    1962 evinrude needle valve assembly on carb

    I do not remember what my big twin had, but most needles have springs on them to keep 'em tight. You could also use teflon tape on the threads to add friction. Be careful not to let it get into the carb.

    Looking for guidance please

    Gee, I would suspect the ign is failing at it warms up. You might check spark quality, when she starts to sputter.

    1993 Astro bass boat 17 ft with a 93 115 hp Mercury 2 stroke. Over revving

    Match mark the prop housing and the hub. Dump her in the h2o and see if the marks move. One piece props are real hard to tell if they are spun. The modular prop hubs are easier to tell.

    Mystery vibration

    Hard turns can stress the u joints. Also, does the outdrive tough the transom mount in a hard turn? I get a little vibration when my OB is trimmed all the way down. it might be the same cause.

    The water drain holes I don't understand

    A lot of boats have bow thrusters built into that area. They are open to both sides of the boat, but sealed to the hull, otherwise.

    no reverse?

    Gee, why not repost this in the MerCruiser forum and tell them big block Ford/Mercruiser drive. Did you check the shift boot, if you have one? Corroded cable can restrict their movement, and the rest of the linkage can bend a bit to cover it.

    Polyester resin cracked while curing

    Sand it down and glass over it. The new resin should fill in any exposed cracks. I always fill over the cloth. Why did you fill first?

    Fuel gauge not working on Palm Beach

    Gee, there are 3 parts to a fuel gauge, Sender, gauge and wiring. The wiring is easy to check. The gauge requires ground, +12VDC and sender wires, that are clean, tight and supply the correct signals. First check: Grounding the sender post should make the gauge react. If it doesn't the...

    Ethanol Gas Observations

    Fiberglass tanks are not used with ethanol, because the alcohol is hard on FG. You see that in the JB weld failure. A green tinge on spark plugs is an indication of overheat. Same thing with the real clean spark plugs. Your carbs may be partially clogged leading to lean mixture. alcohol...

    2003 Johnson 150 port temp sensor

    If the diode was open, I do not think the alarm would "see" the ground signal. The diode is between the two overheat sensors plus the connection to the powerpack to signal SLOW, and the alarm sensor. The other alarms have their own signal wires.

    canopy

    Not sure what a canopy is. Bimini top? Navy top? Bimini tops can be pretty universal. Navy tops are more unique. Some marine stores carry premade navy tops and other canvass products for popular models.

    Trim tilt

    I doubt you need a new control. It sounds like some sort of wiring issue. What year and kind of motor?

    Gas tank issue

    If you can get to the gas gauge sender, and remove it, you will have a hole large enough to siphon out any liquid and insert a scope. Cleaning depends on what is in it.

    2003 Johnson 150 port temp sensor

    You might intentionally ground one of your overheat sensors and see if you get the overheat alarm. If no alarm, maybe the diode in the wiring harness is open?

    Recovering Boat Seats

    Yeah, that is why I use nylon coat thread, or polyester outdoor thread. They hold up for years. Carpet thread is another possibility, but not all machines can handle it.
