    Voltage Regulator Problem

    Your motor does not use any battery power for the ignition. It only uses battery power for the starter and any accessories, gauges trim, etc. So as long as the motor is running, it will run until the fuel runs out. VRs can go bad. See if you can see any burn marks on the circuit board. A...

    Warm up

    Those motor do not need that much time to warm up. Does she bog down, when you try to accelerate, but run OK at idle in gear?

    Tach for Merc outboard

    There certainly are resistance specs for stator coils. I do not know what they are for your stator. As long as it is not open or shorted, it is probably good. On some of those manual start motors, the stator is really a lighting coil. Expected to run some lights only. I am not sure how that...

    Older Merc 150 2 stroke really rough below 3000 RPM

    When he says "ethanol damaged" carbs, I hope he means dirty carbs. When you first run gasoline + ethanol, it cleans the fuel system and this loosened dirt can get into the carbs if the filters are missing or damaged. After the first use of gas + ethanol, it has no effect on the carbs...

    Carpet glue

    usually 1/2 plywood is all you need. I would recommend you seal all the plywood surfaces with spar urethane or at least marine varnish. Polyester resin is better than both of those, but you may not have it around.

    Humming/ Buzzing in dash

    Not sure what you want. Either the gauge is set to alarm at 2 feet, or the electronics are bad. The first test is to turn off the alarm off. The OEM web 'site may have a manual. If that doesn't work, and the gauge works correctly otherwise, kill the buzzer and see how it goes.

    high idle

    If the thermo valve is not closing after warm up, or the vacuum hose to it is leaking, the idle RPM would be high.

    Older Merc 150 2 stroke really rough below 3000 RPM

    It sounds like you are on the right track. The carb model of that year looks to have std carbs on it. Each carb will have a idle mixture screw for each barrel. There should be carb kits both OEM and after market on the web.

    Mercury 150 xl 2 stroke, carbureted, head temperatures vary by 15 to 25 degrees

    Gee, what is the issue?

    high idle

    Some of those motors have a thermo valve, which allows extra air to raise revs. You might see if it is working. Trace some vacuum lines to the head.

    6300 RPM is a bit high for a production engine.

    184 MA draw on main battery cable

    Those Mercruiser PTT systems have a trim limit switch. They are open to the water, and therefore rot out. So repair the switch, if even possible, get used to using the trailer button to trim up, or wire the trailer button to the trim up switch...your choice.

    Humming/ Buzzing in dash

    Sounds like a shallow water alarm. See if you can reset the low water alarm threshold, or turn it off.

    184 MA draw on main battery cable

    Some Mercruisers have repressed current systems to protect against galvanic corrosion. These use some small current when boat is moored.

    1150 Link & Sync Question

    OK, well for that size boat, that 2.5MGP seems pretty good. The flatter bottom helps with efficiency. Make sure the tilt pin is on the lowest setting. With a tach and a GPS you can maximize the efficiency. I would expect the whale tail to rob you of speed and efficiency, as it adds drag. If...
