    On-Line Manual for older Merc??

    I am trying to find information (specs) that I can download. The engine is a 71' 800. I tried Biggerhammer and it was only for newer engines. Does anyone know a site that I can use to get information and stats for older motors. Thanks

    Rebuild 71' 800 Carbs - How Difficult??

    I was thinking of removing, cleaning, and rebuilding the carbs on my 71' 800 this fall. I can do this on a car, but have never tried it on a outboard. I don't have a manual at this time, but am trying to locate one on Ebay. How difficult is this to do if 10 = 'DON'T EVEN TRY" and 1 = MY SON...

    Lower Unit Questions - 71' 800

    I was changing the lower unit oil on my Merc 71' 800 and noticed there are two plugs on top. One says vent, which I know is where you look to see when the oil is full. But the other is called flush. It is a plastic screw-in plug rather than a metal one...anyone know what this is? Also, are...

    Stupid question about sealing scratches on bottom of the boat

    I have used JB Weld for just about everything with success....can it be used on the bottom of my fiberglass boat to seal scratches from continuous beaching? I actually see some under there from a previous owner. I am planning to paint my boat this fall anyway.<br /><br />Thanks

    Fiberglass - "To Paint or not to Paint, that is the question."

    I just had a friend tell me that I could not paint my fiberglass boat. He said that it had to be gelcoated because the paint would not move with the fiberglass. I have paint that has epoxy in it and it says it is for fiberglass. My understanding is that I needed to clean the hull and then...

    What about DOLPHINITE ACRYLIC LACQUER paint??

    I have one quart of this paint. I won it on Ebay. It says it is for marine use. I have an older boat that needs some repainting. I wanted to see how this brushes on on the bottom of the boat before going any farther. If it looked somewhat smooth, I would try the rest of the boat. It does...

    I have a 71' 800 Merc. Question, Is it better to run the gas out the carb right before pulling it out of the lake or not? I tend to use the boat weekly.<br /><br />Thanks

    Tilt/trim wiring question

    My boat has an aftermarket tilt and trim. The maker on the side is CMC. There is one switch at the front of the boat, but none on the back. I would think that I could splice into the wires going back to the unit and add a switch so that I could use it from the rear of the boat. Anyone know how I...

    Installing Starter Questions

    I am reinstalling a starter on a 71' model 800. The main wire harness coming from the controls has one large red wire and one large black wire. It has been awhile since I pulled this apart, but I am assuming that the large black wire just needs to be grounded. Is that correct? I know that a...
