SX190 HELP

About to do an oil change on my 2013 SX190. Hooked the hose up to the flush port, started the engine, turned the water on (ball valve at end of attachment). Engine ran for a couple minutes, water out the bucket but not the pisser. Then the engine started smoking. No alarms went off, but it definitely smelled burny. Turned off water, turned off engine.

There’s no leak between the flush port hose connection and the engine. Ran string trimmer line all the way up between the pisser and engine. Good to go.

I read that it won’t always piss from a hose source. But the smoking/burning bothers me. Does the clean out port need to be in? That’s the only thing different from my driveway versus being on the lake (other than being on a hose) but I can’t imagine it’s necessary for it to be installed on a hose. I don’t need that gaping hole to be sealed because I’m not moving.

Thoughts? Gonna change the oil in the meantime. Should be hot enough!

was it smoke or steam? steam is very common

It was coming off/around the engine itself, and smelled burnt. I’ve seen steam around the bucket before. This is my first time changing the oil, but we’ve certainly been out on the boat a lot and never seen or smelled it.

Edit: we bought the boat May last year from a dealer, it actually belonged to a member here. I know it was very well taken care of and was serviced before we bought it. We put MAYBE 40 hours on it last year. The oil looked really good when I took it out a little bit ago. I let it run a couple minutes again after doing the oil/filter/plug change. Not long enough to let it start smoking again though, got me worried. Still never saw water out the pisser but the garden hose was real soft once I flipped the valve, so likely low pressure. Not sure if that makes a difference.

Was there maybe oil on the engine? Like spillover from filling? Looks like you had not yet changed the oil, and had run it a bunch last year, so would not be left over from the last change...

Yeah this was pre-change, just trying to warm the engine up a little before extracting the oil.

That was certainly the first time it had run since the prior fall. Easily 6 months. I did change the spark plugs before firing it up, and I had wiped off the engine cover with a dry rag…I didn’t spray anything in there to clean it, so I don’t suspect it was something burning off.

The high temp alarm never sounded….so maybe I’m making a big deal out of nothing. I know the water hook up was working. When the handle was closed, the hose was very tight and unsqueezeable if that makes sense. I fired the engine, opened the valve, and the hose became very squishy. Like I said, plenty of water out the bucket but nothing out of the pisser. So I’m thinking that’s due to a low water pressure issue. But…the clean out port was not in place. I wasn’t sure if that made a difference….and like a dummy, I never put it in to test my theory.

We are planning to take it out next weekend for the first time this year, so we’ll see what happens then.

Update:

We took the boat out this morning, just got back a little bit ago. Strong whiz of water out the pisser, so my issue appears to be water pressure from the house. Everything ran great, no smoking/steam/whatever the hell it was.
