    BigTwin prop

    Hi!<br />My 1963 Evinriude BigTwin is in dire need of a new propeller. Is it possible to get a more efficient and newer design prop than the cone shaped prop that was originally fitted. I have to admit that I know very little about props and thier design. On newer models of outboard engines...

    Spark plug leads

    Hi guys!<br />Quick question if I may! The caps that push onto the spark plugs on my 64 BTwin appear to be of the moulded type which are part of the actual HT leads.

    Clutch dogs

    Hi Gents!<br />My old 6340hp bigtwin has done me proud over the summer especially after the usual cooling problems that everyone seems to have at some time or other and replacing the coils etc. The only worry I have at the moment is the occassional jumping out of gear now and then.

    Welding question

    Hello!<br /><br />This is probably a silly question but I like to think its better to ask than be sorry.<br />I want to do some welding on the transom bracket of my 63 bigtwin.
