    YAMAHA F50 RUNNING POORLY IN MIDRANGE

    This is a '95 F50 that was running great last weekend but this weekend started acting up. It starts great, idles great but when you throttle up to about 2000 RPM, it starts to miss terribly. If you throttle up into the higher RPM range (maybe around 4000 or so) It levels

    75 hp 1995 Mariner prop won't rachet in reverse after prop seal and water pump change

    I bet this has already been answered but I can't find it. I changed my prop shaft seals a few days ago and while I was at it, I replaced my impeller on the water pump. Got it all back together and WHAM...I have forward, I have neutral and I can even put it in reverse. However, the prop won't...

    '95 75 hp MARINER CONSTANT ALARM

    If I turn the key to the on position my temp alarm beeps, then shuts off like it's ready to start. However, if I bump the wires under the dash, it goes to a constant beep signaling that my temp swith has an issue. This happens with the engine cold and my oil pump is disconnected (using premix)...

    Loaded up!!!!

    My 1995, 75 hp Mariner runs fine at WOT but has started to load up at idle and just above idle. It's been running pretty well the past two weeks and this just started to do this this past weekend. Thanks in advance for any help.

    Another tach problem

    I have a 1995, 75 HP Mariner. The tachometer doesn't work when the motor is running. However, if you turn the key on without cranking up, the tach will slowly creep up. Once the engine cranks, the needle pegs to zero and won't budge. Am I looking at replacing the tach or something more...

    1995 75 HP Mariner Hard to Start on Occasion

    It will cold start but once it warms up is starts to slowly idle down then shuts off completely then SOMETIMES it's hard to start. A buddy of mine thinks the choke solenoid is acting up. Should I be able to see the small plunger at the bottom of the solenoid going up and down when the key is...

    Help with a Quicksilver 3000 control

    I have recently purchased my boat from my widowed neighbor. The control is a Quicksilver 3000 mated to a 75hp Mariner. I understand there was a service bulletin some time back for this controller. I'm working now to find out if it was upgraded. However, I do seem to have another issue with...
