Johnson convert to electric start

8 posts in this topic

I have a 78 Johnson 35hp motor I am converting to electric start. I have the bracket, starter motor and solenoid installed (tested off the motor and it works fine). The next step is to wire the thing up.

My question is this: If the motor is in gear, there is a plastic arm that moves that prevents the recoil from being pulled, so that the motor cannot be pull started while in gear. Is there also an electric circuit I should be tapping into that would prevent the starter motor from starting if the motor is in gear? It would be nice to have this so I couldn't accidentally start the motor while in gear.

console or tiller?? if its a console there might be a switch in the controlls...it wouldnt be to hard to do you could just wire that switch between the key and the starter.. so when its in netural the silnoid will get power and when in gear it wont.. it doesnt really hurt anything to start the motor in gear.. just is really un safe if the throttle is advanced past idle..

Usually there's a neutral switch near the slide for the shift linkage or it's in the control box. If you didn't have an electric motor to start with there likely isn't one on your motor to start with.

I forgot to mention this is a tiller motor. I don't know if it's built into the controls (the reverse/neutral/forward switch) or not. I think there are a couple wires that are nearby that switch so I'll try probing those. What I'm looking for is if there is a wire that is ground only when the switch in is neutral.

If it's not possible, I'm not going to worry about it too much. Just gotta make sure the motor is in neutral when I start it so I don't get thrown out the back of the boat! smile Someone with a factory installed electric start Johnson/Rude from the late 70's-early 80's might be able to tell me if they can start their motor while it's in gear and that would probably answer if it's possible or not.

just make sure its always started at neutral or ata an idle.. you should be fine.. neither of my 2 tiller jhonsons have any sort of neutral lock out..

Thanks, that's what I was thinking, but I wasn't sure.

Since there's no generator/alternator on this motor, it won't be charging while I drive around. What kind of battery should I use and about how many starts can I expect per charge?

just about any larger sized car battery will work.. if you use a trolling motor look into a marine deep cycle made for cranking and slow draw.. ohh i would imagine 30 to 40 considering it starts easily.. but it should never go dead if you charge it, you have the pull starter yet right?

Nice, 30-40 starts should be plenty for most trips. The first start of the day usually takes about a half dozen pulls or so, but once it gets going it starts pretty easy. Yeah, I still have the rope to fall back on, but it will sure be nice not to have to use it.

    • Just use plain old spray paint in a can. I've done it many many times and seems to stick really nice. Nothing special either I can't even tell you the brand because I have no clue. But as mentioned doing 2-3 light coats helps.
    • no expert here, but heat doesn't rise. heat radiates in the direction of least resistance (R value). warm air or water rises because it is less dense than colder air or water.  If you don't insulate you will be heating the ground under your cabin and the earth is a very large heat sink $$$. get some info from an expert in the radiant field as far as tube diameter, spacing, water temp, manifolds, length of runs, and so on. it varies on amount of windows (solar) ceiling height and room type (bed, bath, living area,  storage etc.). once you pour over the tubing you get to live with it. I did my own Home 15 years ago and got some good advise (wish I would have taken it all)
    • Sonar works from above, cameras need to be submerged. What am I missing here?
    • I've also had good luck spray painting PVC.  Biggest thing I found is to do lots of light coats, the PVC makes the paint want to run in a hurry.
    • I believe you can do this with the Lowrance HDS 9 and above.
    • I'll go with another loss in overtime.
    • Calling a win tonight, it's going to happen!
    •   You'll probably run into plenty of "experts" among the experts, too...   Floor heat is nice, but definitely not the best option if you're looking for the best efficiency, since it is a slow recovery system.  If you were looking for efficiency and lowest cost, I would suggest looking into a mini-split heat pump to complement the gas furnace if you have off-peak available.   (Disclaimer: Not an expert either, but I have stayed at a Holiday Inn Express a few times.)      
    •   Same here. I have 3 of them. Use them in the SUV, Boat, Snowmobile, and Dual Sport bike. They seem to work better on my sled in the winter with no issues at all over my old ifinder which would eat batteries in the cold. They are discontinued but you can still find them out there on the List or bay once in a while. I like them as they are a crossover and can be used on the road or with a lake map which is the main thing I use them for. Wish they would bring something like it back.
    • Ridiculous... but it would work.  Sorry to offend, guess I don't get quite so fired up about concrete.
