Congratulations. Start with getting your Owner's Manual and the Shop Manual for reference. Then search on YouTube for the annual maintenance tasks such as: Oil Change, Spark Plugs, coolant check, polish and wax, grease trailer axles, winterizing steps. Then search for less-than-annual tasks: pump bearing lube, visual inspection of impeller and wear ring. Keep in mind that your 4-Tec is in about a million PWCs, so don't be discouraged if the best videos you find are not on a boat, but on a ski.
