    Need A Metallurgist's Advice

    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...

    Fish finder/bottom map

    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 FWIW…..using fixed frequency (200 kHz) “conventional” sonar is obsolete, old school technology.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...

    Fish finder/bottom map

    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.

    Need A Metallurgist's Advice

    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...

    J115PLSOR cylinder bank temp difference

    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...

    what are low hours on a mercury 150

    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...

    GPS Speedo

    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

    GPS Speedo

    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.

    Electrical short

    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...

    West Marine files for Chapter 11 bankruptcy

    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

    Fish finder/bottom map

    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

    Left side lean?

    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...

    Towing Coverage Progressive or Boat US

    I’ve had both. Unless Progressive has changed their policy, they only pay/cover the first $500. My last tow was estimated by the towing company @ $1,500 Had the towing company tow me to small, residential ramp for $430. Called a taxi to take me back to the launch ramp to get the trailer...

    Fuel system issues

    Make sure your vent line is clear. Seen water accumulated at the “dip” in the line a number of times. A bit of compressed air clears it

    How to tighten up rack/pinion slack in steering

    All connections tight? Mine NFB helm was getting loose to the point I was researching new helms. Crawled under the helm to get a part number off the unit. Found both steering cable nuts loose. Quarter turn on each nut snugged them right up. To answer your question, I’ve had roughly 1/2” of play...
