Motor Frozen?

[sirdick]

I tried starting my 1968 Evinrude, but all I get is a grinding noise like the starter is trying but the flywheel doesn't move. Anyone know if the motor is frozen? <br /><br />Thanks for any and all help <br /><br />Sir****

Re: Motor Frozen?

If the starter drive is popping up and engaging the flywheel, but it doesn't turn something ain't right. Try pulling the spark plugs and see if you can move the flywheel by hand. Has the motor been stored a while?

Re: Motor Frozen?

I just came back from checking on it. The starter drive does not move. Just clicks at the solenoid. More than likely a bad solenoid. I am guessing that it hasn't run in almost 10 years.

the pinion gear that engages the flywheel. spray it with wd-40 real good to begin with. Then after it soaks for a few minutes. Pry it up with a flathead screw driver(it will come up with a slight twisting motion) Once you get it up there clean the shaft it rides on with wd-40 and a rag REAL GOOD! as clean as you can get it.work it up and down and clean again. once it is completly clean. oil it with a little strait 30 weight motor oil, not to much just enough it coats everything real well and it it worked behind the pinion gear. That should take care of it, this needs to be done from time to time. Make sure you have a strong battery. Then if the pinion engages the flywheel and the motor doesnt turn over. You have other problems.<br /><br />Suzuki40

Re: Motor Frozen?

if its been sitting for 10yrs it wouldnt hurt to spray some deep creep around in the cylinders while the spark plugs are out, let it soak in there. when a motor sits for that long the rings tend to stick. then when you get it started the rings will break, then you will have "big" problems. <br />thats what i would do anyways!

Re: Motor Frozen?

I want to thank all for your help. I tried everything that everyone has said and unfortunately - nothing still. The solenoid just clicks even with a fully charged battery. The flywheel still will not turn. The starter drive is freed up and turning freely though. Looks like I will have to start taking the motor apart and disect. What does everyone think. All advice appreciated.<br /><br />sir****

Re: Motor Frozen?

sir - Don't start rippin parts off just yet.<br /><br />Tilt the motor up or put it on the floor with the spark plug holes up. Get some Marvel Mystery oil and squirt liberally into all cylinders (you didn't tell us which motor you have). Let it sit for a day or two (afer all it sat for ten yrs & can wait another two days). Then take a breaker bar & socket & put on the flywheel nut on top. Have at it - - - give it a good rap if you have to. If that dosen't do it you will need to pull the head & see what you got. Sometimes even then they can be freed up by putting a block of wood on top of a piston and giving it a walop.

Re: Motor Frozen?

Sir ,<br />Are you saying that the flywheel will not turn at all, even by hand or with the starter rope?? You didn't mention a model number here , so we're guessing as to the HP.<br /><br />Or, are you saying that the starter drive will not engage the flywheel when you close the solenoid??<br /><br /> Or both.....

Re: Motor Frozen?

Will give it a try tomorrow. The motor is a 1968 Evinrude 85 H.P.<br /><br />Thanks

Re: Motor Frozen?

Sir, While you're at it....remove the 2 large gauge wires from either side of the solenoid and clean up the connections. Be sure that the starter is bolted to the power head and making a good ground connection as well. Corroded connections can be a source of high resistance which will limit the amount of current to pass to the starter itself. A high amperage device like a starter needs good connections to work properly. You can test the solenoid by jumping the 2 large cable connections on either side of the solenoid (beware of possible sparks). If the starter fails to spin, there can be 3 causes, a bad starter connection from the solenoid, a defective starter, a bad ground of the starter itself to the power head.

Re: Motor Frozen?

I have already changed out all of the wires on the entire engine and cleaned them as I went. Most of them were dry rotted and need to be replaced, so I changed them all. The flywheel will not turn either by hand or trying to pry loose, and the solenoid just clicks and does not send power to the starter. Thanks again. All help appreciated.

Re: Motor Frozen?

IF you cannot turn the flywheel by hand...you either have a siezed up engine...or a siezed up gearcase.<br /><br />TMD

Re: Motor Frozen?

I'm hoping not, but that is the way it is looking. The boat and motor has been seating a long time in Chicago in the open weather without being covered. I will try all of the other suggestions first and go from there.

Re: Motor Frozen?

Easiest way to find out what the problem is...remove the gearcase assy..then see if the crank turns or the driveshaft turns.<br /><br />TMD

Re: Motor Frozen?

Hey sir****, a while back I asked about things I should do before starting my 115 Johnson that had sat for 4 years. I was told to not even turn it over before replacing the impeller. I guess if they're old, they can break and clog up the cooling system. So, maybe you should do that first, and perhaps find the problem while you're in there.

Re: Motor Frozen?

v4 evinrude starflight electric shift, dont give up yet! try what the marine doctor said, take the lower unit off so you can isolate the problem, if the shaft on the lower unit turns freely the problem is in the powerhead. you said that the solonoid clicks but wont send power to the starter, try taking the plugs out and put jumper cables directly to the starter (not the solonoid), let the starter kick it a few good times, just try to get the pistons to move a little so you can work them free. keep spraying deep creep all round into the cylinders i think you can get it freed up! good luck

Re: Motor Frozen?

if the flywheel is not even turning by hand dont try to engage the starter because you will burn it up. pull the plugs and soak the cylinders with pb blaster for a few days each day add more pb blaster and work the flywheel back and forth by hand you might want to try a strap wrench to get it to turn.dont go crazy because you can break the rings just use even steady pressure and try it over a few day span. dont be cheap with the pb blaster really soak the cylinders good and leave the plugs out. dont worry about the water impeller untill you get the engine unfroze. good luck i have dont this to 4 engines and it has worked for 3 of them the other 1 was wat to far gone.

Re: Motor Frozen?

Engine unfrozen - New problem. No power to the starter. I have power to the solenoid - but there is no power from the solenoid to the starter. I show 12 volts from battery to the solenoid. No power coming out of the solenoid to the starter. Is this a sign to buy a new solenoid, or is there a test that I can do? I have cleaned all connections and made sure that they are tight. Any help would be appreciated.

Sir see Catfishes reply above on jumpstarting starter. good luck with the engine. even125

Re: Motor Frozen?

Sir****,<br /><br />Try this, disconnect the large battery cable leading from the solenoid to the starter, from the solenoid. Place your volt meter at that large stud and turn the ign. key to the start position. If you read 12VDC then the solenoid appears OK . Since you would have a reading with the cable disconnected , this would point to the starter itself being internally shorted to ground. If you don't get 12VDC at the solenoid after disconnecting the starter cable side of the solenoid, the solenoid needs replacing.
