    Lower unit service. Advice needed please.

    I am going to service the lower unit on my 1980 Johnson 55. (55EL80C) <br />There doesn't appear to be anything wrong down there, but the engine is new to me, and I don't know when it was last done.<br /><br />Where I live, I can't buy Johnson spares off the shelf.

    Idle orifice question.

    I have just stripped down the carbs on my 1980 Johnson 55 to clean and rebuild.<br /><br />In my manual, it says the pre 1980 engines were fitted with 0.045 idle orifice jets, but that these engines had a bad idle. So, the 1980 on engines were fitted with a 0.046 jet, which improved the idle...

    Idle adjustment

    I have a 1980 Johnson 55, 2 cylinder. My engine seems to be idling too slow, although it does keep running and is fine at all other speeds.<br /><br />I've learnt, through this board, that I should adjust the idle speed to 750 rpm, with the boat on the water and the engine in forward.<br /><br...

Garmin say that the unit will work at high speed, but when I took it out today, the display disappeared at anything over 8 knots and the unit started giving false depth readings, ie 97 ft when I know the depth was only 30 ft.<br /><br />I followed...

    How do I balance my trailer?

    Hi<br />I've just bought a boat with a new trailer and I'm not sure how to balance the outfit.<br />When I first hitched the trailer to my car, the rear suspension really dropped. The boat is also difficult to manouvre as it seems there is too much weight forward.<br /><br />I moved the boat...
