Fuel/oil coming up from propeller.

[patrolcarr]

Im not sure if anyone can help with this one. I have a 2000 2 stroke yamaha 130hp. I got some metal wire(about the size of fishing line)wrapped into my prop and was able to undo it pretty easily by hand. But since this happened I see tiny bubbles mixed with a small amount gas/oil coming up from the water as I'm warming up the engine at idle. After a few minutes of warming up the engine, I have a "rainbow" of gas in the water around the engine. Any ideas?

Re: Fuel/oil coming up from propeller.

Patrolcarr, the rainbow affect sounds normal to me. However, the wire around your prop could have damaged your propshaft seals. Fishing line does this too. The best way to check seals is to drain you lower unit oil. If there is water in the oil, you will need new seals. If oil looks good, your seals are doing their job.
