Pratical use of automobile engines in boats ? what are the differences for rust, corrosion protection? - propeller protection
I always dream of crazy ideas, and I'd support a new generation of high performance personal watercraft - the tube pan. I want a V-8 put in long Seadoo boats and used only a single propeller shaft at the rear of the engine to get involved, perhaps a simple clutch mechanism / Disconnect power electric axis.
Anyway, all this said, I know that the boats of the type of motor car use, but the use of special water cooled exhaust manifolds, etc. What do other Boaterizing a car engine for a marine "engine"? A special tricks to prevent corrosion of dissimilar metals in the engine? If you decide to cool a car engine right boat with water manifolds, as long as no other engine is modified to use mods? Of course, a boat style and cooling system is installed \\ \\ are \\ \\ \\ \\ \\ \\ u0026lt, duh. "So, with the exception of heating, cooling and exhaust manifold, what else should be changed to the rule?

A label sailors and a sharp rise in the price. Although there are specialized marine engines that use special alloys to prevent corrosion (ie, Atomic 4 Diesel westerbreke) ships most of its cheap, basic car-ski, can, for economic reasons (to use knowledge will not save a ship engine a $ 10,000 new Bayliner brand new for $ 8995) sold
Traversed to your question, how long you last depends on the quality of water, salt, sand, silt, algae changes the whole life. Most boats are dying from neglect than anything else.
Even if you can a radiator cooling air in the same boat (as) it is easier to use underwater. I suggest a heat exchanger, you can add this type of corrosion inhibitors in antifreeze and water through the engine.
Boats with a dry or wet exhaust leak. Dry gas is like a car, no water through the exhaust manifold. The exhaust pipe is hot, are not usually vented above the ship, but as the envelope. They are generally used in motor racing style boats say (trawl pip striaghtfrequently) A wet exhaust, exhaust manifold is cooled with water and are usually on the exhaust pipe a few inches sparked from the exhaust manifold. This allows you to use a rubber hose to the exhaust vent through the fuselage.
The Coast Guard has a flash suppressor carburetor engine, a piece of window screen to meet this requirement, however. Nothing says must use a carburetor, fuel injection system works equally well on a boat.
As for the gearbox (transmission) Caviate Helix typical effieciency loose, long before Redline motor. As a rule, provides a translation is used to adjust an optimal adjustment rpm with optimum speed. Most boats use a golf game in helix diameter is, if it is the beginning or the good acceleration. Accessories variable does not exist, but expensive.
In addition, marine engines are not in the left multi-boat engine accessories change the address on the gearbox.
Why heat exchanger cooling water in the lake? And escape the cold. Radator file a car on a lake of seawater flow through? Aluminum will not intended for this purpose, but from copper and brass. Manifolds can water break where nobody can see and run the water into the exhaust valve opens, the engine stopped. Modern 400 hp LS-2 Corvette engine 400 Nm is a real rocket motor with a saltwater lake ot years for cold storage will be no problem. PT Boats were silent for nearly silent engines.
They should be more than just a simple coupling mechanism due to the fact that marine engines are generally run much higher speeds, the engine characteristic. If you do something like one of the smallest cars, boats, and a V-8, it would give too much power. You need not be in your seat belt, just to keep his place. Somewhat smaller than a Honda K22 would be better. It should reach the milestone of 10K RPM.
Marine engines are designed to work all day at 4200 rpm. Passenger car engines are not the cars are devices allow a change in revolutions per minute, they can not call the shots. constant pressure. Marine engines have metal timing gears and chains, warehouse and heavy freezing OUT bronze bushes, heavy with the camera .. a 350 CI 260 HP Marine is is usually a car or truck usually CV best180 big difference in performance ... Can a motor boat on a vehicle, but do not start the engine of your car on a boat. Unless you love to hear it !!!!! Go Bang!
Go ahead ...
Imagine a circuit heat exchanger for cooling sealed ... Antifreeze in a water bath. You need to sink into the block and the axis of the control unit of galvanic corrosion. Several exchange the car for a marine variety (eBay), the pumping of water into the exhaust to leave the boat. Do not flame / spark something without sparks begin tower / generator / power. Make sure it is good, the air intake vents. There is also a good idea to put the engine compartment before a start to unravel. Make sure that you do not bite much HP on the other side of the support. AY!
Consider a jet age Berkley heated whirlpool and a unit for the right to block bolt GM developed.
Berkley had a 455 in an old Oldsmobile into a cigarette Labaronne (21ft) and simply the best! Good luck.
In addition, evidence-ignition starter and alternator, and a fire in the air supply must
