    1981 90hp seized - what do I do?

    I recently bought a boat with a 1981 6 cyl. 90hp merc with a seized engine (knowingly, it was a good deal for the boat even without the engine). The flywheel won't turn at all - not even the slightest bit. I pulled every plug and discovered the very bottom (Cyl 6) had quite a bit of rust on the...

    Anybody from the Vancouver, b.c. area?

    My new favourite lake now has to be Chilliwack lake. I went up there on Sunday and it was absolutely gorgeous. The boat launch is made for smaller boats (less than 20ft they say) and it doesn't have a dock so you'll have to get wet when launching, but it is amazing and totally worth it. Since...

    5.7L 250hp year 200(4?) no spark.

    *Long story so grab some popcorn and enjoy* So, last summer my dad and I took out his 21' 2003 Maxum 2100sc with a 5.7L 250hp mercruiser to go camping. Now, keep in mind this is my father's first boat (story of his first ever docking experience at the bottom), and he has owned this boat since...

    Tach for 1975 Mercury 500 thunderbolt

    Does this look a bit more familiar? You can see that the brown wire connects to a terminal on the switch box, which in turn connects to the rectifier. You can also simply bypass the switch box and connect the brown wire directly to a rectifier terminal (connected to a terminal with a stator wire...

    MerControl tachometer setup

    Hi everyone, I have a teleflex tach that connects to the MerControl box via tach harness, but i cant get it to work. The gauge reads about 400 RPM when not plugged in, then when plugged in (and engine running) it drops to 0. Can someone tell me how to hook it up properly? The motor is a 1971...

    1971 Merc 800 80hp wont stay running

    So I took the boat out to the river yesterday only to find that when I start it, it only lasts about a minute at best. Fuel tank is full, fuel primer bulb is hard, fuel tank vent is open, no fuel leaking anywhere... I'm clueless! (Hence the name). I got this boat through a trade for a go kart...

    1969 Merc 7.5 hp pee hole?

    I've got a 1969 Kiekhaefer Merc75 7.5hp 2 stroke red stripe motor serial no. 2535229 from Toronto, if that helps any. The motor hadn't run for over 10 years, yet it started up fairly easily, but there was no pee coming from anywhere. I took it in to a local marina repair shop for them to fix it...
