Indmar 8.1L 10 Quart Engine Oil Dipstick

Indmar 8.1L 10 Quart Engine Oil Dipstick. Due to oil consumption and oil sloshing issues when coming off the throttle fast, Indmar found that the 8.1L engines should have a 10-quart oil capacity to avoid low oil pressure damage. The 10 Quart dipstick can be identified by the yellow T handle. If yours does not have a yellow handle replace the dipstick and top off your oil with heavy-duty 40 Oil Only. Engines were originally built and shipped with 15W-40 so make sure to update your documentation and oil cap to 40W.
