BRP advertising claims that the Etec puts out 50 amps beyond the requirements of the engine's operation. I have never seen information on at what rpms the engine achieves this output. I have twin 300s on my new boat and wonder how much juice will actually be available from the two engines and two deep-cycle 100 amp hour batteries net of the inverter. Can anyone help me here?

From the service manual...

I am more confused than ever. According to the Evinrude website, the following are the specs on the G2 300:

Alternator Output

133 Amps Total | 50 net Dedicated | 14 amps@ idle


Can someone explain exactly what this means? 50 net dedicated to what? 133 Amps Total at over 1500 rpm (per PropNut's post)?. 14 amps at idle but how many are used by the engine itself? Why is there a difference between the service manual and the website?

The 50 Amps is the current  dedicated to external entities to the engine, such as charging the battery, and all other external load. The 83 amps is used by the engine itself.

If you're going to ask "why do they even bother stating the 133 or 83 number?", I have no idea.

Total output 133 amps

Max dedicated charging system 50 amps GROSS, its only 10 amps at idle

The charging system is not 100% efficient

Actual charging output to battery NET is what is on the chart.
