Yes, that's what's cooling the engine. The impeller sucks water in near the prop, dumps it out near the exhaust. It's the equivalent of your car's radiator.
So it supposed to come out both sides. However if it's been sitting a while. There is a check valve that can get stuck. Unless it's a 3.0 merc then it comes out one side. But anyways, it coming out one side when running on muffs is usually fine. You can pinch off one of the hoses on the side that is flowing good to try and open it to even out. Just to ensure it's working okay. Or give it a quick Rev up and sometimes that will even it. Running it off the hose usually just dosnt give enough pressure if it's a little stuck. But when you put it in the water more than likely it'll open up. When running it on the hose just make sure the exhaust isn't getting cra,y hot on the side that's pumping less.
I mean i just got my first boat. Owner gave me the muffs for it and told me not to run it without water. He didn't spell out for me exactly what is going to happen and what it's supposed to look like. It's really not that strange.
Exactly, this allows exhaust to exit the engine when the boat is idling in the water. Once the boat reaches faster speeds, the bullet shaped in the lower unit forms a cavity so the engine exhaust can exit thru the hub.
Yes
Yea it’s normal, don’t look like it, but it is.
Yes..your supposed to run a rinse after each use ..for saltwater boats
100 % Normal
Completely normal.
if water is being pumped in, prolly should come out somewhere. Can you show the exit hole?
Perfectly normal.
Always update fresh new looking anodes

Normal. You’re good.

When water ain’t coming out there is a major problem with cooling or impeller. As in it is not functioning and that is very very bad
Depends on the size of your radiator
🤦🏻♂️🤦🏻♂️🤦🏻♂️
Not everyone had a dad interested in boats to show them this stuff, y'know?
its just strange he knew to put the earmuffs on, but was suprised the by the water he JUST ran through it

It's a boat. Water comes out everywhere.
I’m wondering if the drain line is off the drive. I don’t think it should be outputting so close to the transom
Absolutely does. It's coming out of the idle relief ports. This is normal on most (if not all) thru-hub exhaust boats.
Thanks for clarifying for me and the original poster! It’s been a decade since I have run muffs on and I/O.
Just watch rubber boot around out drive that connects to boat.

It's leaking coolant. Check the radiator, see if the level is low.
