RE: .40 or .60 nitro engine???
buy it if you get a good deal they are good engines.a tip for you if your boat flips ,disconect fuel lines and turn the prop over with electric starter and open carb let all the water come out of carb dont stand in way or youll get wet!!,reconect fuel lines and start her up .this burns any water and stops it rusting,run a full tank through it after a dunking and she will be good as new.a spray of wd40 after doesnt hurt either,then you can add some after run oil in the carb too.
