For the jet ski owner

One ski on the board. Oil on the GTI 130 every 50 engine hours. Impeller inspection every 100. The bilge / drain-plug check on the calendar. That is the whole list, and it lives on one due board.

You know the hour meter. Last oil on the GTI 130 was at Harbor Marine, 95 hours and $185 on the invoice. The meter reads 130, so 15 hours are left. Say those numbers to Muse once and the row is written. You run about 15 hours a month through the warm season, which is two weekends of riding. Book the shop for that week and the oil change happens before the hours run out.

Sunday night, ask Muse what's due on the GTI 130. Oil comes back with the 15 hours left and Harbor Marine as the last shop. The impeller comes back with its own hours left: last impeller at 60 and the meter at 130 leaves 30 hours to the next 100-hour inspection. The Worker subtracts and names what is left, and no model sits in that path.

The calendar lines keep their dates. The bilge / drain-plug check is the first Saturday of the month: drain plugs seated, bilge dry. The Saturday a late weekend ride eats does not push next month's check into the second week. A late ride is logged when it happened; the cadence does not drift.

Your shop preference is one ask too. Say it once: always use Harbor Marine on the GTI 130. Muse writes it, and the next oil booking starts at Harbor Marine without you naming the shop again.

The board can call ChatGPT too. Subscribe once and ChatGPT hears when the hours you log put oil on the board, in a signed webhook naming the job and how late. You did not have to ask first.

The day the ski sells, say it once: sold. Muse archives the jet ski and the due board drops it that day. Every oil row, impeller line, and shop you logged stays in the history. If the deal falls through, one ask puts it back on the board.
