quote Fisherman6:

I made a self contained battery-solenoid starting box using a Li-ion motorcycle battery, a marine tilt-trim solenoid, and a starter button inside a small plastic tackle box. I had to get creative with mounting things in place and making right terminal posts but it works. With that you can remove the factory harness from under the cowl and replace with a pair of battery cables to the starter leading out the hole where the plug was. No need to hook up the choke solenoid on a tiller motor. If you wanted to add a kill button or even a lanyard safety switch that could be done too. With the start box you don’t have to carry anything more than you would with any other electric start option. The Li-ion battery only weighs a couple pounds and will start a Big Twin without hesitation. It cranks an 18 over like nothing. That may be a worthy consideration. I have a Golden Jubilee Fastwin and a 62 Johnson FD in electric start and luckily have the correct harness. If I didn’t, this is how I would get around it. My 0.02.

Thanks Ben. So you happen to have photos of your design? As they say a picture is worth a thousand words. Maybe i can replicate it in some ways.

Thanks,
Shane

I have not had a chance to get to the shop since last week. I’ll see if I can get a few pics of the start box and post them.

I have a 1960 Fastwin tiller that was converted to electric. The solenoid is mounted to the right rear of the lower cowl pan and two heavy cables come out of the lower cowl pan on the right side, near the shift lever pivot. A waterproof momentary contact switch is mounted in a new hole in the front panel, and a kill switch is in the place where your motor has the multiple connector. Manual choke. I use a jump-start unit for a battery. It’s light and portable. You don’t need a big battery. Just another approach, perhaps not as elegant as Ben’s.

I converted my Sea King 15 to electric start by mount the solenoid on the side of the motor with bracket part numbers121562 and 311218. Its a 2 piece bracket. The turned the stop button into the start button. I took out the idle screw so I could kill it with the throttle like a 5.5 or 7.5. You can remove the hardware on your motor where the old plug socket is and mount your start button there. You will have to also drill a small hole in your lower pan for your battery cables.

Here are a few pics of my battery /start box. It took me a little longer to get the pics than I hoped but here they are. The solenoid is mounted under the white plastic plate that hoods the terminal bolts. There is a switched 12V+ and a 12V+ always hot, and the (-) terminal. That gives me the option to use it to start motors that are wired to connect to a boat mounted solenoid box as well as just as a battery to start motors with on board electrical.

Need a solenoid. The starter draws a lot of current. And if you want to be able to do remote kill, you’ll need a switch with two M (magneto) terminals.

I built my own harness for my 1959, but definitely a labor of obsessive-compulsiveness:

I would have considered a modern connector, but could never find one rated for the amps.
In later years they moved the start solenoid under the hood, and the connectors got one more pin (to energize the start solenoid).

Looks like the link for my album has changed: https://goo.gl/photos/sn7pNWyUxjHJebZQ7
