Reply To: Mercury KD-4 Cast Aluminum gas tank seam leak

[green-thumbs]

Kiekhaefer cast aluminum gas tank evolved, apparently in response to problems with early tanks, The twin tanks come with and without the fore
and aft hex socket screws. several variations of fuel outlet boss, and
perhaps a bit more metal here and there. Rewind starter requires 4 screw holes in upper tank half to mount starter.
Tanks for single cylinder models also have variations.
We are probably better off not knowing what went into tank sealant and
gasket. I assume the worst and work and work over wet newspaper
when removing old gaskets then wet mop,
