F200 Lower Unit Leaking?

[tprice]

I have a F200 with less than 75 hours on it and today while doing yard work(instead of fishing) I noticed a small spot under the lower unit. It

caught my attention and when I investigated it was actually a very small stream coming from the UPPER screw (not from the prop, I have had that before on my old motor).

Motor was tilted down and was also serviced back in the fall as per Yamaha and by a certified mechanic.

I wiped the stream off, raised the motor and checked everything else and lowered it back down and nothing else ever came out.

What could have caused this, I was thinking maybe mechanic overfilled lower unit and due to hear(91 today) maybe it expanded a little but still I think it should not seep out.

Ran the boat good bit last weekend fishing 3 days straight and this was the first I have seen of this and motor has been in down position all week

I'd guess the same as you but would want a more technical answer (which I'm not qualified to give). But since you get what you pay for, I would definitely pull out the top screw and see if any additional lube comes out. When the engine is sitting level, the fluid should be up to the level of the top screw. It's cheap and easy to drain the lower unit fluid, it may be worth doing just to make sure you don't have any problems. I would also pull the prop and check for fishing line. Fishing line can cause water instrustion through the seals which is a bigger problem. Hopefully your mechanic just added a little too much.
