Any idea what is the zinc matching the Seakamp 200420 heat exchanger?
Seakamp just replied to me ​”¼  npt thread zinc is 1.7 inch”
Checking on the catalina36.org association, I got recommended size E0 from this site.
They also have a page for the kind you screw into the brass cap – but you may have to cut that to length.
Anyway I had to cut to the length even the E0, as soon as it was inserted the water was not able to go through anymore.
Since day 1 we own the boat, the sherwood water pump was leaking a bit, it was never the top issue but always something bothering me. In this article we are going to go through:
It took few hours to go through this work, but everything was pretty straight forward.
Here couple of pictures from June 2016, 2 weeks after we took delivery of Hotel Catalina.
Based on this pictures we can saw this leak has been there for a while by the rust we can see on the engine.
It has been now over 1 year we own the boat and it’s time to tackle this pump leaking and clean the rust on the engine block.
Here are few of the options to complete this task:
After looking online I found a very good deal on the N202M-908 at pump and parts online. Let’s go with this solution!
Here is the invoice for the pump:
This step is unrelated to the water pump, but it was way easier to complete since the water pump was not in the way anymore.
New hose installed!
Now time to fill the radiator with new coolant! Last time was replaced was last year during the heat exchanger failure.
The service from https://www.pumpsandpartsonline.com/about-us was very good! Few days after the order I received the part as expected.
It’s the first time I try that, I decided to pick white to be able to see if any leak happens in the future. The result is pretty good looking. Next time I have a chance to remove the belt, I will definitely do more painting.

The 2 cabin boards near the engine came with the boat in a pretty bad shape, they were in need of some love. I decided the risk was very low to exercise my varnishing skills on these boards. The result happened to be way better than I expected.
Update March 2019. After this rainy winter and couple of leaks, it’s time to do the forward cabin floor board.
Update March 2019. I replaced CitriStrip with Klean Strip for the forward board, way easier to apply.
Start with 4 coats of clear coat of epoxy. I usually apply the 4 coats of epoxy in less of 48 hours.
Continue with 4 coats of undiluted Epifanes Varnish.
Update March 2019. 2 years later the Epifanes Varnish was still ok, but added a bit of mineral spirit before to apply it.
On the way back from Catalina, it’s time to clean the boat after 4 days to the island. I check the bilge and realize a bit of water is there, pull up the switch to run the pump and nothing happen!
Corroded wires, after some troubleshooting and wiring the pump to by pass the switch, I was sure the issue was the switch.
Quick run to West Marine and I found the pump, of course $20 more expensive than what you can get on amazon, it was for me the first chance to try their new deal to match online price. And it works great!
Few minutes later the new switch was plugged! It’s pretty well done and you can keep the same base, so it’s really plug and play.
One of the item to tackle from our purchase survey! The original bus bar for the AC circuit was corroded. It was a straight forward maintenance.
Less of $20 bus bar from blue sea and some jumpers.
