1964 evinrude 60 hp shudders then jumps out of gear and revs right up, PLEASE HELP

[perron582]

can anyone please help, i finally got my 1964 60 hp evinrude sportfour running great, i had to order a water pump, installed it and it was working great i then took her out and she fired right up got up on step, then she started to give like a big shuddder then bogg down so i would push the throttleall the way then she would jump out of gear and rev up so i would pull back on the trottle and she idles fine. as soon as i put it back in gear it would do it all over again and again? please does anyone have any ideas?

Welcome to iboats.

Generally that would be caused by a worn out clutch dog or a bad gear but either way it is a lower unit problem for sure.

I would drain the lower and see what comes out, you are looking for any metal chips and note what color the oil is.

On an outboard the driveshaft comes down from the engine to a pinion gear, that gear is always in contact with the forward and reverse gear, if the engine is running the gears are turning, as you shift from forward to reverse a clutch dog in between the gears moves forward or back to engage "ears" on the inside of the gear, over time those ears wear and it causes the engine to jump out of gear like you describe.



And stop running the boat till you figure this out, everytime it jumps out of gear you are doing more damage.

no metal filings and oil was still fairly clean. i think we got that figured out now she has no power, can we remove the prop and put her back in the tub to run her and see whats goin on without water spashing every where? not sure if thats a good idea, we also noticed a small piece of metal broken off the end of this small tab under the sproket pully thats attached to the magneto, the shifting arm that runs vertical up to towards the fly wheel gets caught behind that broken piece, and the engine doesnt seem to run properly or start when it gets stuck behind that broken piece,almost looks like it should be rounded or look like an L, i cant find any pics of it or discriptions in my Seloc manual

Sounds like a neutral lockout mechanism, which keeps you from revving too high in neutral.

I don't think running it in a tub will show you much, can't put it under a load. You might check and see if the prop hub might have spun.

Well we took her out on the lake, runnin fine in neutral shifting good but only bout half throttle is all we could get out of her, then we ran out of fuel! Almost 8 gallons in fifteen minutes! Got her homepulled the carbs off bit of green gunk everywhere, the float is in bad shape u can peel stuff off of it with ur finger nail almost looks like wood! There wasn't a bloody fuel filter inside! Now gonna soak the jets cause they don't want to come out feels like they r trying to strip any advise if they do strip?

Re: 1964 evinrude 60 hp shudders then jumps out of gear and revs right up, PLEASE HEL

Fuel filter is a screen in the fuel pump. The green stuff is what is left over when the gas evaporiated because it was not drained for proper storage. The "wood" float is actually cork, probably should replace it with the foam type. You might be able to clean the jets while they are still in the carb if you have to, just use some fine copper wire and run it through the jets several times and hope you get all the junk out.

Ok will try that wire cleanin if they don't want to come out gonna try n git a couple carb kits locally tommorrow, any chance a new float will come with the carb kit?

An OEM kit should come with a new float. The Sierra kits do not.

Re: 1964 evinrude 60 hp shudders then jumps out of gear and revs right up, PLEASE HEL

well did a compression test, #1 was 84 psi #2 was 87 psi #3 was 94 psi and #4 was 85 psi, i took the heads off and #3 head was really pitted allthe cylinders looked not too bad, no scratches or pitting or gouges, not too bad for carbon build up either, i have been using sea foam in the gas tank. im not sure if there is suppose to b any play in the pistons, i couldnt move them in or out by hand but there was a tiny little bit of play up and down and side to side. before i did the compression test i warmed it up in a barrell for the first time, and there was a lot of blacksludge in the barrell when i was done. not sure what the psi should be around for this engine, anyone have any ideas?
