1967 Chrysler 45hp

[The Brad]

Hi All. Its been a real pleasure trawling this forum and I have gleaned many pearls of wisdom from this fantastic forum of late. Really super stuff.
I recently acquired a 67 chrysler 45hp to power my 16ft Volero 16 footer. (not a Larson Volero, its made by the Australian Volero Boat Co and is a halfcabin). I've seen the motor run, change gears etc but now that its time to connect to my tub, the wiring has me rattled. I have attached a pic to help explain my problem. The starte solenoid post that connects to the starter motor also has a red wire going to the silver unit? I also need to wire a new key start. Loking at the block connector panel, I really dont know what does what. I only know that the 2 black lamp wires are the magneto cut offs and I suspect that the rest of the solenoid arragement is wired incorrectly. I have a wiring loom with over-heat alarm but not sure if the motor has a sender unit for it. I'm pretty clueless all round arent I?
A penny for your thoughts.
Many many thanks for all help past and present.
Brad

Can't really tell you much.I can tell you the 45 may have a magneto ignition or a battery ignition with a flywheel alternator generator.
You really need a manual To determine what you have.There is also an involved timing prodedure,flywheel removal and install.You may find a manual at the library.

Many thanks and you are right. A manual will be a good start.

Cheers,

Re: 1967 Chrysler 45hp

Did you find all or most on the info on the 45hp? I have a 1970 Chrysler 35hp and I'm willing to share info from it. I had a good service manual in 1985 that had very good details for all services. The manual got away with friends!! Since I have serviced yearly from memory and a CD that is not good compared to the specific manual.

I have read that the Chrysler 35hp-55hp is the same blocks and etc for a number of years. If I can help I'll send pics to ID my motor and certain procedures. OR! Search Wickware and JOW (separately) and you might find some tips and attachments on various procedures.

Good Luck!

The starter motor red wire is on the wrong post of the starter solenoid. The battery red should attach there and battery black should attach to a good engine block ground.

( Note that there is really no right or wrong--It is just easier to attach the battery red to the front terminal. IF you use the rear terminal, then the red from the circuit breaker must also go on that terminal.)

The silver can is the circuit breaker and is wired correctly. One red wire should go from it to the battery side (Front) of the starter solenoid. I could not adequately see, but a yellow wire should come from the brown switch on the other side of the engine to one of the top small terminals on the starter solenoid. A black ground should attach to the other small top terminal. The brown switch is the neutral interlock and prevents energising the solenoid with the engine in gear. The white button must be depressed to allow current to flow to the solenoid.

NOW: You need a multi-colored cable (red, blue, white, orange, purple, yellow, green, and black) to go from the engine to the starter switch. At the engine just connect color to color.

At the switch, connect red to the battery terminal, yellow to the start terminal, and green to the choke terminal. And now, here's where it gets tricky because magneto ignition is wired differently than battery, coil, and points ignition.

The black "lamp cord" is usually the magneto stop circuit and shorts both sets of points together to stop the engine. If this is your ignition type, then white and blue in the cable each connect to an "M" terminal on the ignition switch. If this is your ignition, there is no alternator and you will need to recharge the battery periodically, depending upon use. Note that magneto ignition is self energising; the battery is only used to start the engine and power accessories. Thus, the engine can also be pull started by hand with a rope around the flywheel.

Orange is overheat indicator and there should be a 5/8 headed bolt with a terminal on top located on the head. This is the overheat switch. At the dashboard, one wire of the overheat indicator attaches to the "I" terminal (only has 12 volts when the switch is on). The other wire connects to the orange. When the engine gets hot, the thermoswitch on the head closes to ground and voltage flows through the indicator (buzzer or light).

While the 45 is a nice engine, your 16 footer will be a bit underpowered with it. Don't expect more than about 20-22 MPH with it unless it is a very light "tinny."

Note that that is a 50 on a 10 foot tunnel hull in my avatar. It can touch 44 on a good day.

Re: 1967 Chrysler 45hp

Thanks Frank! This helps all of us with our "Early Model Chryslers". I have a 70 35hp Chrysler with the magneto and points ignition vs battery, coil, and points ignition. Pull starting is no problem if I drain my battery with lights, etc. while fishing. I have 2 questions I would appreciate you help with:

1. Is there a seal or bushing to prevent crankcase blowby from the points?
2. Is there a set temp to test the overheat thermoswitch in hot water?

Thanks,
JOW

Re: 1967 Chrysler 45hp

The points carrier stationary plate is bolted to the block with four flat head screws. This plate also contains a bronze bushing to locate the plate the points are screwed to and an oil seal. If you are getting blow-by, you must remove the four screws that hold the points carrier down to the ring, then remove the plate. Now remove the four flat head screws holding the stationary plate and press out the seal. The seal is a standard one and can be purchased at any bearing supply store.

I never tested an overheat switch. I don't think I have ever had a defective one. It is a dirt simple bi-metallic thermoswitch. I suppose it should close at boiling water temp since the thermostat is usually around 160 degrees.

Re: 1967 Chrysler 45hp

Thanks Frank!

I?m sure you remember telling me this bushing/seal and over lubing point?s cam lobe info before. I have a better feel for your instructions "Saved" (if I need them). I did not have a chance to run the engine in the Hot TX Summer Heat Again (to see if it was just an over lubing matter). Since it was my first summer since 1985 to notice signs of vapor. I hope you keep all of this helpful info saved on your computer, But! it sounds personal to me.

Thanks! From All,
JOW
