Brown Water in Motorwell

I have a 170 Montauk and I notice that the next day after I wash the boat there is a dark brown liquid in the small pocket in the motorwell. I was wondering is that water coming from the drain plug hole? By the way that brown water smells really bad. Does anybody have a similar problem?

I don't know if I understand your question exactly but the drain-plug hole as I see it is not connected to the motor well. Do you mean the two draining holes in the motor/splash well that go out the transom?
What does the brown water smell like? Does it have a greasy feeling to it?
Btw, welcome to the forum.

Time to check a few things.
My experience has been that brown water leaks out of rotting floorboards.
for instance, I have a soft spot in my floor up near the console...the original seats were replaced with a leaning post and one of the original screw-holes does not have sealant in it...when I wash the boat and then stand on that part of the floor, brown water oozes out. I spent considerable time this summer using a rag stuffed into the hole to "wick away" the moisture as much as I could, used GitRot and then re-sealed all of the holes.
I also had brown water oozing out from around the bow rail mounts...I completely removed the bow rails, dried the holes, drilled new holes (oversize) and patched everything with Marine-Tex and re-installed the rails...no more brown water.
I still experience brown water in the bilge if I over-fill the boat with water and allow the floorboards to become wet again.
I consider this to be a serious problem and one that causes me concern.
Check your floor for holes and check your drain plug to make sure it is intact and the rubber o-ring has not rotted away.
Finally, remove your sump cover and repeat the test to see if it is simply coming from your wooden cover.
I hope this helps...that brown water is coming from somewhere in the boat where it is contacting wood...find it.

I have noticed smelly, brown water before in the bilge areas of boats - especially inboard boats. In those cases, the smelly water was from grease and oil getting mixed togther with water that happened to get down in the bilge.
I'm grabbing at straws here, but is it possible that a small amount of water is getting into the cowling of your outboard during rinsing, coming in contact with grease or oil that may be placed on different areas under the cowling at the factory for protection, and then the smelly mix leaking into the motor well? Or maybe even water somehow getting into the small, grease-filled cylinder that the steering rod travels in and out of, and leaking out.
Sorry for the run-on sentences.

I get some "brown water" in my motor well as well...
after I wash my boat but
it doesn't puddle up like yours. Looking at the well,
I get brown water running down lines on the motor
side wall of the well. I am not 100% sure yet, but
I believe it's corrosion from something there.
I just washed my boat today, I'll take a pic of mine

I Don't think anything is rotting the boat it's still new I only have about 60 hrs.on the boat. I see a brown stain on the inside of the of the drain plug hole facing the motorwell.Was wondering if the water is coming from the in side of the transome and into the motorwell.

Do you keep the boat outside?
When my boat was outside overnight, the next day
I found some brown liquid on the corner of the boat.
I suspect the cat or something jumped onto my boat
and peed there because I saw some footprints.

I notice the same thing on my boat too. It has occured since I bought it new. I just wipe it out with a rag. Maybe it's an Oahu thing. I live in Kailua.

Sounds like a CAT thing. Ewwwwwwww.
Mines is in the garage. Did not encounter this brown liquid.

It's common to have some brown marine grease ooze out of the zerc fittings and into the motor well when the zercs are over filled, which they usually are. In full trailer tilt the Merc 90 ELPTO will leak 2 stroke oil out of the carb and into the motor well (run with the fuel line disconnected for a minute to drain carb and stop the dripping). The oil cap has been known to leak as well (partial filling or replacing the gasket is the solution). If your boat is slipped there will always be water present in the splash well below the transom drains which can grow algae, collect bugs, leaves etc. Regular cleaning of the well along with the bilge sump is normal maintenance for my 2003 Montauk 170.

I know where the water is coming from.
Went fishing today after bringing home the boat looked in the motorwell. The water is coming from the plastic sleeve inside of the drain-plug hole. Was wondering if water is some how getting into transome through the sleeve.
Might be a warrenty issue, will call dealer on Monday, or might just patch it with some 5200 when it dries.
Hope the 5200 sticks to the plastic sleeve.
Maybe I'll have to repair all of the drain-plugs.
Does anybody else have the same problem with there Drain-plugs.

Is it brown or redish brown? I had a redish brown ooze coming out around the drain holes on a 94 Dauntless. I beiieve it was some uncured resin leaching out. Never did anything but wipe it away, boat is still like new, no soft spots, no issues.

Redish Brown, but it's water not ooze. It might be uncured resin. I'll seal it see if that works. Thanks

I can't believe there would be any uncured resin. If there
is, Whaler has one heck of a quality control problem.

I have seen brown water discharge from fiberglass laminates which contained imbedded wood reinforcement. I had a hatch where the laminate cracked open and the wood inside was getting wet. This gave a discharge of dark brown water. The cure was to:
--open up the crack
It would be unusual to find this type of problem in a boat only a few years old, but that is not to say it is impossible to happen.

I e-Mailed Boston Whaler yesterday about the brown water in the motorwell, they emailed me right back !!! What Service !!! They said could be the sealant around drain plug might have failed and said to bring the boat in to the Dealer and have the drain plug re-sealed or replaced. Anyway thanks to all for their help.

oahuwhaler, I've had my Whaler serviced at Windward Boats under warranty twice. They do good work and do it in a timely manner too. I'm sure they will fix it right.
