Many thanks, Colin.
Errm...no, your plugs should be NGK BUHZW for a Brown band 4 cyl 50 if you're using surface gaps (which is what runs best in those motors). If you want a set of 4 drop me a PM.
You'll need 2 tubes if you're using tubes, or a litre if you buy the pump (far easier but a lot more money)
Need spares,consoles,consumables,hire,training or even a new boat?
