    Serial Numbers Missing

    Hi Guys, We recently bought a goverment seized boat. The boat is about a 30' 1997, Carrera. It has twin 200hp Mercury Outboards. Engines looks great and compression is good. We want to change the thermostats, hoses and water pumps prior to trying to starting the engines. Problem is, we...

    Ignition Problems

    Yesterday I put my 16' 1977 Evinrude 75hprwed boat into the water. I started it up and allowed it to run for a few minutes. After about five minutes it died and would not restart. Thinking it was the powerpack, I replaced it with one I knew was good (I keep a spare). It still didn't start. I...

    Carb Help

    Guys, I have a 1977 Evinrude 75hp. I recently rebuilt the engine and have broken it in. Prior to that I also rebuilt the carbs. According to the manual I do not have 1977 carbs on the engine. It appears to be 79-82 carbs because they have 3 orifice holes instead of two, one top center, one...

    Leaking Exhaust Gasket

    I recently rebuilt and successfully broke in the engine with no problems. For the 3rd time I'm having to replace the outside exhaust gasket on a 77, 75hp Evinrude. It runs great until the gasket leaks, (like a high pressure stream). After it starts to leak, the engine sounds like it's...

    WOT Speed

    What is the top speed you should get at 5500 rpm with an Evinrude 75hp installed on a 16ft deep v hull boat. Engine sounds great but seems as though its not getting everything it should. Not sure of the prop specs.

    Hard Starting after rebuild

    I have a 1977 75hp Evinrude which I rebuilt. I had the block rebored and installed new pistons, the whole nine yards. I tried starting the engine today but had no luck. It is turning very slowly and really seems as though it need lubrication on the rings. I oiled the pistons before...

    Advice to guys with older engines

    My 1977 75hp Evinrude was running rough. It would die unexpectedly after running good. A few month ago I did a compression test and found all the clyinders around 110. Saturday I did a compression test and got 110 on the top cylinder, 110 on the 3rd cylinder and nothing (0) on the 2nd. I...

    Planing Problems

    I have a 1977 Johnson on a 16" fiberglass deep v-hull boat. I have what is called a kickplate on the transom to raise and lower the engine. Problem is that when the engine is lowered in gear, I don't get planing power when I throttle the engine. When I put the engine in gear and increase the...

    Running without thermostat

    Rich gas misture

    I have a 1977 Johnson 70hp engine. I ran it a couple of twice this month, but it has been sitting up for a while. I removed the spark plugs and found all three black and oily. After reading the post and following the suggestions, I bought the kits and pulled the carbs. I replaced the floats...
