I noticed when it did that jerking the Shift Handle would vibrate in and out of forward....

Oh yeah - and it's pretty bad by the sound of it. I hope the gears are okay.

yikes.....it is time to turn that motor upside down for disassembly and a parts list!!!

Re: 1957 35HP Big Twin (hitting hard Knocking)

OK, sooooooo Drained the WATER from the lower unit (No Oil), then put motor upside down and removed Dog and inverted it and oiled it up. HAPPY ... WORKED GREAT!!! But there ALWAYS is a sad part... My danm trailers wheel flew right past me and I carved out the asphalt on the road for a while. Tax dollars I guess. Anyway, a nice neighbor retrieved the wheel and I barely got home...

that looks better!! you had good luck with the motor, but bad luck with the trailer!! did you replace or plan to replace any of the seals?? i would completely reseal it before its to late!!

 

[bigballerg]

Re: 1957 35HP Big Twin (hitting hard Knocking)

No, it was more for a quick check... I am going to order the seals, etc.. but after that trailer deal im done for a while... THANKS ALL for EVERYTHING!!

Re: 1957 35HP Big Twin (hitting hard Knocking)

If you're not doing the seals for a bit, keep an eye on your lower unit oil. Crack the bottom screw after every run and check for milky oil. If it's vanilla shake, drain and refill it...

Re: 1957 35HP Big Twin (hitting hard Knocking)

I did a run and the oil looks not milky (whitish) but rather yellowish...

I'd run it for about a week and then check it. One run won't tell you much unless the seals are absolutely shot.

Update... So, I eventually removed and replaced with new clutch dog, seals, etc.. Took out for a spin the other day at WOT and then died pretty instantly. Could not get back up and running BUT noticed it was steaming at the exhaust housing. I ran a barrel test the day before to make sure impeller was working and cooling engine before this incident. It turns over and idles for seconds before dying out or it just cranks, cranks and cranks with no idle. Spark plugs sparking, fully charged battery. Tried every carb adjustment etc, opened carb for clog found nothing wrong. I think it overheated and now I need to know what to check before throwing in the garbage

Remove spark plugs, inspect plugs for water traces.... Do a compression test... Drop the lower unit and double check the water pump assy... Let us know what you find.

Re: 1957 35HP Big Twin (hitting hard Knocking)

No water in plugs.. actually look like they were hot.. you know that look with a film or carbon on them?

 

[bigballerg]

Re: 1957 35HP Big Twin (hitting hard Knocking)

can I sand down the plugs to remove that film?

 

[bigballerg]

Re: 1957 35HP Big Twin (hitting hard Knocking)

Dropped lower unit yesterday to take a look at impeller and overall and seemed all ok?

 

[Chinewalker]

Re: 1957 35HP Big Twin (hitting hard Knocking)

[bigballerg]
