No pee Johnson outboard

[racerone]

Maybe pull the powerhead and check grommet ( 302497 ) on the exhaust tuner ?-----Correct factory impeller ( 395289 ) installed ?----Correct water pump plate ?----Correct gaskets ?----Water intake screen behind prop checked ?

 

[Crosbyman]

need some straight answers to post # 9

have you inspected the water passage way leading into the pump ?

have you taken the pump body apart and looked under it to allow easy entry of water ?

have you tried looking up the water tube with a small fiber optic camera to check for any kind of obstruction ?
if you send water up the water tube with a hose does water flow seem blocked or does the pee stream becomes OK ?

if you submerge just the LU in a bucket and sprin the drive shaft does water gush out of the water pump reasonnably ?

salty or fresh water engine you did not say !

btw impeller key is in yes ?

It seems it’s time to take a step back and start from the beginning following Crosbymans questions to the T.
If you do this carefully you will find your problem. Unless I missed it we still don’t know where your water level is In relation to the pump on this motor. I’m just curious as to what kind of boat this is on? What size is the transom? Is the motor a short or long shaft? Why not put the motor in a trash can and test on land instead of in the small reservoir?

At first I put it in a trash can at home and I thought perhaps the trash can wasn't deep enough that's why I took the motor and boat to the reservoir I don't know what else to say I've done everything I've taken the cover off on the side that covers the Pistons there's 10 bolts on that cover out of the 10 all the bolts come out except for one and I broke one bolt off I drilled it out I could not get a straight drill into the piece to where I could tap it so I put JB weld in and put a bolt or rather a stud into the JB weld I ordered a gasket put cover back on and put a nut on that part that broke off I've done everything except for the camera up the site tube which I do not have I have run the water pump and a bucket like someone had asked if I had done the water does come out the water pump reasonably well I've taken the head back off remove the thermostat took it back to the reservoir and it did the same thing so I came home remove the head but the thermostat back in and that's where I'm at now

 

[skip44820]

How do I go about pulling the powerhead I'll see if I can find a video on YouTube but I'm not sure I'm capable of doing something like this is this a big job

 

[skip44820]

Let me also mention that the motor puts an awful lot of water out the two holes in the back of the motor I'm not sure if it should put a lot of water out those holes or not

 

[skip44820]

The weather has turned cold here in Ohio once again I don't have a heated place to work on the motor once we get some warm weather I'm going to remove the lower unit once again I'll answer a lot of your questions I have run the water pump in a bucket without it being in the motor and it pumps water well I believe there's an obstruction someplace in the motor itself possibly where I've done some epoxy work I'll remove that cover and check that check the passages I don't believe that I got JB weld in any passages but I'll be sure to look but once again thanks everybody for their input I'll keep you posted

so "lots" of water reaches " the engine ph

did you or not... try to run a stiff mono line up the pee hole as far as possible ?
backfeed water up the pee hole it should flow and come out the back... I would think

did you or not try to push strong air pressure up the pee hole ?

seems air should flow with ease

based on the fact you have "lots" of water out rear end water but not the pee hole there must be an obtruction floating around inside somewhere.

 

[skip44820]

Once we get a little warmer weather I'm going to try to remove the power head to see what it looks like where the copper tube comes up and meets the bottom of the power head maybe I'll see something there that's causing some type of an obstruction but I don't believe it's internally in the motor I've unhooked the rubber hose off of where it comes out of the motor I blew air in that hole I've had that cover off that's the cover that I broke one bolt out of 10 and had the JB weld it in but I plan on removing that cover here shortly to see what that looks like but again thanks

 

[skip44820]

You know it's quite possible that's why I have the motor instead of the previous owner maybe he could not get it to pee properly I have had some motors that had rubber grommets on the top of the tube that goes into the head I'm wondering if perhaps someone didn't put a rubber grommet on this and it's not supposed to be and it's stuck up in the bottom of the power head what's your thoughts on that gentleman

 

[racerone]

To me outboards are very simple machines.-----Should be easy to fix.----There will be an ---AHAA ----moment on this motor I believe.-----Over the years I have learned that often a motor with chronic problems is sold.-----And many folks mess up motors because they can not afford the $100+ / hr shop.

That's a 33 year oldie motor, if was run in salt water for such long years of operation need to remove the entire block from the pan, remove the exhaust cover if having one, the cylinder head and manually clean all their water passages including the ones located under the block, install new gaskets, torque all bolts to their factory specs to cool and pee right...

[racerone]

He clearly stated ( Post #24 and 29 ) that he had the exhaust cover off this motor.

Do you think that the Exhaust Cover it's the only water passage located on such motor, Nope, what about the Cylinder Head and all the water passages located under the block and pan? With the peeing hose removed from the block, tilt the motor fully up, order a WD-40 can, insert the red cannula fully up the peeing nipple till goes no further in, squirt an overdose of the product and let it soak/penetrate for 30 minutes, install the water hose and check if the motor pees back as a teenager...

This type of internal cleaning should be done by experienced boaters, expect to break some bolts while removing them with their associated bummer while removing them...

Happy Boating

[skip44820]

Wd40 sounds like good advice I'll try that tomorrow I'm not sure when I'll get it back in water I'll check the weather forecast

 

[Crosbyman]

must be me but it seems direct answers to direct questions seem vague
and unfortunately the result will be vague until each suspected condition is cleared off the slate for good.

to this day all we know it was purchased in Ohio but... we do not know if it came from Atlantic city ....
were water inlet passages inspected to ensure Maximum water flow.
Is the impeller key in place and the proper impeller used ?

etc...

 

[racerone]

He said he put the thermostat back in in post #24----That means he had the cylinder head water jacket cover off !!!

 

[racerone]

People are shy or do not understand how an answers can help them.---- Answers to a seemingly simple question can quickly solve their issues.----The novice working on his first motor just offers their ideas as to what is wrong.----I learned 50 + years ago to ask the owner what his motor was doing / not doing.-----And to usually ignore what the owner thought was wrong.

 

[Sea Rider]

For me all this troubleshooting and associated waste of time and energy is full of wild guessing answers.. Isn't known till know if it's a fresh or salt motor used for the last 33 years of operation ? Does this motor counts with an internal sacrificial anode located inside any of their water passages ? Having the thermo's housing seen in good cleaning condition doesn't mean the rest of all the water passages are same. An internal crust will screw the whole equation..

Happy Boating​

 

[racerone]

A 1989 model 28 HP does not have any internal anodes.----At least I have never seen one.----Do not have enough fingers to count how many head I have had off !!
