Not familiar with this pump, but supposing that it is derived from an
automobile power steering pump, the leak would be coming from the
shaft seal - that's the only other rational place for a leak.
Replace it. Can you use an automobile type?

Brian Whatcott Altus OK

thanks Brian for you thoughts
from what I have read on line, it may be possible to use a automobile
type pump but the input and out put for the hoses might be in the
wrong place. Even though it may be possible for me to remove the pump
myself, I have decided to take the boat to the mechanic's next Tuesday
and will decide what to do after they have had a chance to tell me
what options they think are availible.
