SO: If the boss of the house (CFO-Chief Financial Officer) will not release any more money, first check with the plugs out to see if there is spark, then try to pull or rope start it. Once you prove it to run, then she who has that thing you can't live without (I mean the purse strings) will release more money.

Ok now we are in trouble, Frank has got his shirt off :D, and if you can't get it to start, try a teaspoon of fuel in each cylinder, you may also have blocked carbies from the motor sitting so long. But there is always a way to corrupt a CFO, shoes for example :p

My wife derisively calls them Man T++s, trying to get a rise out of me, but I reply that they are Silverback gorilla pectorals.

When I first got my '98 90 HP Force it acted like the batt was weak. After checking all connections and sure batt was good I removed the starter and disassembled it. Everything looked good so greased the shaft bushings and apparently they were the problem. It still cranks good after 5 yrs.

Seems like no fire now. Comp test was 120 on all 4. I'd there a kill switch? Got boat with no key or ignition, been jumping from under the starter.

Re: new used boat owner

Well that is your problem, you need power to be on the blue wire which it gets from the ignition switch, So you turn your ignition to on and it supplies power to blue, you turn your ignition to start and it supplies power to yellow. You can manually operate the choke, make sure you choke it on the first start, I only choke once. You could rig up a two switch system to start your motor, just two normal house switches will do, I use a house switch and a momentary on switch. I rig up one switch with the red in the common and blue and a tail in the switched side of the switch, the tail runs off to the other switch as the common and the yellow and green on the switched side of the second switch. you turn the first switch on that will supply power to blue, you then turn on the second switch which will start it and pull in the choke a momentary on switch will turn of power to the starter when deactivated. I will post the actual wiring diagram and if you have any questions just ask. You will need to make sure that the neutral switch is activated otherwise you won't start it.

Re: new used boat owner

can't quite tell from you posts what you have in the way of a wire harness. You might have no harness at all, or everything but the key switch. But the compression is good, so I think you can make a pretty strong case at the board meeting. :) For a full harness, I would look for salvage from a similar rig. For a starter switch, you can do the same or get a new one, depending on budget considerations. I'm not sure how you are actually connecting to the starter, but that may explain some of the starter issues. If you don't have a wiring harness, you can't safely improvise on that motor (what is it? Magnapower III?) Chances are, you may have already blown the rectifier so the charging system is not going to work without repair. SO, I think you need to get a wire harness in place as a first step. Maybe another lister has some advice on how to do that, or maybe put something together. I have done it for simple magneto systems, with no charging systems ('50s OMCs), but that is different from what you have.

EDIT: guess MickLovin, above, is trying to improvise a harness. I'll leave that for you guys to work on.

MikeB: You really need to put your approximate location in your signature box. There just might be someone close to you who can help.

Re: new used boat owner

I was under the understanding he had no ignition switch, so I was advising how I did it with a harness to my 75hp when I had it on a stand, for starting purposes only as I had my ignition switch on the boat which had the 100hp on it. It was a suggestion to see if he could get spark not a final solution, which would obviously be a ignition switch and/or harness if he doesn't have the harness. But he won't get spark by jumping the starter as it won't give power to the blue wire. wiring_Chrysler_4cyl_Motorola.jpg

Re: new used boat owner

1977 120Hp Chrysler, suppose you have the Motorola Magnapower I ign.system with distributor and beltdriven from flywheel.
This ign. system needs power 12VDC form battery (through keyswitch) for working. No spark.......you need to jump bluewire at terminalblock to red for power to the CD box if do not have a keyswitch (wiringharness). Also check so the dist. is well grounded to engineblock. The grease in the dist.swivelbushing isolate from ground.

Edit: Sorry did not see Frank, Micklovin and oldboat1 answer, but they are as me on the same trace. Needing power to the CD box because of no factoryharness/keyswitch.
No 12VDC to CD box.....no spark at plugs.

Re: new used boat owner

Thanks everyone. Should have made it more clear. There's ignition switch and no wiring harness going from boat to front that I can see. The remote has an open hole in dead center which I assume is for starter switch? There's wires under dash for tach and horn and few more, but didn't notice any coming from motor. High today of 30, after 80 degrees yesterday so won't spend much time out there today and going back to work for two weeks in morn so I'll leave everyone alone till days off. I'll look for harness later and maybe bug y'all lil more today. Dumb question, what is the cd? Again thanks everyone for your time and patience. Ps. I'm in west tx, san Angelo area. Mike. Just Saw the diagram for the wiring. That makes it look a lot simpler and has convinced me to brave the cold and give it a look. Thanks guys. Last one. .. my wiring harness has blue, green, white and red.

Re: new used boat owner

Mike -- If you have an outboard shop or marina in your area, the old fashioned kind with parts all over the place, it would be good to try and find a wire harness -- everything from the motor to the control box (and including the control box if you don't have one). The object would be to check out availability and prices, maybe for future reference. You should be armed with the model number (plate at the rear of the motor, on the lower cowling under the hood). Find a harness for your motor. If it's too expensive, be able to recognize it and keep looking for another one -- look for salvage, maybe somebody who is trying to get rid of some marine stuff. Got to make a game of it!

Re: new used boat owner

I agree with olboat1 you definitely need the controls and wire harness, but you can rig your own starting cabling as I suggested previous with the switch set up, all you need to connect to is the red, blue, yellow and green for choke. Because if the CFO finds out your spending money, I wouldn't want to be you :D But seriously if you can get the controls and harness buy it they are on ebay and maybe gumtree in your area?

Re: new used boat owner

Your wiring harness should have red = + battery/ignition 12v, black = ground, white = tacho, purple = generator which isn't connected at switch, green = choke, orange = warning buzzer negative - from the motor with the positive + coming from your ignition switch on with the blue going to your + of your buzzer, Yellow = ignition switch start, blue = ignition switch run
PICT0003.jpg
You could also use a cable which has numbering the each core, electricians call it a control cable, it comes with numbering on each core so you correspond each end, in Australia I would be asking for a 7 core and earth 2.5mm circular control cable (not sure what your cable gauge system is in America), and use the earth (Green/yellow in Australia)as your black or ground and number the rest against this picture. but you should be able to get the controls with a harness, and that hole in the remote is if you want to mount your switch there but it has to be a short base switch, mine is mounted on the dash and it is a long barrell switch so won't fit in remote. Good Luck with starting the motor, these old girls go forever if you look after them, well not forever :p

Re: new used boat owner

I messed around with the house switches for a few mins but is really cold here and wasn't exactly sure how to hook it up. My wiring harness only has four wires, but I'm sure that previous owner (s) did that. Looked around in town lil bit tonight for harness and ignition, but didn't get to boat store before they closed. Lowe's has ignition switch with 3 and 5 hookup but not sure would work or what to hook up where. Gonna try to get to town earlier. Would like to get fired up before head to work. At least know it's firing. Wanna try the house switch but not fan of getting shocked if mess it up.lol. thank you so much for all your help

Re: new used boat owner

easy way with one switch is to have the blue red together on one side and yellow and green on other, but this will keep the choke in every time you start so you need to have another for the choke or just cut it when it starts, or dont use the choke and I dont recommend this but use starter fluid just to see if it starts, don't use it normally it will lean the mixture out and cause possible damage.
if you can follow the wiring diagram you will be ok

Re: new used boat owner

The switch Chrysler supply has three functions, it gives momentary power to the choke via pushing it in until release, when first turned it gives power to ignition system = blue, then a spring loaded contact for the yellow, Red is the switches 12 volt + supply which comes from the battery side of the starter solenoid. white is Tacho disregard connecting anything to white but your tacho's signal.
So when I used 2 switches, I had one for blue and red, then a tail connected with the blue to the common of the other switch and the yellow and green connected together to the switch side of that switch. You have to turn the yellow/green switch off after getting it running and you could also use a 3rd switch for the choke so you can turn it off. this is a easy way without the harness or switch, but the switch and harness would be preferential

Re: new used boat owner

Got a battery, did the switch thing. Got motor to crank over and run for few seconds. The starter sticks sometimes but not all the time. Next step is finding wiring harness. The boss approved it so all is good. Will be water ready before I go to work in two weeks if all goes right.Thanks for all the help

Re: new used boat owner

Runs for few seconds. Got key switch and starts, choke won't engage using switch. Think it's got something to do with not being on lake since 02. Sure carbs need adjusted. Lil help how to do that?

Re: new used boat owner

Mike chexk the carbie sync and timing post at the beginning of the forum, frank explains how to do it and he has a video on you tube, I am happy you got it going, the choke may need a bit of lubrication or slight adjustment to get the plunger movement. Frank's carbie and timing post/video should get you under-way. If it hasn't been run for a while it may pay to clean the carbies out, Also have you checked your impeller and fuel pump diaphragm, be aware if you check your pump diaphragm you will need a new gasket/s so you may as well get a diaphragm as well if you proceed. Sounds good you had it going, good luck with the rest.
