Please help

Any help would be greatly appreciated. I have a 2019 Yamaha 212x. Today I was at the lake with the family. Towards the end of the day we decided to head back and the left shaft started making some noise. The engine revs up no problem but there's not any real power to push the boat and it sounds like something is rattling. Took the boat out of water and checked to see if anything was wrapped around the shaft. The shaft was free and clean of any debris. Took the boat home connected the hose and no rattle noise, went back to the lake and put it in water, no noise while at low RPM. As soon as I increased speed the rattle noise came back and no power from that side. I hope I was able to explain it correctly and I truly hope someone can point me in the right direction. Thank you

Did you check to make sure the plug on that side or both sides for that matter are secured and seated properly?

That happened to me last week, and it was a small stick wedged inside the impeller. I know you said the shaft was clear, but did you check the impeller ? The rattling you are describing could be vibration from cavitation.
Good Luck,

Good Luck,

This guy was seriously stuck, couldn't budge it from the water. Had to get it out on the trailer in my driveway. I haven't been out since, and hoping this was the cause of my issue.

Yup, almost certainly one of the two above suggestions. Small item stuck in leading edge of impeller or plug not seated.

Please post your results!

Yes I checked it seemed sealed to me. Unless there is a specific way to verify.

Wow. I already checked but I will have to get a better flash light and try again. Thank you

I will have to check again. Yesterday I didnt see anything. But at low rpms it does push water only once I get past the no wake zone where I throttle up more it does that

How did you get it out?

It's explained in the FAQ section. Very easy.

Even if you can't see anything, I would recommend pulling the impellers anyway. Sometimes things fall out that you can't see. This has fixed this issue for me quite a few times.

Do you know if there's an instructional video or step by step to do this anywhere?

How did you get it out?

I used some long needle nose pliers to work it side to side. It also helps when I bumped the engine to move the impeller to another position. I didn't want to take the intake grate off if I didn't have to. I also worked slowly, since I didn't want to damage the impeller during the removal. The suggestion to pull the impellers is something I will do next if the problem hasn't been taken care of.

 

[Flaviu88]

Found the problem. Piece of wood got stuck in there. I tried to remove it with needle nose plyers but no luck. I will have to remove the back off to pull it out.


Thank you so much you guys are amazing.

Nice! You’ll want to be aware of what it sounds/feels like when something gets sucked up and how to spit it out while not having to ruin your day taking the boat out of the water. For me, I throw it in reverse and try to spit it out. Others turn off the engines first and then throw it in reverse and try to flush it out. Search the forum for how this works.

 

[sunbyrned]

Oh yes, one more thing I do. I try not to idle. That’s when things tend to get sucked up for me since the boat isn’t pushing debris out of the way. If I have to stop for some reason, I just turn the engines off. Just a thought.

I tries to do that but it didn't work.

Thank you for the information, I'm learning all new things. We just purchased this boat 3 weeks ago so any advice is extremely welcome
