    What are the 2 sensor on the thermostat housing?

    The buzzer has 12v switched power to it. Grounding the wire (or closing the switch on the sensor) completes the circuit. I assume you did theses tests with the ignition on... For the gauge, make sure you're getting 12v to the gauge (purple), and then trace 12v along the sender wire to the sender.

    2002 Mastercraft 5.7 harmonic balancer moving in and out

    I feel like at 3500 rpm under load this wouldn't be a long term solution

    Can someone explain to me how the hell this would run without your camshaft turning? Certainly can't run for very long...

    4.3 TKS "Run On" fixed but Slight Loss in Performance

    Came here to say that. Iridium plugs in these engines would only be for maintenance/longevity. Nothing in my boat lasts long before being changed for one reason or another, or "while I'm in there". So copper is fine for me.

    4.3 TKS "Run On" fixed but Slight Loss in Performance

    If running a hotter stat and plugs gave you the equivalent of 50 hp, I'd be the first one in line at the parts counter. Switch plugs back first, see if it changes, switch T-stat next, see if it changes...

    Visible exhaust after starting

    Open a bit from the start. Or if it's starting fine, leave it.

    2016 Mercruiser 6.2 ECT - long beep every few minutes???

    Or disconnect both ends and put an ohm meter lead on each end... Nah, that's a win. Maybe even bonus points when a problem fixes itself.

    Aristocraft 19 Question

    Keep in mind that your 1968 power train is just as obsolete as anything omc branded. Unless you're experienced with *marine* mechanics, and have had boats before, this probably isn't a great first boat. Your picture looks like a bigfoot sighting btw, impossible to tell anything from it.

    Replacement Fuel Sender?

    Exactly. Gauge doesn't even flutter. I'd be happy with a base 3 readout...

    Cobra sx outdrive

    If it's the Y-pipe you'll get water in the boat when running on muffs. If it's the transom seal/bellows/trim wire it will only leak in the water.

    Replacement Fuel Sender?

    The problem is that even at 1/2 tank, the area where the sender is located (aft section of the tank) is completely full. The tank empties as much fore-->aft as it does top-->bottom, since it's always angled towards the stern.

    Replacement Fuel Sender?

    Trying to get a somewhat accurate fuel gauge reading (like to within 1/4 tank would be great). I replaced it years ago and for some reason shortened the arm. I installed a heavier motor and cleaned up the helm connections. The heavier motor especially now shifts the gas to the stern, and the...

    Boat swamped, let's see if we can get it running...

    OK, got my fancy pants timing light today. Much easier to set digital than the tiny knob on the other one. Set to 8', verified 23' advance at 2500 rpm. It was bouncing though; not sure if this is normal? A couple of degrees in either direction, only at speed. Steady at idle. Thought it might be...

    No I didn't. Didn't plan on pulling them...They're on their second season. But good thought.

    Perfectly for 15 minutes then, surging, knocking, and jumping tac

    You can swap wires and see if the problem follows the wire. Carb rebuild is pretty easy. Even if you've never done it, shouldn't take more than a couple of hours.

    Don't think op disconnected the tach

    Perfectly for 15 minutes then, surging, knocking, and jumping tac

    Like I said, agree that the immediate issue isn't the flashes (though it may mean the engine isn't performing as well as it could). But how do you explain the tach?
