I had a bit of temperature creep at WOT over 5 mins. Started heading to early 90s C but the other engine didn’t so time to clean coolers.
The Kad42 has 3 coolers with heat exchanger and oil cooler being a bugger to reach.
Set about coming up with my own pumping system.
Parts need:
5m of 32mm corrugated pipe : UNIVERSAL Bilge Pump Boat Hose Corrugated Flexible Filter Pipe Marine Flexi Tube https://rover.ebay.com/rover/0/0/0?mpre=https://www.ebay.co.uk/ulk/itm/381699414337
£11.39
Bilge pump : 1100GPH Marine Bilge Pump Submersible Water Pump 12V Electric Yacht Boat BP001 https://rover.ebay.com/rover/0/0/0?mpre=https://www.ebay.co.uk/ulk/itm/323601141159
£12.99
Container (free)
A few jubilee clips
30mm diameter (approx) solid plastic pipe (cut up an old hoover handle tube ) I used a short section on the end of the corrugated tubing so the jubilees on the engine hoses have something solid to clamp onto
So, connected the bilge pump and 3m of tube to the seawater pipe at the exhaust elbow. Connected the other flexible pipe to the seawater pipe engine side of the strainer. Filled the container with fresh and started the pump to push out seawater into the bilge.
Added the rydlyme to the container with as little freshwater as possible given the circulating volume in the engine coolers and the 5m worth of pipe.
Fizzing away nicely :encouragement:
Circulated for 2 hours and all done as below. I don’t have before pictures as I didn’t plan on taking the exchanger end cap off however, it removed something as once all back to normal, I had a drip! Already had a new O Ring so all fixed now and good opportunity to see what had gone on
As it went on I could definitely see the flow rate improve and the bilge pump “note” change.
Out tomorrow so will see what happens but still.....very worthwhile job done
