Most likely he has an engine mounted water pump with a thru hull
pickup. Bravos not the same as alphas.

I'm not sure if the Bravo is similar to the alpa1 or not, but I had the
o-ring on the water pick up port go bad and had the exact problem.
When the engine was running, it was actually pumping water into the
main bellows and filling up the bilge. When the motor was not running,
there were no leaks. It would also pump a very small amount of water
through the shift cable and onto the top of the motor.

Has the out drive been removed recently? If so, maybe the o-ring is
pinched....

Bravo One Experts: I have water leaking into my bilge when my engine
is running. It's coming from the lower part of the transom plate where
the exhaust lines meet and go out to the discharge ports (as best I can
tell). Any idea what it is? Thanks.

I had the drive off the replace the engine, but is water is warm so I
don't think it's coming from the pickup. Never the less I have to pull
the drive to get the engine out, so I'll be sure to take a look at
everything very closely. I'm hoping it's just the Y pipe gasket that
Jim was talking about. If not I'll have to break into the ole piggy
bank again. Thanks!

Used Y pipes go for under a $100 on ebay all the time. Anyhting for a
boat that's under a $100 is a bargain :-)
