    Boat reverse polarity

    Reverse polarity in a AC circuit is a grounding issue. Swapping the wires of an AC supply makes no difference to the load. Has their been any electrical work done on the supply line? The most common cause is reversing the neutral (blk) and hot (wht) wires on a receptacle or plug. White or red...

    1998 evinrude 225 ocean pro help #2!

    What is the temp of the water? If the water is too cold, it can take a minute for the water to come up to temp and open the stats. Having said that, I can't say if that's typical behavior or not when running the motor out of the water. The motor is designed to run off the flushing port. I've...

    Plugged into what? This is a supply side issue, not a boat problem

    New boat owners leaving the hobby

    Quite a change from 10-15 years ago when there were waiting lists and huge backups at the ramps on opening day of Trophy Striper season. Since they closed trophy season and moved the opening day of Striper season back a month (fish are gone), most like myself can’t see spending $$$ in fuel...

    Boat reverse polarity

    Guessing this is your AC panel since hooking up the batteries backwards would have “smoked” any electronics onboard. Either your power cord or power reciprocal has neutral and ground switched

    Humminbird issues

    Certainly not the case anymore. From a hardware perspective, you get what you pay for. There is a huge difference in quality and design between entry level (big box) and professional quality hardware on the market The money, like most things these days is in the software. Technology advances...

    Do I need a trailer?

    Depends on the weight of the boat. I hulled a 12' Montgomery Ward Sea King aluminum boat with a Johnson 5 hp around in the back of a pickup with a 8' bed for years. No problem getting the #120 hull in and out of the truck by myself.

    Humminbird issues

    The computer is failing to initiate/boot. Make sure all software updates are done. Could be waiting for a response from a peripheral, communicate link, map chip, etc. Unplug all peripherals (transducer, link, gps module, etc.) and try again. If that doesn’t work you’ll need to have it...

    2007 3.3l 250hp starting at 3000+ rpm

    Wild ass guess not knowing the acceptable range parameters of said sensors…..the voltage on your accelerator position sensors are 0.024 volt apart. The throttle position sensors are almost 2.0 volts apart

    Merc 377 MAG DTS AXIUS electrical issue

    The only way to get 8.5 volts from a 12.5 source is by resistance or excess current draw. Current flows from positive to ground. A bad connection/wire (increased resistance) can be on the supply or ground side of the circuit. To troubleshoot this properly, you need to dig into the schematics...

    M40C Tachometer install weird readings

    Scratching my head as well….. Makes no sense unless he’s picking up some kind of induction “fly back” off the coil. I use a similar unit to adjust carbs on 2 cylinder, both 2 and 4 stroke, motors w/o issues.

    M40C Tachometer install weird readings

    Looking though the manual, the unit is rated up to 16,000 rpm at 1 pulse per revolution which is 266.6 Hz If your getting 4 pulses per rev as it sounds, your exceeding the 266.6 Hz read rate of the unit at 4,000 rpm, thus the error noted at higher rpm

    Deck to Hull Seal needs replacing

    Guessing the actual seal is under the rib rail. Looks like someone took a short cut and applied RTV to the underside of the rail instead of removing the rib rail and doing it properly.

    Voltage between batteries and aluminum hull

    For future reference, you could have quickly eliminated the electrical harness as the source of the problem. Remove the ground cable from battery then check for continuity between the cable and the hull. No continuity, no ground leak.
