Vent hoses and stanchion hose barbs don't cause lesks, PEOPLE cause them!!

The deck thru-hole simply reveals you have a problem that could have been avoided!

Quote from: Allatsea on July 08, 2024, 06:11:02 PMHi Craig,
I'm most interested in how you confirmed it was the guage, as I am currently dealing with exactly the same symptoms as you.


Have you gone thru the Teleflex troubleshooting guide steps for the temp gauge?
What other troubleshooting steps have you done?

Quote from: Analgesic on July 12, 2024, 04:22:10 AMMy usual auto parts store doesn't have the radiator cap pressure tester to loan/rent.

Usually Advance Auto, Autozone, O'Reilly and sometimes NAPA rent them.
Harbor Freight sells a kit.

Or, buy a gauge, bicycle pump, and a couple pipe fittings and test thru the thermostat cap.  You'll probably want a valve in line to isolate the pump once you pressurize the system because the pump might leak a little.  You also need to know the pressure rating of your cap and not exceed that. I'd buy a high psi cap - like 20 psi - just for the test.

Have you downloaded and read the parts manual for your engine? - It really helps when identifying engine parts.

Have you studied the coolant flow diagram (it shows seawater and closed)  - it can help to ID every place that a hose connection could be loose.

What's your annual PM on the cooling systems on the engine?


If you post good pics of your engine it can often help to ID issues.

Coolant could be theoretically leaking from anywhere there is coolant, including if there (unlikely) a hole in the WH.

Coolant can be lost if there is a pinhole leak between the seawater and coolant sides of the Hx, although it should not show up in the bilge.

Coolant can also be lost if there is a pinhole leak between the potable HW vessel and coolant ("heatant") loop in the WH. It would depend on the relative pressures which way each fluid would be pushed. Obviously it would not be good, as (there is a very slight chance that) toxic coolant could be pushed into the potable water supply.


That's a Shurflo 170-061-29 strainer that is NLA.  I suspect it was discontinued when Pentair gobbled up Shurflo along with everything else now under that umbrella.

You might find that a tiny skim of SuperLube on the o-ring might help make seating the top easier.  Otherwise replace it with the current hi-hat strainer.

Yep I know that

"Yes."  Thanks!

Hey Jon/Ron

THANKS!  Got it.  What threw me was that I was envisioning Ron using the PAR to pump from a jug of 50-50 INTO/through the closed system.  That method will work well for the issues on my mk-I -- the WH is high (in the cockpit sail locker) and that's where air in the closed system ends up.

So the PAR procedure sucks coolant from the closed system pump, thru the WH and depends on gravity for coolant to flow from the Exh Manifold, through the Hx, block, and back to the TSTat. 

Since Brian's issue was that the airlock was located in the pump, have you ever found that the PAR method won't draw well on a recently drained/filled system because it can't pull from an empty pump? (yes I know that the recommendation is to fill the pump.) 

Just asking, do you think that it would be effective to turn the PAR around and suck FROM the Exh Manifold and PUSH it through the WH?   That would be using the PAR to push coolant into the pump.

I believe the tank should have  90 ell on top for the vent hose. At least that's what my 30 has so it fits under the cubby cover.

Being on the Great Lakes the PO probably removed the macerator, or maybe when she was first commissioned.  Either way, its nothing to concern yourself with (unless you plan on ocean cruising.)
KUDOS!!   :clap

Very nice~

No picture of your hull condition, so "it depends."  I've seen some very cruddy looking hulls. 

If appropriate, before Noah's garni a scrub with detergent/augua solution followed by a rinse down.  Sandpaper and acetone cost 10 times what they ought to and no sense wasting them taking off plain ol' gunk.  Give the wood base the same pre-treatment as the hull (naturally make sure it is competent and not punky.)

A reason to use microfibers is it has very high adhesion property for wood and it is nearly as structural as colloidal silica (which is a pita to mix in.)   

Mix your resin/hardener and pre-brush the hull and wood w/ a light coat to provide a good bond.  Then mix in your microfibers and adhere them together.

  • disconnect the heater hose to the thermostat
  • take the cap off the reservoir.
  • I have a small PAR hand pump the I put into the disconnected hose and pump the coolant into the reservoir until I get a steady stream of coolant.


I am interested in your method -- it may work better on the C-30 mk-1 than "our" method.  The mk-I has some unique challenges.

You pump into the heater hose (i.e., to the water heater)?
Which "reservoir cap" do you remove -- the exhaust manifold cap or the overflow tank cap?
What do you mean then "pump to the reservoir"? (keep pumping to the water heater?)
Where are you looking for the steady stream -- Out the Tstat nipple?

Dontcha love when a plan comes together?  And without blood, cut fingers, and iodine.

Enjoy the light show and be safe.

Epoxy resin/hardener with microfibers thickener.

5% the TStat is stuck. 
95% chance you still have an airlock.  Probably in the coolant pump so the impeller is trying to move air, which it cannot.  Fill Fill Fill thru the top of the coolant pump.

You could try to put a bypass hose between the Pump/TStat housing in place of the WH hoses and burp again.  That might get you on the road for fireworks.
