It's the same boat we have. Ours came with a few spares: raw water impeller, fuel filter, belts. I've used them and replaced the spares. I started with a few tools (socket set both metric and SAE, Vice Grips, screw drivers, sharp wire cutters, rigging knife, hacksaw blade and holder, digital meter, spare bulbs. Once in a while I discover I need something else that I add. Some things like an air filter, paint, and oil filter I don't keep on board. I won't likely need to replace them as an unplanned event. In a marine enviornment I'm not afraid to go wothouw an air filter. I'd replace a failed one at my liesure. I also carry a fid, small squirt can of light machine oil, electrical tape, duct tape, butyl tape, super lube, small tubes of epoxy, sail tape, needle and heavy Dacron thread, and an assortment of stainless steel fasteners.
