    '81 50hp Merc Carb/Fuel Pump(s)

    Running across the lake last weekend at about 7/8 throttle, it felt like the motor just fell on it's face. After that, low speeds are fine, but when you open the throttle up it bogs down. While my daughter drove I was able to pump the primer bulb and it would act normal allowing us to get back...

    Electrical question, '80 50HP Merc

    I was doing some electrical testing on my motor this weekend to try and find out why the starter motor barely turns the motor over and gets very hot. I read on here that 3 out of 5 starter motors get replaced when there is actually some other problem. <br /><br />I connected the positive lead of...

    '80 50hp Merc starter slow / hard starting

    The starter on my Merc recently began "lugging" for lack of a better word. It spins slower than normal the first time you try starting it for the day. After cranking for a few minutes, it picks up and acts normal for the rest of the day. The battery is fully charged. Any ideas on what could be...

    1980-81 50hp Mercury Prop ID???

    I need to order a new prop but I don't know the diameter needed, had to cut it off in lil bitty pieces as it was frozen on shaft w/spun hub. The number on the prop is 48 73136A 4 13P, is there somewhere you can look that # up? <br /><br />I'm thinking 13 spline, 13 pitch, thru hub exhaust, have...

    1981 50hp Merc, spun prop hub?

    I was wondering if this year model / size motor used the rubber hubs in the prop? I was running about 3/4 throttle and all of a sudden the engine revved up but speed fell off. It will start to catch at first, but will not get up on plane without the rpm's rising and speed falling off, seems it's...

    How to siphon gas

    I wasn't there unfortunately, but my brother called me one day hysterical about what had just happened to him. He was attempting to remove the old gas from a fixed gas tank in a Nitro bass boat to replace with new as it was several years old. He was using a piece of small diameter air hose to...

    81 Merc Control Box

    I have a 1980 or 81 Mercury 50 HP SN#5799294 on a 1981 Bass Tracker III with the trim switch on the consol (not integral with the motor wiring harness). I am looking to get a newer model control box / harness assembly for it but need to know if it will plug up to my existing motor harness since...

    Tip of the week...

    I think I figured out why they say to disconnect the battery if the boat is to be stored for a long period of time...<br /><br />I recently purchased a basstracker with 1981 model Mercury 50hp that had been sitting for approximately 6 years, with the old battery still connected. I noticed the...

    1980-81 Mercury 50 HP - Thermostat?

    Howdy all, new to the board (1st post), but not to the site.

I have replace the entire water pump assembly in this motor and started it for the first...
