Day 193, Engine, finishing heat exchanger installation.

-

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 to send to SignalK:

  • Engine head coolant temperature (Coolant out)
  • Return coolant temperature (Coolant in)
  • Raw water temperature after heat exchager
  • Wet exhaust temperature 
  • Transmission temperature
  • Packing temperature 
  • Engine compartment air temperature.
  • Oil pressure alarm
  • Coolant overheat alarm
  • Alternator voltage
  • Start battery voltage

Later plan to connect 

  • engine oil presure
  • Fuel tank level
  • Coolant level alarm
  • Oil level alarm (likely will skip it) 
  • Water in fuel filter sensor 

Custom made board mounted in ip67 box inside the engine compartment. 

Software is based on SensESP project. ( installation is in progress)

Pedestal.

Pulled wiring from pedestal, cleaned and redone all connections with heatshrink butt connectors (with glue).

Tachometer and hours counter installed on the side of the pedestal.



Interior
Try to fit cabin table. for some reason it appeared for me today so massive  and taking so much space... 
Maybe cabin is too crowded with tools and parts.Or maybe I just do not want table.

Day 183 1/5/25 Take engine home.

Engine Take engine from the boat and move to home garage. Easy to say, hard to do. Water level in the lake now is 40ft below normal level. And total height drop between parking lot and docks about 70-80ft.  Marina has no lift, ramp or crane to move something more than 200 lb up way. Only way is very long stairs with 140 steps.   View form the parking lot...    Staircase we climbed up. Yes, you can see the lift, but it is only 200lb capacity and no way to use. Picture was made on the middle of the process. Based on engine spec it has to weight 400 lb. It is a lot but should be more or less bearable weight for 3-4 people. Challenge was accepted, but looks like it is heavy enough to do a problem ;-) Moving from boat to dock was very easy, just hook chain hoist to boom lift it  and swing boom to the dock. put on a dolly and roll it to staircase. After an hour of planning we (My son and I) decided to use blocks and ropes to slide it up. We mounted engine on the plywo...

Day 182 1/1/25 Engine haulout, added handle to refrigerator lid.

 Engine. Final decision made. I convinced myself to get engine out and repair engine mount stringers bonding to hull as well do check/repair engine "on side". Taking engine on my own was an interesting challenge. I am very pleased to boat designers for big engine compartment hatch! it was the game changer. Process to get engine out. Disconnect drive shaft coupler. Before disassembling I started engine put on gear and cleaned and slightly filed cylindrical surfaces on rotating coupler to have good reverence surface for alignment later.    There was no surprises but one bolt had not lock washer and bolts was not tighten well. Remove and starter, alternator  No surprises on alternator, but starter mount nuts are hard to reach due to starter body diameter does not give space to put 19mm socket on the nut (starter is to "fat") and I had to use 20mm socket sitting little "on side". Starter and alternator removed  Undo aft engine mounts.  Nuts on mounts are tight...
