    1972 Evinrude 50hp selectric

    Green wire is for the Neutral Solenoid, and the Blue, is Reverse Solenoid, but both actually have to be energized to get Reverse Check for Continuity between each wire and Ground. You really need to get the proper Service Manual before you go ripping one of these apart. Yes, if someone has...

    Mercury 1995 115 runs well until below 1000 RPM

    That's one of those 2+2 motors, below about 1800, it is only running on 2 of the 4 cylinders, so if one of those quits the engine will die. Check all the wires going to the stator for Continuity, as the stator is moved, as the wires do flex, and perhaps is opening, also look for signs of...

    How to take out rounded drain plug on force 85? Is there a way to drain without taking it out? Like pumping out the fluid maybe?

    Popping and revving?

    Did it run before you replaced the Head Gasket? When you had the Head off, did you check it for Warpage, and/or Lap it? You say the carbs are fully closed at Idle, are they still fully closed at "just above Idle"?

    Engine Swap

    With the carb I suggest, and the Vortec Heads you will get close to 300hp, that is with the stock Mercruiser Cam Grind Beware that Cams that are great for cars/trucks are 99% of the time not very good for boats, so pick your Cam carefully

    Engine Swap

    The OEM carb will likely be too small for the larger engine. Rejetting wouldn't solve anything. Add to the fact that larger engine will require more air at Idle which will mess up the Relationship between the Throttle Plates and the Idle Transfer Slots, on a carb sized for a smaller engine If...
