Frequently Asked Questions

What is the difference between OEM and aftermarket marine parts?

OEM parts are produced by the original engine manufacturer. Aftermarket parts are replacement parts produced by other manufacturers to fit the same application. Pro Marine provides quality OEM specification aftermarket products for marine maintenance, repair, and rebuild applications.

How do I find the correct inboard or sterndrive parts?

Use your engine model number, serial number, drive model, and horsepower information to confirm fitment. Sterndrive applications may also require the drive serial number for accurate parts matching.

What brands are included in this category?

This category includes Mercruiser, Volvo, OMC, Crusader, Pleasurecraft, Indmar, and Chrysler marine engine applications.

What are common signs my sterndrive needs service?

Common warning signs include overheating, water in gear lube, vibration, difficult shifting, drive noise, poor acceleration, bellows leaks, and excessive corrosion.

Are aftermarket sterndrive and inboard parts reliable?

Yes. Quality aftermarket marine parts are commonly used by marine mechanics and rebuilders. Pro Marine offers OEM specification aftermarket products for many marine engine and sterndrive repair applications.

 

Tip: Before ordering sterndrive or inboard parts, verify the engine model, serial number, and drive model information whenever possible.
