Found and replaced some missing nuts and washers this morning on the engine. One set on one of the engine mounts had “rattled” off apparently, down inside the pan. Had to hunt with a flashlight and reach into the deep, dark recesses beneath the engine to retrieve them.
Had purchased a couple of sets of spares yesterday, and wound up using one of the new nuts. Found the other, can’t reach it at the moment, my arms don’t fit down there.
Tested the transmission levels today, started engine, brought her up to operating temperature, put the engine in gear and stressed it forward and backward… pushing water very well.
Shut down engine, and tested levels, and they are right.
I believe I’m losing transmission fluid through the oil cooler assembly at higher operating temperatures under pressure. It’s not a LOT at a shot, but it’s enough that after many hours, I need to add fluid.
I think I will end up having to replace the cooler (a double cooler set up).
Hopefully, we’re going to get our provisions together in a couple of days, take care of some things in the area like our storage locker, and a tire giving me fits, and then do a test run of the engine.
Might just come back, drop our temporary crew member off at the docks and kick off and keep going if we have everything ready for the trip by the time the weather is good enough to do an engine test run.
Just ran the water maker. Last time was a nearly empty tank (a couple gallons left in it) on 28 September 2019. Filled the tank in about 5 minutes under three hours.
Today, we started the maker at 1350 hours local. The machine ran for 1 hour and 40 minutes and the tank “popped”, letting us know water was full. The tank makes a noise when it is full, I assume one of the sides bulging out slightly. JoAnne also observed noise at the air pressure relief behind her seat, and the over flow began flowing into the bilge.
So… 21gal/hr * 1.66666 hours = 34.99986 gallons of water
It took us 9 days to use 35 gallons of water from our tanks. That’s pretty average for us, when not taking showers on board (which is extremely rare for us to do). The calculation is for the amount of water produced per hour (nominal 21gph) and the time is the number of hours in decimal format for how long it actually took to fill the tank. So, 1 hour, 40 minutes is roughly 1.66666 hours. Multiplying those numbers gives me the quantity of water produced over the time period.
(At some point, I’ll calculate the exact amounts of water, gasoline, wattage used and probably soup up the solar panels a bit along with the generator! Actually, the solar isn’t used for the process, but, I like being able to keep the batteries charged using them, and I know the DC side uses almost 10 amps. So, that was almost 20 Amp hours!)
High pressure side ran at just under 700 psi
Low pressure side at 8 psi, and went up to 20 psi as the process continued.
A check of the filters shows they need to be pulled out and cleaned. I’ll use those a couple more times (after I clean them tomorrow and do a system flush with fresh water) and then when we arrive in clear water, I’ll swap the filters out for new ones. Not sure how long they can be used for before you are supposed to change them.
We did keep popping a breaker for the lift pump for some reason. But after I started up the high pressure pump it stopped. I assume the lift motor was working a bit too hard.
Today I ran the engine, mentioned above, and used the bow thrusters to check them, pushed bow out a bit. Noticed that the battery charger has kicked in, I assume due to the use of the thrusters. Also, as a result of the low pressure pump doing it’s thing. It draws about 10 amps while running.
The fridge draws five pretty constantly.
We also run several DC fans on warm days like today, so the power draw adds up. The system is currently charging at about 80% and it’s not “ready” yet, like normal.
I did check the batteries a couple of days ago, added water to them, and checked a few random cells for charge (they were good).
I also have replaced a double pole, double throw toggle on the battery meter, which I thought was broken, showing low readings on the meter. When I tested the output on my digital meter, it read normal (at 13.5vdc) so I assumed the wires or switch bad. Replaced several connectors, cleaned some connections and replaced the switch and things were fine.
Last night, I noted the meter was reading low again, and yet with a digitial meter, it was reading fine.
Checking things a few minutes ago, I noted the power system is charging, and the meter reading is normal, showing a charge on-going. The secondary (old) Xantrex meter still in the circuit is also showing 13.70 vdc, which means the system is charging.
Not sure yet if we have a flaky connection back in the battery bay or what yet. I’ll find it eventually though.
I’ll double check the voltages on the batteries, and probably test all the cells before we decide to do a shake down next week. Shake down will likely be next weekend or just before or after the weekend (to avoid the fishing vessels and the guys who don’t know how to drive their boats).
