    In dash GPS speedo?

    I’m in the measurement business. You would be amazed at how many customers (experts) spend big money for instrumentation with far better performance than needed to met their need with little to no ROI In that line of thinking…given the wide range of recommend WOT rpm and that most props are...

    In dash GPS speedo?

    This is one of those things you hear repeated that makes absolutely no sense in practical terms I’m anchored in a 3 kt. current. My paddle wheel (water speed) says I’m doing 3 kts per hour. My GPS says I’m not moving. Which is right? Traveling the 96 nautical miles from Chesapeake Beach to...

    Trailer repair installed wrong disc actuator on 2 axle drum trailer

    Agree. Response would be slower (milliseconds). Pressure would not change. The master cylinders are the same with the exception of the size of the hole in the “check valve” and the disc cylinder would have a 1/8" NPT hole for the backup solenoid. Back in the days before they marketed both...

    Trailer repair installed wrong disc actuator on 2 axle drum trailer

    Think about it…if the brakes wouldn’t work w/o the check valve, how does a backing solenoid work? In effect your dumping the “residual” pressure back to the supply. https://trailerparts.com/ufp-reverse-flow-brake-actuator-solenoid-3-8-thread.html

    Trailer repair installed wrong disc actuator on 2 axle drum trailer

    You can not use a drum brake actuator on disc brakes (unless you drill out the fluid port) but you can use a disc brake actuator on drum brakes. I think your over estimating your weight by a good bit. Dry weight is #5,248 with a load capacity of #1,600 for a total of #6,848. If your boat...

    Trailer repair installed wrong disc actuator on 2 axle drum trailer

    No problem using a disc brake actuator on drum brakes. Cant use disc on drum. From what I’m seeing the Dexter A60 looks to be #7500. How much does you boat and trailer weigh? https://www.etrailer.com/Brake-Actuator/Dexter-Axle/DX56FR.html

    Need a new Battery for 24V System

    You need deep cycle batteries to run trolling motors. The higher CCA and RH numbers point to a marine starting battery. The number that matters is the AH (amp hour) rating While your at it I would have the other battery load tested. The SRM 27 is a pretty robust battery. I would be concerns the...

    Access to gas tank

    They are typically in the middle of the cockpit floor under a deck plate. Unfortunately, a lot of mfg. don’t provide access and you have to make your own.

    Pairing engine size with boat size

    The transom strength has absolutely nothing to do with a boat’s HP rating. https://towers4boats.com/maximum-boat-horsepower-calculator/

    Regular fuel

    Assume your using E0? Adding more alcohol (Heet) to E10 makes no sense

    Pairing engine size with boat size

    Here is the basic math…your boat takes X HP to move at a given rate of speed. It takes roughly 2,500 Btu to generate 1hp. This does not change if you go with a 75 or 115 hp motor. What does change efficiency is the combustion technology. The difference between a carbureted two stoke and an...

    Distorted Fish Shape On Fishfinder?

    F Distortion….bottom shows mirror image below it. Doesn’t take much movement to distort the image. One of the reasons I don’t use down view. Much better target detail using conventional CHRIP sonar. The time (GMT) is set off the GPS satellite. You only have control over the offset (local time...

    smartcraft tach lcd

    Viewing displays in an open boat (sunlight) is always an issue. Back lighting, special anti glare screen coatings, etc. improve visibility but don’t resolve it. I suspect the SC displays are not designed with full sunlight viewing in mind

    Kenwood radio interference issue

    What motor are we talking about? You say “interference”….how does it manifest? What happens if you remove the wire running between the two units. Head unit functions normally? No static? How does starting the motor affect the voltage to the units? Where are you pulling power from? Both units...

    2 sonars off the same transducer

    Assuming both units would support the same transducer, (power and frequency) you would need a way to switch the cable from one unit to the other, I.e. selector switch. Assuming both units support a NMEA 2000 interface, you could network the two units together and “share” the transducer signal
