me the other day just during a general discussion that that wasn't possible because the engine ran in the opposite direction. Is this true?

No, but you don't want to put a car engine in as it is not marinized. Marine engines are designed to work in enclosed spaces..aka they are built no to catch fire.

Also they are designed to work under constant load and to resist corrosion in a humid environment. You could do it but the car engine would probably have a short life.

Removing a 170hp Mercruiser boat engine . Re power with a 90hp Yamaha (2 Stroke)outboard. Using a 30inch setback possitive boyancy bracket ...

I am thinking of buying a 16ft lund boat that has a 4cyl inboard engine and heard that they are terribly underpowered. I have no knowledge of inboard engine's I have always used outboards. I would like to hear from someone who know's more than me and also what horsepower this engine would produce

You need more info about the boat.How much does it weigh? What size engine is it? What pitch is the prop? And are you intending to pull skiers or not?

i have a 350 chev set up for salt water but now want to return it to the original configuration without the chev water pump and heat exchanger, and just rely purely on the impeller pump picking up from under the boat, and thru the engine, back into the exhaust
sorry, didnt explain myself very well. The boat is now only run in fresh water, not salt water so the heat exchanger is no longer necessary, and generally runs warmer with the exchanged than without

Marine engines, as well as automotive engines are, cooled by circulating water thru the engine block. Marine engines are unique in that there are two different types of cooling systems. The standard raw water system, and the fresh water (commonly known as the closed) cooling system.

I do believe more information is needed here to answer your question... but I will try.
What water do you want to drain? Do you have an "open" or "enclosed" water cooling system? Did your boat sink? Or, do you live in the north and need to "winterize" your boat?
If you have an "open" water cooling system, there is no water to drain... the system sucks water in from the lake you are boating on, it runs through your engine and blows out (generally in holes just below your exhaust. If you have an "enclosed system" (similiar to the system on your car - with is mostly common in salt water craft) you will need to drain it from bottom of your radiator... as you would your car... If you live in the north where boats are generally removed from the water and winterized... most boaters I know, (my self included) drain their enclosed system at the bottom of the radiator, and then simply remove the "freeze plug". On the other hand - if in fact your boat sank, and was recovered... most (good) Marinas or salvage yards will take care of this automatically. It is critical that the water is immediately replaced with a special grade oil to prevent rust, oxidation, and damage from being submerged. and they are best capable of handling this... At my marina, I have watched them do this, and they have a high pressure machine that pumps oil into the engine and forces the water out in such a way that prevents air from getting inside. this, not only helps prevent oxidation, it insures they indeed get all the water out... they use these devices on outboards that have been submerged as well.

I agree the oil filled electric seem to work pretty good. I also have a ceramic space heater with tip-over switch. But I installed 20 amp outlets and breakers for these heaters. I don use the regular boat receptacle circuits. And I made sure all my shore power CABLES ARE IN GOOD CONDITION.
