    1978 Terry ABF 4.7M, 1977 Merc 850: Power Trim

    The round head slotted stainless screw on the power trim pump/reservoir is where you fill it. Use 5W-30 motor oil or Dextron III ATF, whichever in in it now. The pump/reservoir is self bleeding, but the trim cylinders are not. There is a procedure to bleed them. You might search for it, as I...

    Boat going in reverse instead of forward

    OB gearcases and the lower portion of stern drive gearcases on Mercury/MerCruiser are nearly identical, for both CW and CCW models. Johnson/Evinrude gearcases are very similar to Mercury. Not sure about Cobra and it's family members. The CCW gearcases have a heavy duty thrust bearing behind...

    Boat going in reverse instead of forward

    Mike, I was talking about an inboard, not an I/O. To my knowledge, I/O motors never ran CCW. They used counter rotating gearcases for CCW rotation. Post #19 to which you refer was not written by me.

    Boat going in reverse instead of forward

    Mike, Inboard engines were often designed to run CCW. As far as I know (Mercury direct reversing motor excluded), outboards were not.

    Replacement Cables

    Shift and throttle cables are specific to engine type. What do you have? MerCruiser?

    Boat going in reverse instead of forward

    This should be reposted in the Mercury/Force forum. Mercury OBs often have this issue, and it is easily correctable. I am not sure about Force products. There are design differences between a CCW and CW gearcase. Changing the prop to make it work correctly can easily destroy the gearcase.

    Temperature switch circuit 2000 Johnson 150hp

    OK, D/C the two wire sensor. Connect a 1 wire sensor to the tan wire for overheat warning. Have you checked the pulse limiter, vapor pump, vapor separator cover?

    Temperature switch circuit 2000 Johnson 150hp

    SLOW limits the spark advance and keeps the engine RPM down. A healthy waterpump will pump at 30PSI plus. Of course, there is no way to check this without a water pressure gauge, which I do recommend. Obviously you need to repair/replace waterpump before using boat. I recommend a full kit...

    The newest outboard from Mercury

    Gee, a 600HP pontoon boat...Just what I always wanted. $77K seems pretty high. I would expect you could get more HP for less $, with multiple engines. And as my neighbor says, the more engines the more fish you can catch...... The torque on that rotating gearcase must be massive. Kinda like...

    how to change a prop on mercruiser alpha one outdrive 4.3L 2010 bayliner BR 195

    The nut is usually easy to remove. You have bent all 3 of the "legs" of the spider washer toward the rear of the boat to allow the nut to turn, right? A large screwdriver usually works for this. A 2X4 from the zinc fin behind the prop to the "neck" of the outdrive will jam the prop safely, to...

    Temperature switch circuit 2000 Johnson 150hp

    OK, looks to be a 60* V6 2 cycle motor. It should have the SLOW mode, activated by either temp sender. Where does your motor show "hot"? On the System Check gauge? I would disconnect the 2 wire sensor and see that the warning goes away. The ignition must be turned off to reset the hot...

    Temperature switch circuit 2000 Johnson 150hp

    What is engine model number? A lot of Johnson outboard motors go into SLOW mode when they overheat. They often have a horn that signals overheat.

    Firestone boat motor

    Old Johnson/evinrudes also used them on their fuel pumps. Try 1959 big twin motors, from 25-40HP. If those are too small, the fat fifty from '58 - '59 used them as well.

    Trim

    That motor should have a 2 wire PTT motor. Relays provide ground to the motor (up relay to blue wire on PTT motor, down relay to green wire), when not energized. When energized, relays provide power to their respective wires. Since only one relay is energized at a time, either up or down...
