Hi all,
In Georgetown, Great Exuma.
Noticed today that their is a leak from the raw water pump from the
seal between the pump and the engine block. My understanding is that
this means the pump needs rebuilding/replacement.

Again - the drip is not from the faceplate, or other - from the place
where the pump body attaches to the engine block.

What is my best course of action? - I do have a spare raw water pump.

Please advise on the best point by point troubleshooting sequence.

Thanks to all who advise,

Mike.
