    Biggest problem with boating?

    inflation , the cost of boating is getting stupid . the " bust out another thousand (BOAT) " saying is now no longer relevant. not much can be done to your boat for a $1000 bucks these days.

    1990 4.3 block and 1995 heads, which rocker tightening specs to follow?

    there are a couple of people here that will help you with timing that motor to the correct spec with whatever the digital distributor you have fitted. you may still have to use the shunt wire depending on what set up was installed , i think 6 deg is a little shy ? if you have HEI set up ...

    1990 4.3 block and 1995 heads, which rocker tightening specs to follow?

    you have non adjustable rockers , if the book says 40 then that is where you should put them. measure all your push rods to be double sure that they did not get mixed up or the incorrect ones fitted , as i posted , there are 3 different lengths. you can check for a soft lifter by pushing down...

    1990 4.3 block and 1995 heads, which rocker tightening specs to follow?

    well that sheds a light on why your nuts backed off , you have something going on there with the rocker posts on your heads . i cant remember off hand , but i think the rockers are also different adjustable and non adjustable so do a comparison before you continue to use the motor.. ? can you...

    1990 4.3 block and 1995 heads, which rocker tightening specs to follow?

    put the nuts on a metal plate , on the top of the nut you will see indents like a square pin punch has been used . give those areas a " strait down" whack with a punch again , this will tighten the threads again so the nuts wont back off . personally , i don't like using thread sealers or thread...

    or get a cardboard box and chop it up to shield the oil from the push rods. start the motor , starting with #1 cylinder back each rocker off or tighten till it just clicks then crank down 1/4 a turn . lash done , clean up mess ,put covers back on and go boating :). OP , i found there are 3...

    Still, still stuck with no spark

    the stopper switch i am addressing is on the motor , not the kill switch, it is to stop run on if the 2 stroke starts pre igniting / 2 stroking if the motor runs lean , that is what i think it does , guessing the mercury guys here will explain its purpose in more detail.

    Still, still stuck with no spark

    not knowing the model of your motor , it may have a "stopper switch" .some early motors had them but not sure if the eliminated them on 96 motors.

    Embarrassing question

    adding a double dose is not the answer , add what is required to the amount of fuel you are putting in , 50;1 or there about . 100: 1 is border line for hit or miss as far as engine damage , those V4s are a robust little sod , guessing if you did not do high RPM running your motor will be a...

    Embarrassing question

    you may have broken the power band if you ran it with no oil . seriously: add 20 ml of oil to every liter of fuel ,i don't know gallons and ounces off hand but the mix above equates to around 50:1, that is safe for most 2 strokes requiring pre mixed fuel. FWIW , that motor will run fine @ 60 or...
