Re: Evinrude 135 (1975)

Your battery voltage should not go below 10 volts  or so while the starter is engaged. If you can borrow a clip-on DC ammeter, the draw after the initial surge of 200+ amps should be about 150-175 amps.

I’ll pick one up tomorrow and give it a try, I do have a new starter on the way, hopefully it will be here first of the week.

Re: Evinrude 135 (1975)

Picked up the clip on DC, where should I clamp it to test? Starter should be in on Sat...so hoping to do some work on it this weekend.

Positive cable at battery and again at starter cable post to see if there is any differrence.

Have voltmeter on battery posts also to make sure it doesn't drop below 10 V

Re: Evinrude 135 (1975)

Installed new starter (old one was frozen up when I first got it), put a new battery on it, same thing...voltage dropped way below 10 V. Scratching my head at this point...it still doesn’t want to turn many RPM’s. I even hooked my vehicle up to the boat battery, and same results, volts dropped.
I do consider myself somewhat handy, not afraid to get my hands dirty...would just like to try to get this firing. For what it’s worth, I can rotate the fly wheel “freely”, meaning I can turn it with my hands, it is not super easy, but I can feel the compression in the cylinders...if that makes sense...much easier with plugs removed

I know my plans at the moment (once I can get it fired off), will be to replace the fuel filter, rebuild the carbs, transfer it over to my 𝑶𝒓𝒊𝒈𝒊𝒏𝒂𝒍 Boat.

Re: Evinrude 135 (1975)

Would the stator or trigger cause it to “drag” and loose voltage?

Was the low voltage at the starter or the battery posts?

 

Is the flywheel able to turn without too much effort by hand with the spark plugs removed?

Both...

 

The flywheel is able to be spun by hand (with some effort), easier with the plugs removed. Compression can be felt....

Unless there is a short somewhere after the solenoid and the starter is new, then the low voltage is due to a weak or bad battery

 

Does it crank over rapidly with the plugs removed

Re: Evinrude 135 (1975)

I'll try to go out and get a video in a few minutes...with and without the plugs. I will try to get as much in the video as possible...what all would be beneficial to see in a video?

 

Please be very specific.  I have the following "stuff"

 

1. Digital Volt meter

2. Clamp on volt meter

3. Spark plug tester

4. Circuit tester
