Ken,
Thanks for the info. Amazing to think about how much folks care about these boats after so many years. They indeed are nonsuch in that they “have no equal”.
I’m new to Soave. She was lightly used for the past 8 years by her PO and maintained by marina mechanics at a well regarded marina… I don’t have details or a maintenance log. I did find a very lightly worn impeller in a plastic bag that gave me some confidence that the impeller was changed recently. My budget is such that I’ll need to do most of the seasonal maintenance myself.
I’d be grateful to hear if you use the recommended maintenance schedule or have adjusted it to keep Sashay ship shape as she ages. Also if you’ve done any improvements that you feel were particularly beneficial.
Back to the pump… Has your impeller ever failed ? Do you change your impeller for preventive maintenance ? If so, how often ?
Looks like as Joe says the pump comes off by releasing the 3 or 4 brackets . The screws on the housing would be difficult to deal with. Just remove the whole pump.
On my boat, I change the oil, oil filter, two fuel filters, and the raw water impeller each spring. That is good for a year, then do it all over again the next spring. I put 50 hours on my engine last year.
I’m sure others will have a different opinion, but its easy remember to do it this way. One less thing to worry about.
The cover on that Sherwood pump is a pain to open because the bolts are on the back. I replaced my old Sherwood with an Oberdorfer N202M-908 with a much easier to access cover a few years ago.
Somehow, I did let my impeller go for too long without replacing (~3 years-- I blame the pandemic for losing track of time). Started up the engine, no raw water coming out the exhaust. Took the cover off the pump, and the impeller looked ok upon initial inspection (see attached pic). However, after removing the impeller, I found that the metal bearing (or whatever you call it) in the center of the pump as loose. So, it was spinning on the pump shaft but was not adhered to the impeller vanes! It was a bit of a mystery for a while, and I wasted time trouble shooting upstream of the pump. Anyway, thought I’d share for the benefit of the group.

Yea, I learned what I “thought I needed to know” about no-seize maintaining my tractor for the past 25 yrs.
Now I’m learning more because of the marine environment… apparently I need to stock a couple different types of no-seize depending on what metals are being bolted in a marine environment.
Interesting to see how the experiences of my sorted past prepared me for maintaining a cruising boat. Still lots to learn.
Thanks for answering questions for me and folks in the group and steering us in the right direction in our sailing journey.
