I bought the original mercury workshop manual and its great. Now i understand why you guys stress on buying a manual. <br /><br />Anyway im going to go ahead with removing the powerhead and i just realised im going to face problems with removing the bolts. And i have read whole heap of topics on the subject and have found one explaining to heat the screw up with a butane torch and then cool it down with WD40 by spraying it. We have this product which is called ROST OFF and i think its better than wd40 because its penetrates deeper and is a tiny bit corrosive. Anyway about the torch, I have this torch which is basically the cylinder butane tank and on the top it has the actual torch coming out ... I think its the one used by plumbers. Will this be fine or will i need to get a Butane/Oxy combo and a precision torch?..<br /><br />Anyway my problem is water is leaking out from the bottom of the water jacket cover. <br />I believe that this is caused by a tiny puddle of water which always stays behind after use and it slowly ate through to the outside through the block. I was wondering is this repairable or will i have to use another block? I have another motor which i bought from a mechanic who came in with a problem with the LU but in the end traded in the whole motor.<br /><br />Thanks guys "_"
