How does a Marine alternator work?
Moving a wire through a magnetic field creates current flow in the wire. The alternator generates electricity by rotating a magnetic field in the rotor around a circle of stationary copper windings called the stator. The amperage created is determined by the strength of the magnetic field.
How many amps does a boat alternator put out?
At 1,200 engine rpm, the typical 90-amp alternator produces between 25 and 40 amps of output. At the same rpm, the Wakespeed alternator delivers roughly 115 amps. While Wakespeed targets inboard ski and wakeboard boats, boosting amperage can help marine engines in other boat types too, within reason.
How much does a boat alternator cost?
Labor costs are estimated between $284 and $359 while parts are priced between $386 and $479.
Is there a difference between a car alternator in a boat alternator?
Industrial alternator applications require continuous-duty, high-output alternators built to last while operating safely. This means that marine alternators must be self-cooling at high loads or have an additional cooling subsystem. Marine alternators also comply with strict safety specifications not required of cars.
Is a boat alternator AC or DC?
A dynamo is a DC device, both when used to generate electricity or as an electric motor. There is no terminal from which you can take AC, the commutator is an integral part of the device. An alternator can be a self contained unit without diodes or field control circuitry and still be recognized as an alternator.
How long do marine alternators last?
In general, you can expect alternators to last about 6-10 years, or about 80,000-150,000 miles.
What is the difference in a marine alternator?
Should I paint Marine alternator?
alternators should not be painted, even to slow corrosion. However nice they look, that paint is just one more layer of insulation.”
How to properly wire your marine alternator?
ALTERNATOR WIRING… How do I wire my marine alternator? Many alternators require ignition voltage to initiate charging. You must verify that all required connections are connected to the proper terminal and have the correct voltage in order for the alternator to operate properly.
What kind of alternator does Delco marine use?

What are the 2 wires on an alternator?
An alternator typically has two wires – a main connection (usually labelled B+) which delivers power to the car (and charges the battery) and an IND wire which feeds the internal exciter coils of the alternator. Without a current to the exciter coils, the alternator produces no output.
