water discharging from several places on lower unit

[monstertails]

I just replaced the water pump and lower unit seals on my 1989 force 125 and it passed the pressure test without issue. This is the first outboard I owned and ran it today on earmuffs in my driveway. While running I noticed water discharging from several little places other than the exaust port on the L/U and also pushing up through the hole where the gear selector rod is. My question is, is this normal? It appears to come out of 3 little holes on either side of the drive. One other quick question can you add aTemp. guage to this motor?

 

[jerryjerry05]

Yes on the temp gauge.
But a gauge isn't the best option(my opinion).
I install a car or motorcycle horn instead of the buzzer.
You don't monitor the gauge and it can overheat.
Frequently test the system.

The water coming from different places?? Could be the seal between the shaft housing and cowl is leaking?

If there is no exhaust fumes under the cover?? then no problem.
This pump is designed to supply way more water than you can use, so a couple leaks won't hurt.

Thanks, I like the horn idea!! As far as the water leak, maybe if I post a pic someone could help me track down the issue, I know a few leaks are ok but I have a weird issue with things not leaking. I am getting warm water out of the exhaust and a little bit spraying out of the 2 little water ports on the shaft housing but when the engine is running it’s coming out of the other locations mentioned not just the exhaust.

Here is where the water is discharging. It almost looks like it should and it only does when the engine is running.

 

[jerryjerry05]

Drop the lower unit.
Check the seal on the top of the pump?

See if the pipe is connected and not cracked or has a hole.

Then hook a hose on that pipe, turn the water on LOW pressure.
Flash light, look up inside and see where the water comes from.

Those 2 holes in the first pic are drain holes to drain excess water.

I just replaced the water pump and water pump housing with a new seal, is there anyway to check the seal other than visual inspection? So the water discharging from those holes in the photo should not be?

 

[Nordin]

Yes some water should discharging from those holes, they are as jerryjerry says draining for the part of the LU that contains water when runing.
The holes are in the same part as the exhauset port at the LU because cooling water and exhaust are mixed when leaving the engine.

OK I pulled the lower unit off and attached a hose to the water pipe running up inside the housing and turned my garden hose on low, I had a good stream of water discharging from the exhaust port and no cracks or leaks as far as I could see in the water pipe running up inside the housing. But prior to this I ran it for 15 minutes on the earmuffs and monitor temperature temperature never went above 123° on any of the cylinders. When I remove the lower unit I noticed the driveshaft was soaking wet as if water from the water pump was spraying all up inside. Is this normal? I will include more photos of these little holes from inside Lowered unit looking down. I was concerned when I noticed all the water on the driveshaft.

it appears that where the water is coming from is separate from the exhaust area. also I am quite concerned about the driveshaft getting wet. Is that normal?

I have a 1978 Chrysler 85HP and it discharges water exactly like yours. It has done that for as long as I can remember and never had any problems. I always figured the water was coming from where the water tube inside the lower leg pushes into the nylon fitting mounted on top of the impeller housing. There are no threads or sealant, it just slides into that fitting when you reinstall the lower unit. So how could that be a water tight connection. especially when the pump is creating a lot of pressure? Just my 2 cents.

 

[monstertails]

I Appreciate everyone getting back to me with all the info,I was just concerned with the driveshaft getting wet and all. I guess with the engine running at 123° for 15 minutes on ear muffs should tell me that it’s getting enough water.I guess I will just hook the lower unit back up, install the recommended telltale and ENJOY IT!!!!:joyous:

 

[tg3690]

And like jerryjerry05 said in post#2, the pump supplies more water than you can use anyway, so if it leaks a little at that connection it will just drain out of the holes in your pics. IMO

Even BETTER than a horn is a relay that kills the motor when it gets hot. Easy enough to wire, whether you have a "battery" ignition where you energize the system, or the "kill" type. All you need is a 5-terminal relay so you can either KILL by connecting the kill wire to ground when the relay is grounded through the temperature sensor, or BREAK the circuit to the old Motorola powerpack or optical trigger when it's grounded. If you can clear the cooling system obstruction and you want to start the motor up and cool it down, you can defeat the relay. But, nothing like the motor telling the operator "I'm Hot and I Refuse to Run Any More!" to get his attention - BEFORE said condition is a result of seizing up!

 

[monstertails]

That would be a cool Fail safe too.

Not sure I'd like my motor to quit when entering Sebastian Inlet.

 

[tg3690]

I installed a red LED indicator light near my temp gauge on the console. Just wired it in to the warning buzzer. When the buzzer goes off the light comes on. Gives you audible and visual warning and was very easy to do.

 

[monstertails]

Nice!!

Not sure I'd like my motor to quit when entering Sebastian Inlet.

lol, remember how I came up with my version of overheat warning; by using the thermo-switch to give the kill-circuit it's ground.

I ended up doing exactly what Topgun3690 did

I would guess you're not getting a good seal where the water tube goes into that plastic piece coming from the pump. You should've gotten a new one with your impeller kit, but I would find a way to tighten that seal up just for piece of mind. You're not overheating so it shouldn't be an issue, but it will make you feel better lol.

You run in salt water?
