A few times that I've pulled the drain plug on my boat there has been
red
fluid coming out. It happened again the last time I was out. The lake
is
green and blue.

I took the engine cover off and inspected my power steering fluid level
and
the power steering hoses with flashlight and by hand. No sign of
leakage.

I ran the motor to operating temperature and turned the steering wheel a
few
times; no sign of leakage.

Why do I occasionally get a red fluid coming out with the lake water
when I
pull the drain plug after boating?

The only red fluid on the boat is the power steering fluid and gasoline.
The gas tank hoses are secure and there is no scent of gasoline, except
after dieseling.

Transmission fluid can also be red.


I've checked the engine oil, the hydraulic fluid, the drive fluid, and the
power steering fluid. PS and gasoline are my only red fluids.

Probably not likely on an 18 footer, but if your boat is equipped with
electric/hydraulic trim tabs, the fluid that operates them is red.
Personally, I'd be asking the question of why there is any liquid of any
type in the bilge of your boat. The normal state of a bilge for a stern
drive boat is bone-dry, no water whatsoever. There are only three sources
of water in a stern drive bilge that I can think of, and only two that are
acceptable.

1. Water from the weather (acceptable).

2. Water from a temporary ingress due to taking a wave over the bow or from
dripping swimmers (acceptable).

3. A leak from either the hull or a through-hull fitting, the on-board
water systems, or the mechanical systems (unacceptable).

I think you need to broaden the scope of your investigation.
