    2 stroke randomly does not want to start + house battery voltage seems low

    Mercs usually have preload on the throttle cable to help you find neutral. To do that, adjust the throttle cable at the engine, in neutral, to push the throttle closed a bit more to add the preload.

    Enrichner valve

    It could be a short in the enrichener coil, pulling down the voltage. I do not know if that circuit has a fuse. Pull the wire off the enrichener and test the voltage again. Also, perform a resistance test on the enrichener body to ground. Resistance should be zero. I have never had an...

    fuel problem

    When a 2 cycle outboard leaks fuel out of the exhaust, it can be caused by a leaking fuel pump diaphragm.

    1976 mercury 1150 115hp runs on muffs but not in lake

    You need to have +12VDC on the red and adjacent white wires to have spark. The red wire is "hot" all the time, and the white wire is powered by the ign switch. There is a test on CDI electronics web page that will test all of your ign components but the trigger. You need to pass that test...

    1976 mercury 1150 115hp runs on muffs but not in lake

    Triggers and distributor housings were $225 the last I looked some years ago. I think CDI Electronics made them, but Sierra is also a possibility.

    50 hp high speed misfire

    I doubt that is your issue, however, as was said, it is easy to check/clean. But, hey let's be optimistic.

    1976 mercury 1150 115hp runs on muffs but not in lake

    In your spare time, you might source a new trigger and distributor housing, for the day your trigger becomes intermittent. Just to see if they can still be gotten easily. At this time in it's life, (nearly 50 years old), they tend to start to fail.

    50 hp high speed misfire

    Those statements were of a general nature about ether. The fire extinguisher statement was for you though. The common dry chemical fire extinguishers are real corrosive, so if you need to discharge one, clean up the chemical promptly or it will corrode the carb, the throttle plates and most...

    50 hp high speed misfire

    Clymer and Seloc service manuals often have grossly inaccurate info in them. I would not use them, unless you are real familiar with the motor. BTW - whenever using ether, have a fire extinguisher nearby, as that stuff is real flammable. An engine may not have enough spark to run, but often...

    snapped driveshaft Mercury 2011 150 Optimax

    Fazt, I guess I am naive, but I do not think the driveshaft should be made so close to power output tolerance that it would ever snap. It is a big dumb piece of SS. Make it a bit stronger and eliminate that issue,

    Trophy 1703 motor choice

    Gee, why not run the Merc for a season and see how it goes. If you don't like it you can always switchover. 35HP is a lot to give up for snobbiness. The boat may wallow with the smaller motor.

    COIL INFO

    Gee, sounds like youneed a service manual. A parts place like crowleymarine will give you an idea if coil and wire are one piece.

    Gear case

    OK, see if SEI makes one. I know they make replacements for my '98 Johnny V6. Pay attention the the driveshaft length. My '98 has the 2 piece driveshaft, and the SEI replacement reuses the upper driveshaft.

    Battery charger size needed

    We don't even get ice here at the Jersey shore anymore. I do need to wear two sweatshirts when it is really cold....so at least I have that. In 20 years I won't need to winterize the boats. Mostly because I will be dead.

    Enrichner valve

    Put a voltmeter on the power wire to the enrichener, and see if you have +12VDC when the choke is pushed. If not => wiring issue. if so => enrichener solenoid is bad. You could also check the enrichener solenoid with an ohmmeter. I would expect a few ohms of resistance, if the solenoid is good.

    Gear case

    What brand, year and HP motor? SEI may make a brand new gearcase, for the price of replacing those gears, bearings and dog.

    how do i test tilt and trim motor on a volvo penta 4.3 gl sx with blue and green wires and no black earth thanks

    2 wire PTT motors use relays, not solenoids. Solenoids provide power when energized, and are open when not energized. Relays provide power when energized and provide ground, when not energized.

    Battery charger size needed

    Gee, this is like an oil debate. I like the slow chargers for boat batteries. Slow is best, as my pappy taught me. The motor charging system keeps 'em charged when I use the boat. When I am a slacker, and don't use the boat, I slap a 3A charge on it for 24 hours, or 48 hours for a dual...

    Water in the intake

    So freshwater cools the manifolds and raw water cools the risers? Is raw water salty? Probably the manifold is still good, if freshwater use. I would look at the risers, especially the joint between them. If any water goes past the gaskets on the manifold to riser joint, it can end up in...

    1976 mercury 1150 115hp runs on muffs but not in lake

    if you can find enough wire to connect to, I would recommend you remove the plastic insulation from a crimp type butt splice, coat the wires and splice with flux and crimp and solder the splice. Next some shrink tube over the splice.
