    After 20 years of lake boating, tried something completely different

    Fish out of Ocean City, Md. and Virginia Beach, Va. on a regular basis. Going back in after dark from a day offshore (40-90 miles out) never gets old. You go from total darkness to just a shimmer of light on the horizon that slowly builds to a city of lights over time. Fished for marlin out...

    67 Year Old Head Bolts

    Penetrating oil and a 1/2” pneumatic impact gun is my go to. Turn air pressure down a bit to loosen up any crud in the threads before going full force. If that doesn’t loosen them, I use two ball peen hammers to break it loose. Place the small end of one hammer on the head of the bolt and...

    Identify the thread of this screw from my boat

    In machine world, a tolerance is assigned to the dimension based upon the presentation of the number. See below In the case of a 10-24 UNC screw, the “basic” major diameter is 0.190” however, the actual diameter can vary from 0.1890” to 0.1818” diameter. Had this been a 10-32 INF, the basic...

    Been a little cold.

    But, But, But....outboards are self draining even with the foot tilted up......lol Outboards have an open loop cooling system. The only thing keeping the block from draining is not storing the motor verticaly, possibly a plugged thermostat and/or a loss of gravity. Have left the foot in the...

    daily music fix

    Skipped 8 track and went straight to cassette when I bought my car in “73”. Dad had a recording studio in the basement. Had a couple of TEAC, 4 channel reel to reel recorders. Bought a Nakamichi cassette deck to transition to cassette. Spent many late night hours recording “under...

    Mobile home internet

    We’ve had 100/100 Fios since 2012. A couple of months ago they offered to increase our speed to 500/500 while dropping the price $10 a month. Didn’t make sense. Turns out, they changed the contract language. Instead of guaranteeing 100/100 minimum, the 500 service was “up to” with no...

    Mobile home internet

    Guess it depends on the bandwidth in the area. Since VZW switched over to 5G messaging, messages can take up to 30 minutes to processed and passed along in our local area. Have not noticed much difference out of our area.

    Not a fan of the lanyard type devices. Lost another this winter fishing solo. Cant fish tethered to the helm. An unintended shutdown at the wrong time can could pit you in peril. Wireless kills are much more user friendly

    Prop Walk, need a possible solution.

    Maxed the boat out going from 115HP to 150HP on a 17' boat. A little squirrelly, but not bad at all. The issue he had, and why he asked me to test drive it for him was that it took Popeye to steer the boat to port . He ended up getting a lawyer to make them put the proper 25" shaft outboard...
