Super Jet It just keeps getting worse. :(

So if any of you have been following the drama, I had a no start then a no spark condition(actually it only sparked when I let off the start button) that after a lot of help from folks here I diagnosed as a bad pulser coil.

I pulled the flywheel cover and the inside of it was covered with premix and metal shavings. Pulled the flywheel a minute ago and it is far worse than I would have guessed. The stator was not even connected to the engine, it came out with the flywheel. I found one full stator screw and one half of one. So, yeah, I've got a broken screw in the engine. Oh and the flywheel magnet is toast as well. Most of the chunks of metal come from the stator, as you can tell by the missing pieces on the stator plate. The good news is my diagnosis was right since the red white wire was snapped off the pulser coil.

Could all of this goo possibly come from just a leaky crank seal?? Oh, and when the time comes, how do I know the correct placement of the stator since I don't know where the original was since it was flopping in the breeze?

There is a timing mark at 8:00 if you are looking at the front of the motor. You align the arrows up.

Thanks BK. So, do you think this was a crank seal issue (all the premix muck) ?

 

[Big Kahuna]

Cannot say the crank seal caused that. I have had that happen with the stator. It may have gotten loose then the tabs break out where it mounts to the case (outer part of the plate). When this happened, your RPM's start varying due to the timing advancing and retarding. I got lucky and caught mine when this happened. Then it lets go and pieces go everywhere. But looks like you need to at least replace your crank seals. I would inspect the crank while your at it.

My real question, I guess, is "is there any other way I could have ended up with premix/grease/oil in this area besides a bad crank seal?" The seal is intact, but there is so much crap I can't tell much beyond that...at least not while the engine is still in the hull.

There is normally a fair amount of brown grease in there that is from the bendix when it is greased from the factory. It gets slung around from bendix engagement. It looks like you may have more oil/grease there than normal, but it is difficult to tell because of the gray metal as to what color it is.

Safe bet is to pull the motor and do crank seals. It can be done by removing the bottom case and pulling crank upwards, but I would just split the motor down if you are going to do it. Much easier to extract the broken stator bolt on the bench anyways.

PM me if you need gaskets, seals, flywheel, stator, etc and I will give you a price.

Best of luck!

That could be simply water that has gotten in there. I have popped my cover and found the same thing.........

The grease/oil/sludge is grey, and it smells of gasoline. maybe the premix leaking from the crank seal mixed with the bendix grease, and this is the result. I also found a 'standoff' in my engine bay after the flywheel popped off, but it was clean. It's like the standoffs that slide in the bolt holes of the coupler cover. No freakin clue where it came from, but I know for sure it wasn't there before I popped the flywheel. Maybe it was under the motor all the time and the inertia from the flywheel popping made it roll out from under the engine.

I feel like throwing up. I do have a stator on the way from Jetmaniac, but I'd love a price on a flywheel (stock or lightened).

Friends boat had a similar stator failure last year, same grey look, some oil, we wiped it clean and replaced the broken parts and cleaned out the bendix been fine since.... Pan head failed on one stator mounting bolt on his.

The oil under your cover did not cause this machanicel failure, I often find oily residue under flywheel covers

#zero on this site has stock lightened wheels pretty cheap

That stand off May have come from your Electrical harness currently or in the past. One of my battery cables has black plastic bolt mounts zip tied to it for mounting to the flywheel cover and standoffs go in those so the flywheel cover bolts don't crush them... It may have been an old part to, I've lost many a items dropping into hull never to be seen again until some future repair work

That sounds exactly like what happened to mine. I just pray I can get the busted screw out. Did your buddy replace his crank seals? Also, I bet you are correct on where that standoff came from. Thanks!

Holy carnage under the fly cover! That is a mess for sure. You need to clean everything and then inspect cases for damage as well. You may need to manually center the stator on the crank if mounting bosses on the cases are badly worn.

Definately need to clean and inspect your bendix as well.

 

[SXIPro]

Maybe I'll do a leakdown test before I go any further, but I suspect with the smell of gas within the goop all over the place, it'll point to leaky seals.

I am not sure what you mean by manually center the stator...etc etc. As far as mounting bosses, you mean the ones where the two phillips head screws used to reside (and half of one of them still does)?

Yes, there are 4 locating bosses on the cases. 2 have the screws to mount the stator and 2 just to support and align the stator plate. Many times when stators come loose and move around, the stator will wear the bosses down and stator will not automatically be centered any longer.

Gotcha! Thanks. Oh and could you PM me prices on flywheel (stock or lightened), crank seals, and 1211 please. Looks like I'll be receiving the stator today. Thanks for the quick shipping.

On the screw extraction, as long as it wasn't cross threaded they usually come out pretty easy once the head breaks off releasing the torque on the threads. I usually start with a left hand bit if I can't grab it with pliers and once it catches, often it will back out the broken screw.

We didn't replace the seals as it was a start of season failure. I also had the flywheel off in the recent past so I had already wiped it out so it did have years of build up. Only oil no fuel smell in their though....
