Yamaha 2hp exhaust plate

[Benjygardner]

Hi, I have a 2hp Yamaha 6a1 outboard motor. It runs nicely but when it is running there is water spitting out of the hole in the front of the exhaust plate (the thick slab in between the powerhead and the lower shaft) there is enough water coming out of the exhaust so I’m not sure what the problem is. Thanks.

I'd make sure that the six bolts holding leg to powerhead are still tight enough. If they are then don't worry about it.

Hi, they are tight. I have taken the outboard apart and there is drops of water in the lower unit, I have replaced the gaskets and it is still leaking.

By lower unit do you mean inside the actual gearcase where the oil is?

 

[Benjygardner]

No, I mean the shaft connecting the power head to the lower unit with oil.

The photo on the left is where the water is leaking out the engine. The one on right is where there is water drops from the leak

The slot in the first photo is obviously there for a reason, presumably to allow any water that manages to get onto the top of exhaust plate to drain away, I don't think it's a problem. Having said that, I can't recall ever seeing water from that point on my own engine.
From memory, the area you have circled in the second photo is where the exhaust from the engine enters the leg. The cooling water that has circulated the head drops into the U shaped slot to the right of the drive shaft and mixes with the exhaust in the leg. There is nothing. other than exhaust pressure when the engine is running, to prevent water getting into the area you have circled. I suspect it has just drained there when you have tipped the engine back. As such, it's nothing to worry about.
The photos you've posted seem to show everything in good order.

Thank you very much.

Yep entirely normal, don't panic.
Bet you wished you hadn't split the engine now...
