    Depth sounder offset. True or depth beneath keel????

    I find this thread quite entertaining. First of all, depth on a chart is the normal low water. Any depth on a chart that is in a tidal area, is going to fluctuate based on tidal stage. So it's unlikely that your depth will match the chart depth. Secondly, in a shallow area where you are...

    fridge "dripping tray" frozen

    When mine enters the defrost phase, you can hear a very slight clicking. My guess is that that noise is the time clock running the defrost cycle. When it switches out of the defrost phase, the compressor starts and the compressor noise is louder than the time clock. On my refrigerator, the time...

    fridge "dripping tray" frozen

    Check the door seals and that the unitis defrosing. Typically refrigerators have low humidity inside as the moisture coalesces on the evaporator coil. Then when it goes through the defrost cycle, the frost melts and drains through the tube. If the door isn't sealing, there is air exchange with...

    Cleaning Racor filters

    The bowl is replaceable as a separate item. If you go online and search "Racor and the model number", you will find a schematic for each model with the associated part numbers. Then Google Racor and the part number. In addition to the bowl, I would get the seal to the housing and the seal to the...

    Oil analysis shows coolant in oil Cummins 6BT

    While an oil cooler could explain antifreeze in the oil, I wouldn't expect it to indicate high sodium as the oil cooler is in the antifreeze loop, not the raw water loop. Were the oil and antifreeze levels normal, higher or lower? On a 6BT, there's no place where the raw water is separated by...

    Bow washdown fitting replacement

    It looks to me as though the bulkhead fitting has a tube like a hose barb, with a swaged ring, acting as a clamp to hold the hose on. Don't know if you can cut the blueish green ring off with a Dremel tool, replace the hose, and secure it with a hose clamp. Ted

    Depth sounder offset. True or depth beneath keel????

    I have 3 transducers in Slow Hand. 2 are set to depth under the keel and one is depth of the water. Depth of the water is for communicating with other boats. I think in depth under the keel, clearance. One of my best ideas was to mount one of my transducers as far forward as possible, maybe 8'...

    Ignition key run position positive wire

    Then what stops the engine? Do you press a button to stop the engine or turn off the key? If the engine is electronic, you're turning off the computer. If mechanical, you are generally switching a fuel solenoid on or near the injector pump. Ted

    Sad! Hard to believe you don't have a preference for one over the other. Ted

    Ignition key run position positive wire

    Most diesels have a fuel shutoff solenoid which is usually wired power on with the ignition switch on. I would determine amp draw of the charger power switch before assuming the circuit will handle the load Ted

    Why a secondary fuel filter?

    It's extremely unlikely that your secondary filter is greater than 2 microns. A simple question: When the primary lift pump fails and debris goes down stream, do you want to have to rebuild the injection pump also? I can't think of a diesel engine manufacturer that doesn't have the smallest...

    Dometic VacuFlush head, my first dive into troubleshooting

    Hope you turned the pump off. If the bowl seal is leaking, open the bowl valve all the way and wipe the inside of the seal with a wet rag to make sure it's clean. It's also important to not let the valve close slowly. From wide open, simply remove your foot from the pedal and let it snap shut...

    Flies

    I bought a 12" sticky tube from Walmart that had caps on each end. They're in the camping section. Basically like fly paper that you hang, only smaller. My saloon table had a 5 gallon bucket under one end for trash. I mounted the tube over it. What was interesting to note was that flies were...

    Repair westerbeke or replace and with what?

    If the generator has 960 total hours, I would find a professional generator technician. Twice I thought my buddy's generator end had died from to much full load use. Each time the technician came out and diagnosed the problem with a low cost repair. From recollection he lost a capacitor one time...

    Grand Banks 36 single screw

    Generally there is a cutlass bearing at the propeller end of tube or bearing holder. Usually there isn't one at the transmission end as either the transmission or shaft seal act as the bearing. Usually a cutlass bearing in the center of the tube means the rear cutlass bearing moved up the tube...

    electrical connector question

    Depends on the amperage of the pump. Ted

    Why did voltage drop?

    Yes, the charger appears to be switching from "standby" to charging. On Show Hand with the Siren Marine monitoring system you could see the charger go to standby and the voltage slowly decline over hours until it switches back to float for a few hours, and then the process repeated. In your...

    Heads up for the Rideau 2024 season

    In 2022, due to a rush our restriction or something like it, I went under the fixed bridge on the Causeway. My recollection was that I had more than 15' and over 6' of depth. I remember catching the bridge opening going the other way. Ted

    CASH???

    I recently sold my truck after 22 years of ownership. Collected $6,000 cash. I wasn't interested in anything other than cash or a bank check, and he didn't want to add the expense of a bank check. Depending on how much you're planning on spending, I think it’s unlikely to happen going through...

    50A 125/250V 6/3 shorepower cable for use with 50A/250V isolation transformer

    Ebay. You want S/O cable. There are companies that buy 1,000' spools for manufacturing products and sell their spool ends on eBay. I bought 45' to make a 50 amp 250 volt dock cord. S/O cable doesn't have quite as thick an outer jacket and is usually only available in black. Ted

    The Case for Going Slow

    That was the case with Slow Hand my Cherubini Independence 45. Replacing the single engine from 450 HP to 132 HP about cut the fuel consumption in half. Doing much of the work myself and selling the original motor at a good price kept the cost to about $10K. Probably saved 9,000 gallons ($35K to...

    The Case for Going Slow

    Most MFDs will have an odometer built into one of the sub menus. Many also have a trip odometer as well. As they use miles over the bottom based on GPS tracking, they are quite accurate. I zeroed the the odometer when I started cruising and the trip odometer each year. For me, average...

    Stop Anchor

    On Slow Hand with its all chain rode, unclip the safety and loosen the clutch. Probably takes 15 seconds to dump the first 50' and 10 seconds to dump the next 50'. Then tighten the clutch and hit the bow thruster. Ted

    12 Volt Socket

    I believe that's an incandescent bulb and cord socket. On my charter boat I had an anchor light bulb that was 50 watts and they made them up to 100 watts. At 12 volts, that would be 8+ amps. The contacts on the bottom of the bulb were long soldered strips that would mate with that socket. The...
