21.5' Campion fishing machine, 150 2 stroke yamaha oil injected, 9.9 4 stroke yamaha. I have a complete spare motor (not running) 200hp Yamaha that is a parts motor. I'm trying to decide what i should carry with me on the boat while fishing for those repairs that I can do on the water. obvious - prop, castle nut ect, spark plugs, various hoses ect, extra litre of oil, anything else you might consider carrying? I sometimes overnight on the boat and can be 2-3 hours from my port. thanks
