OEM Mercury 100 Hour Service Kit With Oil
Mercury 5.7L V10 350HP-425HP Verado 100 Hour Maintenance Kit
This OEM Mercury 100 hour service kit with oil is designed for Mercury 5.7L V10 350HP-425HP Verado outboards. It includes the routine 100 hour maintenance components along with Mercury 25W40 engine oil for engine oil service.
Important: This kit includes engine oil, but it does not include gear lube. Mercury V10 standard rotation and counter rotation gearcases require different gear lube quantities, so gear lube should be selected separately below.
Compatible Applications
| Engine Platform | Horsepower Range | Displacement | Application Notes |

This kit includes Mercury 25W40 engine oil, but it does not include gear lube.
Standard rotation Mercury V10 gearcases use approximately 1 quart of gear lube.
Counter rotation Mercury V10 gearcases use approximately 2.3 quarts, so customers should order 3 quarts for proper service.
If you do not want the kit with included 25W40 engine oil, use the no-oil version and select your oil separately.
