entire pump--less than 3 boat bucks (~ $270).
Did someone change the value of a boat buck? I thought it was $1000. Is this
deflation as opposed to inflation?

On my Beta 28, the pump bearings (on the shaft behind the impeller) also have
O-rings on them on both sides of the bearing and these can leak, especially if
a bad bearing has 'scored' the shaft. In my case, IIRC the shaft was scored
enough that the entire pump needed replacement--the shaft could not reasonably
be smoothed out enough for the old or new O-rings to seal. With a new pump in
hand (or a rebuilt one?), it was a simple matter to replace the entire
pump--less than 3 boat bucks (~ $270). Charlie NelsonWater Phantom'95 C&C 36

body.hmmessage{font-size: 12pt;font-family:Calibri}Recently, I discovered my
raw water pump was leaking during engine operation. So, I replaced the
impeller [old one looked perfect after extraction] and the "O" ring seal.
After renewal of impeller and "O" ring, I ran engine about 2 to 3 hours, and no
leakage was observed.
However, yesterday, it was leaking at about 10 to 20 drips per minute while
motoring.
Are these pumps similar to an automobile water pump? That is, when the auto
pump's bearing fails, it starts to leak?
Is the leakage telling me that I have a bad bearing in this pump??
Thanks,
Pete W.
