Reply To: 1962 Evinrude 40 HP fuel leaking around drain valve

[JACQUES]

hose looks like the oil return hose that send crankcase  fuel oil residues back to the top bearing  to oil it  whereas the other picture  shows  the purge valve cover.  the hose may have a split in   it causing  leak  or the purge  valve cover   may be leaking as well.

has suggested  by fleetwin try to oberserve exactly where it  leaks or one possibility  is  if you  use some UV light  dye  liquid in a small  fuel  supply  fed into the carb.  Run the engine and  use  a UV light to “light” up the leak

I hope you can see attached pics because that silly blue circle still shows up  🙁  for me anyway

 

your 62 40 hp  is cousin with the RD24 johnson.  this service manual is always useful  in servicing oldies
