      I too intend replaceing the Blakes seacocks with stainless steel ones. But one must remember to change the skin fitting to stainless steel as well. Do not install stainless seacocks on bronze skin fittings, the results can be increased corrosion between the different metals. Tenancier is hull No. 106 I think offhand, and is berth at Southport Yacht Club, Queensland, Australia, so the boat is always in warm salt water, maybe UK owners do not have the same corrosion rate/speed as experiecced here. Thankyou all for expressing your views, a great read. Regards, Keith Morris.

      Its not unusual to have Marleon seacocks stiffen to the point of breaking off their handles.  Frankly, any seacock will benefit from regular operation and a light lubrication with the appropriate gunk on an annual basis. 
       
      Note: some seacocks have rubber parts and should not be lubed with petrochemicals.  Silicone grease is good for most anything.

      Hi Gang, When I re-fit LaBo I decided to go all Marelon, No corrosion, no electrolysis issues-nada. ..the only drawback is that they will melt if the boat catches on fire...hmmm.
