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.
Rc boat with water cooled 26cc 2 stroke engine. Not far to go now,with only prop,drive train and servos still in the post. Home made steering ...
If the cooling system is in good working order, what possible way is there for it to over heat?
The "flywheel fan" turns at the same speed as the engine. If the engine is heavily loaded it slows down, so it's not cooling as well and at the same time generating more heat. See Answer above.
Great for radiators, oil cooler, transmission coolers & more!

What are some valid reasons as to why this fact is true?
In my experience that's not always the case in fact I'd say they are more noisy. But it's a different pitch. You can put a water cooled engine in an engine room and insulate it for sound, but an air cooled needs to be have large air ducts, and it's difficult to isolate the sound.
It (the water) is pushed to the recirculating pump on the front of the motor. It is distributed thru the engine just like the anti-freeze in your car. Then it is released down the exhaust log where it collects the heat from the exhaust(which travels in it's own tube). Finally the exhaust and the coolant water from the river are blown out the back of the boat after being lifted above the water level - which helps keep outside water from running backward up the exhaust.
edit; The fresh water system has been installer in gas engines and was popular with Volvo when they went to the aluminum heads on their 131. But most american cast iron boat motors are from industrial blocks and have very heavy exhaust manifolds so you can run hot salt water thru them for years without a failure. Call up your local boat dealer and ask how many boats in his yard have "freshwater cooling". But if you have an "electrolysis" problem- all bets are off and nothing will live long.

moncler 2010 salenew_-Boat Part Basics You Should Know_544mens ...
If you’re thinking about purchasing a boat, but you’re not that savvy when it comes to marine and automotive mechanics, it might be helpful to learn about a few parts. If you experience problems with your new boat or yacht, you might have a harder time pinpointing the issue than you might with your land vehicle. Just as an automotive engine needs a cooling system for the engine to stay cool enough to drive, moncler 2010 sale , a boat needs marine engine fuel coolers and marine engine oil coolers to keep your boat running properly. These cooling systems work, both in cars and boats, by circulating water through the engine cooling systems. There are two main types of cooling systems, mens moncler jackets , raw water and fresh water. Raw water cooling systems draw water in from the outside of the boat and run it through the engine’s cooling system. The only long-term problem with these types of marine engine fuel coolers is when you use salt water for coolant. Over time the salt in the water corrodes the engine and blocks the exhaust manifolds which will cost you a lot of money to replace. A rusty engine will not run well on the water and won’t last long at all. These types of cooling systems are simpler and often less costly, they tend not to last as long as fresh water systems. Fresh water marine cooling systems utilize a marine engine heat exchanger that acts like a car radiator. The coolant goes through one side of the engines cooling system and the raw water goes through the other side and comes out the exhaust. A fresh water marine system is a more reliable way to cool your boat engine, because it lasts longer. Even though the types of engine cooling systems may not be of concern to you, you will still need to know your options if you ever need to replace this piece of equipment. No matter the brand of engine you have on your boat, you can usually find a company that will have the right kind of cooling system to fit your specific engine. Internet auction websites, moncler jackets , manufacturer websites, and discount part websites are the best ways to get the lowest price for the replacement part you need. Once you’ve found the part you need, you may want to consider taking your boat and the part to a boat mechanic. This will save you more money than if you buy the part directly from the boat mechanic. If you’re really daring, you can find forums and websites that will tell you exactly how to install and replace parts of your boats. If you’re a do-it-yourself kind of person, moncler uk salenew_-Live Cricket Scoremoncler shop , this may be the most inexpensive option, but if you’re not so handy, you might cause yourself more harm than good by trying to do everything yourself.
