Columbia 10.7 Rehab log entry #8 mechanical systems

I went through the mechanical systems in the boat and updated and replaced items.
The first was the water pump and lines to the various faucets.

Water System
The water system in the boat was a typical set up with a 40 gallon tank for the fresh eater feeding into a pressurized pump which is turned on at the main breaker panel. It fed the head sink and shower, the galley sink and the hot water heater. There was no outside shower on the boat.

Upon inspection of the water system, I found that the electrical lines had been cut to the 12 volt water pump that was mounted by the hot water heater tank in the cockpit of the boat under a seat. I hooked up a battery to the pump only to find it had no suction.  I replaced it with a Flowmaster pump that could handle the flow needed for the boat. I decided to move the pump into the cabin and place it under the port settee near the fresh water tank. This required less travel distance to the faucets meaning less lines to worry about.
I ran fresh wires from the main fuse panel to the water pump and hooked it up. The cold water runs great to the faucets int he head and the galley.

Hot water heater
The hot water heater which was electric 110 volt was missing. The only evidence I saw were the wires remaining under the seat in the cockpit. I purchased a tankless hot water heater that runs off of propane. I mounted the unit in the cockpit under the port seat so it has plenty of air flow and ventilation. It works great. On demand hot water. It only kicks on when the hot water nozzle is opened.

Air conditioner
I was pleasantly surprised to discover that the aftermarket marine air conditioner on the boat worked well. The controls are analog so no digital panel as of now. That can be replaced and upgraded by the next owner. I didn't want to mess with it as it works great. 
I did replace the hoses coming in from the raw water and the circulating hoses and clamp. I dismantled the raw water strainer and cleared out the debris. the separate high end raw water pump now throws a ton of water through the unit and out the through hull fitting, thus keeping the compressor cool and cranking out a lot of cold air.

Bilge Pump

As with many other systems, I am baffled by the previous owner cutting the wires for the bilge pump.. I did find the bilge pump mounted int he center of the bilge under the sole of the boat. It didn't work though. i replaced it with a high end, high output pump which I rewired into the main fuse panel. It now discharges a huge amount of water in seconds from the bilge.

Refrigeration
The boat has an ice box style refer that you place ice in and has a teak grates . It is totally mechanical and uses no form of power. I am placing a small 110 volt refer into the boat  where the chart table was removed. if there is room, I will replace the chart table over the refer.

Propane system
There is a single propane tank in its own hatch in the cockpit. It has a line that runs to the galley. I had new hoses made to connect the new tankless hot water heater and the stove/ oven. New tank of propane in the well. I then tested the connections for leaks and it was good to go.

12 volt electrical system
The 12 volt system is in tact and working well. I am replacing several of the 12 volt lights int he cabin with new lighting. Each of the 12 volt switches / breakers on the main panel work well.

110 volt electrical systemThere is a 30 amp shore power receptacle on the boat in the cockpit. The 110 system was plugged in and works well. The boat is equipped with a Rareitan Crown 2 marine converter system that also has a battery charger installed.  The converter wasn't working when I first checked it but I found that one of the 7 amp fuses was fried so I am replacing it and will fire the converter up and attach the battery charger.

Ray Marine 4400 SL Auto Pilot

The boat is equipped with a Ray Marine brand autohelm. The previous owner decided to rip out the wires from the $500 Fluxgate compass. No worries, I found a new one on Ebay for $50 and bought it . I will be installing it soon.  Also the belt that turns the ships wheel was destroyed so i also ordered a new one for install this week.  I need to track down the 12 volt power source for the actual head unit with the screen. I will get that working and we will have a functioning $3000 totally rehabbed outopilot... Comes in very handy when you need to go down below and mix another Captain Morgan and diet !!

Columbia 10.7 Rehab Log entry #7 Engine tweek

So... I mentioned in the transport log entry that when I was delivering the boat on the maiden voyage, the ignition switch caught fire... I didnt know the extent of the damage but I was confident that it didn't affect the engine at all.  It didnt damage any of the fiberglass or the boat in general. Just melted the plastic guage cluster.

 Turns out that the ignition switch that was previously installed had been a cheap switch. The contacts corroded, got hot and caused the fire.

I had the oil and temperature guages replaced and mounted under the cabin bulkhead so I have a good look at them while underway. I finished refitting the actual panel that you see above so that it only houses the new ignition switch and the glow plug toggle. ( See photos)

  

I hired a well seasoned Marine Diesel mechanic to go through the engine and electrical system and fix anything that wasn't right. He has done a great job so far. The following work has been done.

1) replaced the corroded ignition switch with a mac daddy marine ignition switch.

2) replaced the thermostat to keep the engine running cool.

3) replaced the 2 batteries in the boat with brand new 750 cranking amp deep cycle marine batteries.

4) replaced the alternator with a new OEM model. The old one was bad.

5) checked all fluids and topped off.

6) replaced several wires that were showing wear and age to ensure the best possible performance and dependability.

7) replaced all the guages to new and replaced all the wires as well.

8) installed new switch for the glow plugs.

9) Installed 4 new glow plugs

10) installed new starter.

11) installed new battery isolator switch.

The boat boasts a nice Westerbeke marine 4 cylinder diesel that runs strong and starts with ease. it only has 1400 hours on it so its got a long long life ahead of it. The total spent on the engine to make it perfect was $2200.00
