"Everyone does this differentl
"Everyone does this differently. You should check your owner's manual. You should check the prop nut and cotter pin, change the oil in the lower unit, and many change their plugs and fuel filters. All of this is easy, and within the means of most owners. If the waterpump impeller has not been changed recently, you should consider that as well. This is a more difficult repair. Many boat owners do their own, not everyone is capable. Beyond that, if the boat has been sitting without use, the carburetors might be gunked-up. Cleaning and installing new seals and gaskets is also a job that many do themselves, but not everyone is capable. You should also check the condition of all of your fuel lines, fittings, and clamps. Make sure your flares and coast guard equipment is in-date. Make sure the battery electrolite level is proper, and that the battery terminals are clean, and the battery fully charged. The more of this you learn to do yourself, not only will it save you $$, you will be less likely to get stranded if you do have a problem, because you can learn enough to do your own emergency repairs."
