I wouldn't trust that at all. An under voltage condition will cause miss-fires. Put a good voltmeter on the battery terminals with the boat running. . Should get close to 14 volts while running. 12.7V with the boat runnng Yes…. The problem with using ohms to determine the condition of a coil...

Not getting up to speed sounds like a dropped cylinder. The tach bouncing around sounds like your losing a voltage regulator. Have you checked the voltage while running? Have yet to have a bad coil not pass the ohms test. I replace at the first signs of any cracks in the case as PM

Guessing you worked with 6061-T6 since 5052 is not heat treatable. The 5052 equivalent would 5052-H32

Nothing to do with “old” technology, it’s marketing. They “dumb down” and/or package recreational units to hit price points. Commercial units buy you a better build quality and the ability mix and match components to suit specific applications. Bear in mind that the real magic is in...

Did some work on bronze and aluminum casting designs back in the day. Welcome to my world.....lol At 2:23 one of our measurement devices is front and center on the screen when they give us a shout out......"characterized by close thickness tolerances"...lol

Good AI answer….lol Guess AI hasn't been in the metals industry as long as I have..,,,,lol Pure aluminum is smelted with other elements to create the alloy. The finished material is then poured into billets or slab depending on the end product. Material destined for sheet products is in slab...

Pretty limited selection of transducers for that unit. Not seeing a true CHIRP or high-wide offering for your unit. Looks like what you have/ordered is your best bet. FWIW…..using fixed frequency (200 kHz) “conventional” sonar is obsolete, old school technology. Surprised Lowrance is even...

I see Lowrance is still playing games with their CHIRP nomenclature….lol What kind of fishing are you doing? If freshwater, 455/800 kHz would not be my choice.

Most aluminum alloys are not readily bendable with heat or no heat due to its crystalline structure. Since it’s bent, we know that it’s a 5XXX series aluminum which is highly mailable, ie readily bendable w/o heat Aluminum is cold worked since heating aluminum is detrimental to corrosion...

Unlike a pressurized automotive cooling systems which share a common heat sink/source, the temps on open loop cooling system are not homogeneous. The intake side of the loop is always going to be cooler than the exhaust. The colder the intake the higher the temp differential between intake and...

Are you looking for cylinder compression or the compression ratio? Stated compression ratio is somewhere @10:1

The "average life expectancy" isn't a reliable measure of longevity. Marine motors that die a natural death are very few and far between. They almost always die of abuse and neglect. The problem I have with an "average life expectancy" is that maintenance is not taken into consideration. A...

They are plugin accessaries on a lot of mid to upper tier plotters and sounders. I use mine for tidal compensation while trolling https://pdf.nauticexpo.com/viewerCatalog/airmar/st61-transom-mount/22646-125761.html#open381425

Agree...my boat didn't even come with a speedometer. My boat has three speeds.... 1,000 rpm ("no wake"), 4,400 rpm cruise (~31 MPH) and 850-950 rpm (trolling speed) Having said that, I have both GPS (x2) and paddle wheel speed inputs.

These types of failures are typically badly compromised battery cables or motor windings (pumps) shorting to ground If it were me, I’d find a way to remove live well pump completely from the circuit before tearing into it any further. You start checking components at the battery and work your...

Locally, we used to have one every third intersection. Been dropping like flies for the past 5-10 years. Only know of a couple within a 50 mile radius anymore

I want nothing to do with a touchscreen on a boat. Besides blood and guts all over the screen, trying to “touch” the correct entry in a pull down menu or hit the correct, tiny button while doing the Chesapeake waltz just suxs. Don’t use touchscreens in the car either. Prefer dial/trackball setup

No old equal and opposite reaction at work;) The clockwise rotation of the prop forces the boat to lean left. They all do it. Manual trims tabs will resolve the issue

No, they are not the same. Garmin owns Navionics, but markets charts under their Garmin Navionics, Bluechart, LakeVu and Vision brands Lowrance Supports C-map and Navionics charts. Humminbird supports LakeMaster/CoastMaster (propriatray) and Navionics charts. Garmin units typically comes...

I'm fortunate in that I don't live anywhere near any of "them parts" of the country.
