I put a new starter on yesterday. the starter engages the flywheel but will not turn it. the battery is well charged. I drained the lower unit and had no water or metal shavings in the oil. I also took the 4 plugs out , put it in gear and was not able to turn the prop. last time I used it, a week ago, it ran fine. I heard no unusual noises. pulled up to the dock turned the motor off, got my truck trailer and loaded it up. a week later go to the water and heard the starter engage the flywheel but it wouldn't turn it.if anybody has any suggestions, I would be most grateful.

Remove the plugs, grasp the flywheel and try to turn it. If you can't turn the flywheel with the plugs removed you have either of two problems: 1) Lower unit locked up or 2) engine seized. Determine which it is by dropping the lower unit. If you still can't turn the engine, you have a seized power head or you installed the starter incorrectly and it is binding the flywheel. If you can turn it by hand (or the starter) the lower unit has an issue.

thanks silvertip, I will drop the lower unit this weekend. also, there is only about a two inch space that the gear on the starter attaches to the flywheel .I think I'll drop the lower unit first. thanks again. If I have it in neutral and try to start it, wouldn't it be out of gear. would the lower unit come into play. just thinking about it.

In normal operation that would be true.
If something broke and is jammed in the gears it could prevent the drive shaft from turning when you try to start the motor.

Re: 1997 evinrude 115hp seized

The gear shifting is done in the lower unit, not at the top near the engine. The drive shaft runs from the crankshaft on the engine down to the lower unit hears. If something is amiss in the lower unit it can prevent the drive shaft from turning and hence the engine cannot turn either. Why drop the lower unit first? All you need to do is use a screwdriver and pry the flywheel a bit using the ring gear teeth if you can't get a grip on it. If there is a cover over the flywheel, remove it for access. Do the easy stuff first.

Re: 1997 evinrude 115hp seized

this engine has two covers on top of the engine. one on top has 3 screws. the one underneath that one has 10 or 12 bolts, along with many other parts to remove. it would be much easier to remove the lower unit because it has either 6 or 8 bolts. of course I will take the prop off which is no big deal.

not only that...if it is one of the OIS 115 's, then you have all the timing adjustment parts to remove as well... if you do, mark them well...

id drop the starter and then turn the key to see if the starter spins.....it is possible it was jammed...that would be easy...


another guy here had the gear on the starter pop off....

good luck

Have you tried to rotate the flywheel with a wrench? Just pop off the timing wheel cover (3 screws) and use a wrench or socket to rotate the crankshaft. I think it's 13mm or 14mm. Rotate in a clockwise direction only.

yes, tried that, but it wouldn't turn. I'm going to take off the lower unit next. I was very careful putting the starter on, so, I know it's in the motor or lower unit. maybe the water pump came apart. It hasn't been replaced. always worked fine. I would always check to be sure it was pumping water.

You need to disconnect the shift rod which is in the powerhead usually kinda under the carbs. You shouldn't have to remove the carbs to accomplish this.

Also, get one of these 1997 Johnson Evinrude Outboard Service Manual 90 115HP 90 Degree CV 507267 | eBay (not being a jerk here. factory service manuals are awesome and worth their weight in gold)

Make sure you get the correct manual. I thought we were talking about the 60 Degree looper here.

There are seven bolts that need to be removed plus the shift rod disconnected. The four bolts on the side of the leg, the center bolt above the prop shaft, the trim tab and the counter sunk bolt underneath the trim tab.

if he has two covers on the flywheel, then he needs OMC manual # 507268

which is for 90, 105RW, 115 , 150 , 150W, and 175 60 degree Looper V's
