    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.

     

    Engine high temperature water alarm issue

    After the over heating issue we had last month, the water temperature alarm stopped to work. No sound anymore at the start of the engine.

    After some troubleshooting it seems it was just a ground issue at the engine block level.

    The wire with a resistor broke at one point and it seems to be the culprit for this issue

    Ordered some 1K Ohm 1/2W Flameproof resistors:

    Rebuilt it and it works great now!

    Transmission stiff shifting and control cable replacement

    Over the week-end, we had an issue with the transmission where it was not possible to shift to forward gear anymore.
    Few minutes later and too much play with the gear control, I managed to shear the screw in the shift lever, as you can see in the picture below.

    After a safe back-up to the dock, thanks a lot to the help of Philippe Guillaud and his family!
    It’s now time to fix Hotel Catalina (again)!

    Plan!

    This issue looks to be current with Edson Pedestal (as all other issues before :)), according to multiple comments online:

    So the plan will be to:

    1. Remove the sheared screw from the lever
      1. How? Still need to figure it out
    2. Replace this screw:
      1. https://www.amazon.com/Button-Socket-Screws-Stainless-Quantity/dp/B00YSS9ZAG/ref=sr_1_2?ie=UTF8&qid=1488176791&sr=8-2&keywords=1%2F4-28+x+3%2F4+stainless+steel+screw
    3. Check that the transmission shifts easily by itself to make sure the problem is coming from the control cable and not the transmission itself
    4. Figure out what size of control cables needs to be ordered:
      1. 14′ cable (transmission): http://www.catalinadirect.com/index.cfm/product/1544_841/engine-control-cable-14br-c-270-c-28-c-310-c-320-c-36.cfm
      2. 15′ cable (throttle): http://www.catalinadirect.com/index.cfm/product/1545_841/engine-control-cable-15brc-34-c-36.cfm
    5. Replace the old control cables with a coupling nut (10-32) connecting the old and new one:
      1. http://www.ebay.com/itm/1JA51-Rod-Coupling-Nut-Grade2-10-32-Pk10-/381002901460
    6. Give some love to the engine parts who need a bit of painting:
      1. metal treatment: https://www.amazon.com/Ospho-605-Metal-Treatment/dp/B000C02CDG
      2. paint: https://www.amazon.com/gp/product/B002JG01VQ/ref=ox_huc_add_on_msg_title_1?m=ATVPDKIKX0DER
      3. Protect the fuel line from chafing, not sure how I missed them during my last chafing protection mission.

    New priority project on Hotel Catalina! Let’s see how many week-end will I need to get it fixed 🙂

    Helm tear down and fixing

    Most of this section is coming from this document from Edson Marine. Edson Marine has been very helpful to answer my questions about the different part numbers I was not able to find around.

    Remove the broken screw in the 960-A-938 lever assembly

    During the issue the screw broke and the gear handle got free:
    Easier than expected! I was able to get it out pretty easily with an easy out screw extractor after I drilled a small hole in it with a 1/16″ cobalt drill bit.

    Remove the compass

    The 3 first ¼”-20 x 3 ½” ¼”-20 x 4” stainless machine screw came out very easily and of course as usual one didn’t come at all after a lot of drilling and one drill bit broken I succeeded to get the compass out with only one screw to replace!

    At the beginning based on documentation and online information I ordered by mistake 3 ½” machine screws where needed 4″ long screws.

    I just had to send a quick email to edson to be able to order the needed screw on boltdepot.com.

    Those screws are 8-32 pan head machine screws 3/8” long.

    Remove screw holding the cable holder

    I was doubtful about this part since it looks tedious to get it back there. But it was not as bad as it looked.

     Now I am done on removing the different pieces on the pedestal side, I need to see how it looks on the transmission side.

    New screws from boltdepot.com arrived

    Cables replaced. Time to put everything back together at the pedestal

    Now at the engine

    Machines Screw too small for the housing!

    First I went back with the old one before to replace them later on.

    Compas LED crimping for easier removal next time

    Everything is now back to normal!

    This project took me 2 week-ends, and some painting at home. When it happens I thought it will take a lot longer, but it got fixed pretty fast.

    M25XPB Water pump replacement – Sherwood vs Oberdorfer

    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:

    1. Replacing the water pump
    2. Replacing one of the old cooling hose
    3. Touch up painting of the engine oil crankcase

    It took few hours to go through this work, but everything was pretty straight forward.

    Original state of Hotel Catalina

    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.

    Time to fix this leak and give some love to 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:

    • get a rebuilt kit and fixing it (tried it, it was worse!)
    • new sherwood pump (very expensive and not so much good feedback on the different forums)
    • migrate (upgrade?) to Oberdorfer
      • Replacing with an Oberdorfer pump that has the base that goes on with the same clip system as your Sherwood pump (more expensive, but more straight forward replacement)
      • If you aren’t scared of, rework the base of the Oberdorfer bolt on pump so it bolts into the pump land on the engine (way cheaper, but a bit too involved in my mind)

    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:

    Replacing the elbow water pump hose

    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.

    Old sherwood pump, old hose and old clamp. Everything will be soon replaced.

    Tried to clean and fix the sherwood water pump, but the leak was always there.

    New hose installed!

    Now time to fill the radiator with new coolant! Last time was replaced was last year during the heat exchanger failure.

    Now the hose has been replaced, let’s replace the water pump!

    The service from https://www.pumpsandpartsonline.com/about-us was very good! Few days after the order I received the part as expected.

    I was not sure about the purpose of this hole, and asked online I realized it was to make sure in case of leak of the pump, the raw water has a way to exit somewhere else than in the engine.

    Now it’s time for some painting touch up

    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.

    Pump installed and running!

     

     

    Temperature is good!

    v-berth insert fix

    The Catalina 36 V berth is laid out with one large V shaped cushion and a separate insert to fill in the Vee area attached to an upholstered board that fits/rests perfectly onto the trim of the berth. Invariably, just as we become fast asleep, the insert falls to the cabin sole. Since our plan is to sleep on the v-berth to enjoy the nice custom mattress who came with the boat, it’s time to fix it!

    The solution was to put some velcro tape:

    I had to staple the velcro tape against the insert (update: so far after 5 months it still hold perfectly to the v-berth).
