Vira - Sailboat rebuild, Irwin Citation 34

Engine Installed heat exchanger. Decided to mount it above the wet muffler keep it as close to engine as i can and mount it leveled and keep it high enough to make air naturally run out of engine. To install it there I made a  mount and screw it to the engine compartment wall. 2 hours to put it tight, but stand off of exhaust.I have about 2 inches clearance from wet exhaust hose. Little straggle to find place for coolant expansion tank. For now I put it to the wall little bit right from picture view area. Connected transmission control and engine stop cable. adjusted idle RPM and accelerator cable to do not interfere with idle speed screw.  Temporary installed engine monitoring controller.  Controller designed to collect engine data and transfer to SignalK server. Then I will be able to indicate all on the cockpit display. For now it is very important to monitor engine temperature to confirm the engine is working without overheating and thermostat works correctly. I plan ...

 Engine Preparing engine to travel. Engine secured  to dolly. 3/4 plywood "skid board" mounted at dolly foot. 7:30AM came to marina. Assembled the crane, hoisted engine and moved car out. Good buy my crane, crane was made from 2x4  and 4x4 posts. Worked well for me all time I worked on engine. I decided to "donate" it  to the marina community. Engine waits to descended. Descend in progress.  Two cars used.  Rope tied to engine, goes to pulley on the to of the hill. (block mounted on the car hatch),. then rope goes to second car. Second car controls rope tension.  To slide on stairs we used 4 boards. 2 at time. Came to the boat, chain hoist set on boom to load an engine. In a process of hoisting Engine is on the boat! Lowering it in the engine compartment. A lot of effort to put it on the place, but we have done it ! Engine is at home ;-)  

 Engine  Still working on fresh cooling conversion. A lot of learn, check, try, source, return (thanks Amazon), weld, paint, try again.   LINK TO FULL REPORT IS HERE   Engine assembled and run with  dual cycle cooling system.   During test run digital temperature sensor showed 68C maximum on free run engine for an hour. Technically, without load i can't get engine to produce enough heat to run thermostat fully open. Partial opening makes to cool enough. More testing will be done on the boat. Hope for better;-)   Also I found one overheat sensor 95C tripped alarm during the engine test run. Other did not tripped at all. Tested first one in the bucket with water on the stow,  it is tripping about 65C, however it marked for 95C. Second one did not tripped in oil bath up to 150C - likely it is not an ALARM switch.    [update] Custom water manifold replaced with T connector, it gave me an inch to lower thermostat ant top hose. Engine mount p...

Weekend off.  I lost previous weekend because stuck in business trip. No post sometimes means nothing done,  Air conditioner  Since I took engine home I had a problem.  HVAC water pump was not able to start due to waterline appeared below pump level resulting water run out of pump. As soon as pump ins not self priming it did not work. To fight the situation I added  check valve near AC water discharge preventing water run back and let air to pump.   Originally, I built some king of silencer here, but it took a lot of volume and really did not silenced ait flow too much.  So, silencer removed and replaced with Y duct now.  Second thing why I gigged here was the  problem with electrically controlled valves. I thought one of them just broken, but it appeared the issue in connecting them in parallel. DO not connect these valves in parallel, otherwise they back feed each other and never stop. Decoupling diodes must be installed on the ground lines...
