Hey everyone, problem..... Struck a patch of sand coming into the beach, motor stalled. Get home and go to flush the motor and there isn't anything coming from the telltale!! Motor is a Johnson 30hp 2001 model. I've read previous comments people have made and have checked that the telltale outlet hose is not blocked. Need further advice please.
Cheers

Flushed with a drum of water. Ran for about 30 seconds, until I noticed no water.

I can physically blow back through the telltale and get bubbles coming out of the water. Start it up and it still hasn't got anything coming out of the telltale!! Please help.

Is your motor gauge reading hot when flushing?If not I would run a bit longer then water may come out,as mine takes a bit of time.

Ran it for about a minute. No bad sounds, but still no water. Only thing coming out the telltale is fummy smelling steam!! By steam I me it not solid nor liquid, but is not really hot. Easily hold your hand over it. All this talk about dropping the leg.....how hard is this, and what do you do?

What sort of motor? I did the same thing with my yam 4stroke (sand and all). Reverse flushed it with the flushing adaptor, then stuck it in the bucket. Did both a few times now its all good. Also gave it a kick over a few times when the hose was hooked up the the flushing adaptor and that kicked out more sand. Heaps of flow now. My OB is nearly due for a service so the impellor will get replaced soon.

Is water spitting out the exhaust? It usually will do so if the impellor is pumping water through the water jacket on the powerhead. Does the powerhead get hotter than usual if you feel it? If you have a compressor and gun attachment, try blowing up the telltale with it. Could need a new impellor though.
Cheers.

get a long piece of say 60lb line, while the motor is running feed the line from up the top of tell tail and down as far as it goes, if this makes sense

I'd say you have a very good chance of a belly full of sand. ( well derr) ....if you have no water and hot air comming out of the tell tale I would be very cautious.
Do you have water flow out of the leg in the normal places?
If not, you realy neeed to get the sand out before you go any further.
It sounds very much like you have a blockage early in the system.
You can try your devious back flushing best, but I'de be thinking about a look in side.
If you havn't baught the genuine paper manual for this outboard, now would be a good time... you will bless the day you did.
If you are mechaniclay handy ( can change a clutch in a car) you should have no problem pulling the bottom off you leg..... particularly with the manual in hand.....it should also tell you what gasgets to replace and stuff.
cheers

It is much simpler than changing a clutch. It's quite a simple job providing when it was last serviced the bolt threads were greased.
While you have it apart change the impeller.

Well there is one thing for sure...... there are less bolts to undo and you don't need to spend half a day squirming arround on you back.
I recon you would come away with less skin off you knuckles too.
After all it is just like a big lawn mower with a rightangle drive on the bottom.;D

Before you do anything, trace the telltale hose back to the powerhead, take the hose off the hose tail and then remove the hose tail from the powerhead. Chances are there is some grit or something right under that hosetail stopping flows.

Thanks for the advice everyone. I'll start as mentioned above and remove and check the hosetail, then move onto the 60lb leader. If I drop the leg, do I automatically have to replace the gasket?

2001 Johno,
I am betting the shift shaft will give you some issues!!!!
No Gasket required to remove and replace the gearbox.. seeing you have asked this makes me think it could be above your skill level to attempt this.

I was always taught, if you take something apart that has a gasket seal, replace the gasket even if it looks good........... cheap insurance and saves you doing the job twice.

Guess your probably right about it being above my skill level. Consider myself reasonably quick on the uptake. Haven't done much....if anything with outboards. Try to break things down into simplistic and semi logical steps. I am researching as much as I can to try and circumnavigate as many problems as possible...... whilst trying to find out what could go wrong/be wrong and attempt to factor in contingencies for these.
Simply put, I am a keen learner, semi practical thinker, father of 3...........and broke!!!!

OK.. in that case.. remove the intake sreens to access the shift rod linkage.
It comprises of 2 nuts joined together (undo these as normal) push the top nut up to expose a plasctic clip ind the split and flick this off the shift rod (don't loose it) The top nut can now be removed from the shift rod.
Undo the 4 visable bolts holding the gearbox on. now remove thegearbox off the outboard.

Thanks for the advice SK. I will give things a go in the morning. Appreciate all the advice and assistance.

How about just removing the thermostat and poppet, could all be clogged from that point, easier to look into too , always apply grease to any bolt before refitting them, good luck

before you remove the leg remove the thermostat and chech it out. remove the screen from the leg( where the muffs go). jam a hose into the hole where the thermostat came out of and back flush it this should remove the sand also jam the hose over the outlet for the teltale on the head and backflush(may have a blockage in the corner near the outlet) I have done this to mine heaps of times ond works 99% of the time.( the thermostat is in a little 2 bolt housing on the side of the head. If all else fails remove the leg and check the water pump and repeat backflush. Just remember when you refit leg have it and the selector in the same gear or you will get stuck in forward gear. Its not that hard and it pays to know how it works because one day you might have to do it yourself. hope this helps

Thanks for the insights Dreemon and Bicko1. The information and suggestions I have gleened today will hopefully prove invaluable.

I'd say you've got a disintegrated impeller caused by blocking the water flow in the sand. If you havn't tackled an outboard box before maybe you should get a book for the engine you have. Apart from gaskets and other little tips there is probably a procedure to ensure that the throttle and gear selection syncronisation is set correctly when re-assemled.
Get a book if you can and it will pay for itself in a short time.
Hope this helps.

SUCCESS!!!! At least as far as the telltale is now pumping water. Reverse flushed as suggested and water is now flowing through the telltale. Not suggesting that this is all my worries over......I realise the potential for other damage is real. I flushed the motor for about 7minutes and there didn't seem to be any apparent overheating :D:D. Fingers crossed that this was all that was needed......guaranteed that I won't be travelling far from home till satisfied things are right.
To all contributors to this thread...........THANKS. Your input has been an immeasurable help, and is greatly appreciated. It scares me what the accumulated knowledge base for this site is, and that is a direct reflection on the site owner and you guys/gals.......without your contributions there wouldn't be a site.;D;D;D
Cheers
