    Evinrude 55 1978 gearcase

    Hello, I have owned Evinrude 55 1978 since 2013 and it's been working well. Now I first time decided to change the water pump impeller and after removing the gearcase I found that a lot of exhaust gases must have been leaked inside there (black soot). In the figure (arrow) it can be seen a leak...

    Evinrude 15 1992 carburetor cover change

    I am installing a new carburetor cover to replace the broken plastic one. I found very strange pins (seen in figure) in carburetor top surface, and I do not have any idea of their purpose except a trial to repair the broken plastic cover, where two pieces were also glued. Does anyone have idea...

    Evinrude 15 1992 Tiller arm low speed

    I've been wondering whether there exists the the low speed knob or not in the tiller arm of my 15 HP Evinrude. It seems that the low speed knob at the end of the tiller has never rotated since the whole handle including the knob seems to be like one piece. Does anybody know if there has been...

    Evinrude 15 1982 Interesting problem

    Starts fine, idle is fine and full throttle is fine whenever I got it to full throttle. It misses for a while when accelerating, but runs well with full throttle. It seems that mid throttle is someway missing. Does anybody have any idea what the reason may be? Carburetor cleaned and floater...

    KUS GPS Speedometer

    I wired a new GPS speedometer (figure) and faced a some kind of interference problem (I guess) while starting my 70 hp Yamaha. There is now a constant voltage (12 v) from ignition switch to speedometer (when turned power on). At this point everything is OK, speedometer gets power, GPS founds...

    Latch

    I found the same latch problem with my Evinrude 6 hp. I don't understand its function. I have a new lower latch, but I cannot figure out how the upper part can be fixed with it. Could somebody help with this by trying to explain its function?

    Evinrude 15, 1980 water circulation

    I have two of those 15 Evinrudes and I am not sure whether the water is circulating properly. In one of these motors there is good water pressure from pee hole (straight water line) while idling and it increases a bit with increasing throttle, but it seems that with full throttle there is an...

    Evinrude 15 1980

    I got this Evinrude 15 hp 1980 and during the first trial it was slipping out of gear. With closer inspection I found that the black cam in the shifting linkage was missing. Now I got this cam and while adjusting a linkage I was wondering which way the threaded rod should be to confirm that the...

    Johnson 9.9 year?

    As you see in the figures, this Johnson is not in its original form. Model plate (J10BACNS) tells that it is 1982, but because there is no power pack, it must be pre 1978, if I am correct? Can anybody tell me how to figure out the year for the upper part. It seems that there is only white cover...

    Yamaha 70 CES (-84-85)

    Does anyone know what is a correct reading for water pressure? I have a racing boat in which the original water inlets of the motor are not working at full speed due to the high mounting of it and therefore I have an additional water intake pipe at the transom. I have heard that there should be...

    Evinrude 55 Triumph (-68)

    When accelerating I have to give a small choke before the engine takes a full trottle. After that it runs well. I have considered this just a minor problem and because it is very easy to give a small choke with automatic choke I have done nothing to fix it. With this information can anyone say...

    1968 Evinrude 55 Triumph

    I wrote sometimes ago that I tried to start my engine with good cranking but I didn't succeed. No spark. Last week I did a new trial with brand new battery (75Ah). First while cranking, I thought that it will never start but then it FIRED with thick blue exhaust from the oil I have put into the...
