    To flush or not to...

    I use my Waverunner in fresh water only. Is it necessary to flush the engine after each use or at least periodically? All I have been doing is running it for a few seconds after it has been taken out of the water.

Right after I launch it, when I turn the key it just makes a clicking noise, after a few more trys it will eventually turn over and starts right up.

    General question about starting

    I bought an older 76 bowrider with a 66 merc 4cyl 65hp. I took it out yesterday and much to my relief she ran pretty well. My question is about the controls. There is a black button to hold down while starting. Is this a choke? Does it need to be held down every time I start it or only when its...

    Should the motor be locked down?

    I am new to boating and have a 16ft bowrider with a 1966 65hp merc. I have a dumb question.. It is not power tilt and there is an adjustment with about an eight inch removeable rod where it can be locked into one of the holes for a certain tilt angle. Should I start out with it all the way down...

    Merc gas treatment AND seafoam

    I had mixed up a fresh 6 gal batch of gas and added a couple ounces of the Merc brand concentrated gas treatment and stabilizer. Since this motor hasnt been run in a few years I also added about a half can of seafoam to the gas as well. Will this hurt anything? Is it too much of a good thing?

    I just bought an older 16 foot tri-hull fish/ski boat with a 1966 65hp merc 4cyl. It has a 2 blade prop and I would like to know if there is a better prop I can put on it, maybe a three blade. With all the different types out there, pitches etc.. I just dont know what to get. Primary use will be...

    Getting rid of old gas

    I have about 5 gal of 4 year old 2 stroke mix sitting in the outboard tank.. There is no disposal site in my area and I need to get rid of it. Does anybody know if I could mix it with about twice as much fresh gas in my car and run it? or would that screw up the injectors or something else?

    Stupid, stupid me....

    About a month ago I decided I wanted a boat. I shopped around for about two weeks and learned what I could about them. I found one on e bay that looked pretty good. A 76 Thundercraft with a 71 Merc 650. Although it is an older boat and motor, it seemed to be well taken care of. I went ahead and...

    History Lesson

    I have recently purchased a boat with what Im told is a 70's model (possibly 76) merc 4cyl 65hp outboard. I dont have the boat yet but Ive been reading up on the older motors. I notice that Mercury apparently made a 65hp in both 3 and 4cyl versions around the same time. Does anybody know for...

    Outboard motor cover

    Is there such a thing as a storage or travel cover that covers the entire outboard motor? The reason I want one is because the lake close to me has a lot of dirt roads and I want to keep dirt and contaminants out of it.<br />Thanks

    Motor stored for 4 years

    I just purchased a boat with a 70's model merc 65hp, 4cyl, 2 cycle outboard. The boat/motor has been stored since 99. The owner said that before storage it was run out of gas, oil fogged and stabilizer was put in the gas. At the same time it had a new starter, rotor, cap, wires, and plugs...
