Frequently Asked Questions
What is the difference between OEM and aftermarket outboard parts?
OEM parts are made by the original engine manufacturer. Aftermarket parts are replacement parts made by other manufacturers to fit the same application. Pro Marine provides quality OEM specification aftermarket products designed for marine maintenance, repair, and rebuild work.
How do I find parts for my outboard engine?
Start by selecting your outboard brand, then choose the correct engine system category. Use your model number, serial number, horsepower, and year range to confirm fitment before ordering parts.
What information do I need before ordering outboard parts?
You should have the engine manufacturer, horsepower, model number, serial number, and any OEM part numbers from the original component when available. This helps avoid ordering parts that look similar but fit a different engine family.
Are aftermarket outboard parts reliable?
Yes, quality aftermarket outboard parts are commonly used by marine mechanics and rebuilders. Pro Marine offers OEM specification aftermarket products for many common outboard repair, maintenance, and rebuild applications.
What brands are included in the outboard category?
This category includes Chrysler Force, Honda, Johnson Evinrude E-tec, Mercury, Suzuki, Tohatsu Nissan, and Yamaha outboard parts.
Tip: Before ordering outboard parts, confirm your engine brand, horsepower, model number, serial number, and year range whenever possible.
