Replacing the raw water pump

[SV Hope]

I plan to replace my leaking Sherwood G 65 raw water pump with a new unit this weekend, and when time permits rebuild the old one and keep it as a spare. I have read in previous posts about the importance of " turning the engine over several times without starting it " so that the two shafts can be aligned correctly. I have three questions

1. Does one turn the engine over by hand ( and what tool is used?) or start the W 40 up but have the stop lever pulled out?

2. Is there a way to make sure that the two shafts have mated correctly?

3. Is it unwise to paint the pump?.

I am a first timer at this. Thanks in advance

If memory serve me right, I believe there is a Service Bulletin out regarding this very topic? I bet Garner has a copy?

I'm not much help on doing the project, because I have never done it, but Randy is right, Garner does have a copy of the service bulletin on his sailing sea dragon site.  It's the first one under the Westerbeeke service bulletins under manuals.  Service bulletin number 10.  It also talks about getting the end clearance right. 

Replacing the impeller and/or a rebuild is on my list as well

Michael,

it is a very simple procedure. here are your answers:

1.  Be careful not to tighten too much the water pump nuts. you should be able to shift it by hand. but not too lose either so that it slides down with gravity.
Then with the fuel shut off (with the lever), start the engine (it will not start obviously but turn over) for a while (like 10-15seconds or so  should do it).

2. refer number 1. i guess if you can identify where exactly the old one was ( hard because you should clean the flange on the engine), the new one should be in the same place.

3. it is bronze I believe, so no need to paint.


good luck

Hi

Zaya, Della and Dave, Randy. Thanks for your input. After reading service bulletin #10, I was starting to convince myself that the task was beyond my level of competence. However, I am feeling more positive after reading your reply Zaya. If I never post on here again, it means things went horribly wrong, I jumped overboard and am living like Robinson Crusoe.

Cheers

So Robinson, is "Friday" good with mechanical things like raw water pumps?
