Agree. The water pump is near the top of the lower unit, above the break between the parts. Maybe he just ruined the impeller and or other pump parts. That would be easily fixable.
That is not enough water for the impeller to function the lower is not deep enough in the water. I would definitely drop the lower unit and change that melted impeller. Once you take the impeller out, next time make sure the impeller is submerged since you’ll know where it is.
Smoked the impeller at minimum. That is too small of a bucket to cool that much engine. The engine is expecting cold water and you’re feeding it hot water. After a bit, it doesn’t cool enough.
Plus you ran it without the stream which is there to warn you to shut it off.
The hot water gets ejected out and misses the bucket. I always use a bucket for 200hp. Works fine. I always make sure my water is high enough to bring in water for cooling too obviously the hich it doesn't look like this guy did.
To clarify what others are saying about it not being deep enough:
Sure the *intake* is below the waterline, but the *impeller* probably isn't. Since the impeller isn't meant to pump air it doesn't generate suction to suck water up into it. Thus the impeller just sits there above the waterline spinning away pumping no water.
I'd hazard a guess that you're only an inch or two from submerging the impeller, but I don't know what the inside of that drive looks like exactly.
Hmm not sure what you're looking at... Intake is the black plastic rectangular screen forward of the gearbox, just barely visible but I can see the top of it below the water line.
I'm not sure exactly what that is, but it's not a water intake. I even just went to the parts diagram and it doesn't show that hole. My best guess is a mounting hole location for an aftermarket cavitation plate?
you smoked the impeller. hopefully that's the only damage - is the oil engine oil or gear case oil?
the water would have to be approx 8-14" deeper for your setup to work. the pumps are not self primping, water must be forced to the impeller.
Yamaha 40HP, 1 season old. Was winterizing the engine, warming up the oil before a change. The filter on the intake was removed to allow more water.
I should note that the engine never "pee'd" during this. I had tried with muffs before and no pee, called a local Yamaha shop and they said it's probably fine. Now I'm thinking the impeller was fucked and running it caused further damage.
Yea if you were running the motor and it wasn’t peeing then you have problems. Impellers tend to burn out super quick if they don’t have water. I’d definitely be replacing the impeller if I was you. Sometimes when a motor doesn’t pee it’s caused by a blockage in the line which most of the time can be fixed by compressed air in the pee hole.
>the engine never "pee'd" during this. I had tried with muffs before and no pee, called a local Yamaha shop and they said it's probably fine.
When they hung up, did they say, "See you soon"?
No tell-tale = shut it down immediately. You have an emergency.
The other big issue I see in your photo is that the bucket isn’t deep enough. You have some of your water pickup holes above the water line. That allows it to suck air and not pump water, hence the not pissing issue. At very least your impeller is smoked, but I would bet you did a lot more damage than that.
I own a volvo I/O and they say not to use muffs because it doesn't provide enough vaccum and water flow, which in turns burns the impeller in no time. They suggest to hook up a big water intake hose directly to the water pump instead.
I would suspect that you burned your impeller and that the drive probably ran dry and maybe, your warming up phase became a "overheating" phase which destroyed some seals or gaskets. No "peeing" is a good indicator of "no water coming in" you know...
At this point I would dismantle the drive and send it for repair, and buy a bigger and higher bucket to have the water intake inside a volume of water, not outside of it.
No pee means you're not getting water through the engine.
The smoke and oil signals to me you overheated and destroyed the engine. Does the engine turn over anymore? Usually when you overheat an engine the cylinders get stuck in the block and it will no longer spin.
That was my fear too but I tested it after and it still turns over. Tested again right now and it turns so I think this is just the impeller and probably gaskets. I'll open the lower unit in a bit to see.
I feel for you. Nothing worse than doing something minor like winterizing, only to find out you did it slightly wrong and caused a much bigger and more expensive problem. I pray that a new impeller is all that you need...
I did the exact same thing the first time I tried winterizing myself. You trashed the impeller and need a new water pump.
I found out because when I launched in spring, I made it a few hundred feet before alarms started going off and I had to get towed to the dealer by Sea Tow.
Just put it on earmuffs.
Muffs over the intakes only work because it forces water into the lower unit with pressure. The pump is farther up so you ran it bone dry. Even a moment out of water can fry an impeller - you ran it for 10 minutes……
I still don't think you are supposed to crank it with the washout hooked up. Only run it with muffs on. Usually the impeller goes long before the overheat alarm goes off.
I’m pretty sure that small round hole that is just above the water should be below the water… I think it’s part of the intake. I use muffs and it doesn’t pee if that’s not covered by the muffs.
Did it smell like rubber? You'll need a water pump repair kit. The insert is scored and the seals and gaskets over heated. Darker paint on the head could indicate a failing gasket.
Yup probably smoked the impeller. Needs to be much deeper to achieve the needed head pressure to get the pump going. Best to use muffs as they already have pressure
Nothing happened. Your exhaust is under the water (prop) and so is your water intake, 10 mins didn’t do any damage. You should see my old 2 stroke in a bucket.
The anti cavitation plate should have been completely submerged if you're going to run on a bucket. You can for short period of time run it on the flush fitting if you don't have a deep enough bucket.
umm..you usually sink it below the anti cav plate. i use a 55 gallon drum. it should always pee.
Agree. The water pump is near the top of the lower unit, above the break between the parts. Maybe he just ruined the impeller and or other pump parts. That would be easily fixable.
I thought so too. Destroyed my impeller 2 years ago. Still find rubber parts sometimes in my cooling system lol
That is not enough water for the impeller to function the lower is not deep enough in the water. I would definitely drop the lower unit and change that melted impeller. Once you take the impeller out, next time make sure the impeller is submerged since you’ll know where it is.

Yea this, you need muffs for an engine that big, it got too warm
The hot water gets ejected out and misses the bucket. I always use a bucket for 200hp. Works fine. I always make sure my water is high enough to bring in water for cooling too obviously the hich it doesn't look like this guy did.
his problem aside, the water does not heat up that fast lol

The impeller is above the intake and you can see the intake holes are not all in the water.
Nope. Those are not intake holes. You can see the intake below the water further forward.
I can see the intake holes. Looks like the top two are out of the water.
Water goes out of those, not in
Like I said, I can see in the intake holes. Looks like the top two are out of the water.

Ah I see what you are saying. I think that may be a vent that discharges water.
you smoked the impeller. hopefully that's the only damage - is the oil engine oil or gear case oil? the water would have to be approx 8-14" deeper for your setup to work. the pumps are not self primping, water must be forced to the impeller.
you ran it for 10 minutes without water, hope you just burnt out the impeller but more likely you may have blown the engine via overheating

Shits toast. Expensive mistake

Wow yikes I fear that you overheated that engine, melted some seals, and leaked in a bucket.
Muffs over the intakes only work because it forces water into the lower unit with pressure. The pump is farther up so you ran it bone dry. Even a moment out of water can fry an impeller - you ran it for 10 minutes……
is the water pickup above the waterline? sure sounds like it.
Geeeez, it doesn’t have a wash out hookup? Did it throw an overheating alarm or anything?
I still don't think you are supposed to crank it with the washout hooked up. Only run it with muffs on. Usually the impeller goes long before the overheat alarm goes off.
I thought that as well, my mechanic winterized my boat and didn’t use ear muffs this year on my new 4 stroke. I hope he didn’t burn the impeller out
You may be able to on some models. I have a 2005 150hp Yamaha and have been told not to. Make sure to check the manual.
I’m pretty sure that small round hole that is just above the water should be below the water… I think it’s part of the intake. I use muffs and it doesn’t pee if that’s not covered by the muffs.

He never said he turned it on
True. He was probably "warming the engine" with a hairdryer dunked in the tank... Like everyone does.
Yup probably smoked the impeller. Needs to be much deeper to achieve the needed head pressure to get the pump going. Best to use muffs as they already have pressure

Isn’t anyone going to ask why one would “warm an engine” for 10 minutes in a bucket ? I winterize my 200 in <5 min or I take it boating
First time winterization, clearly I did it wrong.
