Happy New Year.

The ’83, standard rig, C-25 which I purchased last summer came with an ’83 Evinrude 9.9 HP, 2-stroke, outboard motor. It starts beautifully and runs very well. But, it had an electric starter that did not work and a battery charger (I think). I took the motor off my boat last weekend and took it apart (well, not completely, but enough). I found that the starter switch was shot, but that the starter motor works (I tied it to a tree and jumped it from a car battery). When the engine was on the boat and running, I measured about 13.5 volts from the two heavy wires that were attached to the engine but were not hooked up to anything on the boat. That is why I think that the motor has battery-charging potential.

I plan to replace and relocate the starter switch to somewhere on the boat near the stern. I will run the hot wire to the momentary switch and then directly to the positive battery terminal. The other wire is grounded somewhere on the engine so I will connect it directly to the negative terminal of the battery.

My question has to do with the wire that must come from the alternator (magneto) which was connected to the positive battery side of the starter switch. I think that I could just splice a fairly small (compared to the wire in the starter circuit) wire from there to the battery side of my new starter switch, but I’m not sure. Would it make more sense to run that wire to the battery switch (the big red “1, 2, both” switch)? I’m pretty sure that there is a diode in that charging circuit, part of the rectifier, which would prevent the battery from running down when the engine is not running, but . . . Or does it make any sense at all to be charging a battery for the few minutes I use the outboard to get out to the lake and back to the dock?

Thanks,
Dan

My motor says make sure the cables are hooked up to the battery
while its runing , or it will burn out the regulator.

And 13.5 sounds like its chargeing

Sean,

Thanks for the insight - but I will have to check that voltage again - I have used the motor quite a bit without being hooked up to anything. And I still have to find a starter switch . . . Then I can find out if I have fried the regulator. If I have, that answers the question of the value of charging my battery using the outboard.

Thanks,

For most people a kicker does not run long enough to contribute to the state of our batteries. Mine certainly does not on the way out of the marina, occasionally I will motor to the marina if the wind has died on me, but usually I sail to the marina and only motor in to the slip; that is 3-5 minutes each way. I think the charging function is only viable for fishermen who run the engines long periods.

The only time I get any charging benefit from my Evinrude 9.9 is when I'm motoring out to Lake Superior, 45 minutes to two hours. Beyond that I rely on a solar charger.

P.S. that is not to say you should not have all your systems 5X just on principle. Mine is hooked up even though is serves no purpose.

I think the caution about the regulator is <u>don't disconnect it while the engine is running</u>. I don't think it will hurt to run it without a battery as long as you start it without a battery.
