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 25W50 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

If you do not want the kit with included 25W50 engine oil, use the no-oil version and select your oil separately.

Mercury 450R V8 Replacement Belt
Mercury 8M0159595 Belt
The Mercury 8M0159595 Belt is a replacement belt for compatible Mercury 450R V8 belt drive systems. A worn or damaged belt can cause squealing, slipping, charging issues, overheating concerns, or poor accessory drive performance.
When replacing this belt, inspect the belt tensioner and pulley assembly at the same time. The related Mercury 8M0164060 tensioner assembly is linked below.
Compatible Applications
| Engine / Application | Part Number |
|---|---|
| Mercury 450R V8 belt drive system | 8M0159595 |
Verify your engine serial number and original belt part number before ordering. Mercury belt lengths and belt drive components can vary by model and serial range.
OEM & Cross Reference Numbers
| Type | Part Number |
|---|---|
| Mercury OEM | 8M0159595 |
Related Tensioner Assembly
Mercury 8M0164060 Tensioner Assembly
If the belt is worn, slipping, squealing, or tracking incorrectly, inspect the tensioner assembly as well. A weak or noisy tensioner can shorten belt life and cause repeat belt problems.
What This Part is Used For
The engine belt transfers power through the belt drive system to related engine accessories. Proper belt condition is important for quiet operation, correct pulley tracking, and dependable accessory drive performance.
A belt should be replaced if it shows cracks, glazing, fraying, uneven wear, contamination, slipping, or noise. Because the belt works directly with the tensioner and pulleys, those parts should be inspected during the same service.
Key Features and Benefits
- Mercury OEM replacement belt
- Part number 8M0159595
- Used on compatible Mercury 450R V8 belt drive systems
- Helps restore proper belt drive operation
- Recommended replacement when the belt is cracked, glazed, noisy, or slipping
- Related Mercury 8M0164060 tensioner assembly linked above
- Good service practice is to inspect the belt, tensioner, and pulleys together
Common Signs of Belt Wear
| Symptom | What to Check |
|---|---|
| Squealing or chirping | Worn belt, weak tensioner, pulley alignment, or contamination |
| Cracks or fraying | Replace the belt and inspect pulley surfaces |
| Glazed belt surface | Slipping belt, weak tensioner, or worn pulley contact |
| Uneven belt wear | Misalignment, tensioner wear, or pulley damage |
| Repeat belt failure | Inspect tensioner assembly and pulley system before installing another belt |
FAQ
What is the OEM number for this belt?
The OEM part number is 8M0159595.
What engine is this belt commonly used on?
This belt is listed for compatible Mercury 450R V8 belt drive systems.
Should I replace the tensioner when replacing the belt?
Not always, but the tensioner should be inspected during belt service. If the
tensioner is weak, noisy, binding, or the pulley is worn, replace it with the
related 8M0164060 tensioner assembly.
Can a bad tensioner damage a new belt?
Yes. A weak, worn, or misaligned tensioner can cause slipping, noise, uneven
wear, and premature belt failure.
When should this belt be replaced?
Replace the belt if it is cracked, frayed, glazed, contaminated, slipping,
noisy, or showing uneven wear.
Do I need to verify fitment?
Yes. Always verify your engine serial number and original belt part number
before ordering.
