My 1987 OMC cobra, 175HP IO has developed a leak around the
intermediate housing. I cant seem to pinpoint exactly where as
the water just kind of streams in at a somewhat slow rate, but
fast enough so it sprays around and water is dripping from the general
area of the transom/outdrive. Has anyone had this happen before?
It seems like a solid metal piece where the shaft passes through
from the outdrive to the flywheel. I suspect the shift cable???
Does this move through a gasket of some kind when raising and lowering
the outdrive? Trimming up and down changed the rate of the leak.

I don't know anything about OMC, but if this were a
MercLoser, it would almost certainly be the driveshaft
boot -- the flexible rubber tube that seals between
the intermediate housing and the outdrive.
If you tilt the outdrive all the way up, and fondle the
boot, you may well be able to find a rip.
Not hard to replace, but you have to remove the outdrive
to do it.

If you have power steering, the cooling unit is behind
the motor near the top leftside.
I once had a pin hole leak....

Mike,
Did it leak while running or at rest?

| 1196.4 | Yes- When the engine is running | ALLVAX::ONEILL | Wed Oct 19 1994 12:43 | 19 | |
It leaked when the engine is running.
The power steering cooler is inline with the raw water input
hose that goes to the engine. So while the engine is running
water travels through the power steering cooler on route to the
engine.
During winterization, the water must be drained from the cooling
unit.
The pin hole rupture, and the engine compartment started to fill
with water, luck I was only 50 feet from shore.
Took the unit off and had it fixed....
Has been working fine for the last several years.
