- Contaminated engine oil: use the correct oil change kit with the proper oil filter and drain gaskets.
- Milky or dark gear lube: inspect the lower unit and confirm whether your kit includes gear lube for service.

- Unknown service history: perform a full 100-hour or annual service before troubleshooting deeper engine issues.
Frequently Asked Questions
What is the difference between a service kit and an oil change kit?
An oil change kit usually focuses on engine oil, the oil filter, and related drain gaskets. A service kit may include additional maintenance items such as fuel filters, spark plugs, seals, gaskets, gear lube when applicable, and other parts used during 100-hour or annual maintenance.
Do all service kits include gear lube?
No. Some kits include gear lube and some do not. Always check the individual kit description to confirm whether lower unit gear lube is included before ordering.
How do I find the correct service kit for my engine?
Start with your engine brand, horsepower, model number, serial number, and year range. Many kits are grouped by engine family or horsepower range, so confirming the exact engine information helps prevent ordering the wrong kit.
What is a 100-hour service kit?
A 100-hour service kit is designed to support routine scheduled maintenance commonly performed after 100 hours of operation or once per season. Contents vary by brand and engine model, but may include filters, spark plugs, gaskets, oil, and gear lube depending on the kit.
Are aftermarket service kits reliable?
Yes. Quality aftermarket service kits are commonly used by marine mechanics, boat owners, and rebuilders. Pro Marine provides quality OEM specification aftermarket products for marine maintenance, repair, and service applications.
Should I replace everything in the kit at once?
For scheduled maintenance, it is usually best to replace all included service items at the same interval. This helps create a known maintenance baseline and can prevent repeat service work later in the season.
Tip: Before ordering, compare your engine model and serial number to the kit listing and check whether the kit includes engine oil, gear lube, filters, spark plugs, and drain gaskets.
