How to Select the Right Propeller for Your Vessel
Selecting MerCruiser propellers for your craft may seem daunting at first. Your “right” choice depends on which sterndrive engine has been installed on your vessel. And if your sterndrive is/are Mercury® MerCruiser®, the next question is “which one?” Mercury has been a premier manufacturer of sterndrive engines for over 75 years. Regardless of your sterndrive model or its age, Wholesale Marine carries the right MerCruiser propellers, from Michigan Wheel, MerCruiser and Turning Point for your boat.
Selecting the right propeller for your boat and engine combination is based on several factors including the wide open throttle (WOT) operating range for your inboard. Boat owners should select their boat’s propeller relative to maximizing their boat’s performance, yet allow your engine to operate safely within its specified rpm range. Here are some key factors to consider when shopping for MerCruiser props:
- Propeller Size: This is determined by two sets of numbers- the diameter and the pitch.
- Diameter: This number is 2x the distance from the center of the hub to the tip of the blade.
- Pitch: This is the theoretical forward movement of a propeller throughout one revolution.
- Cupping: A recent advance in propeller blades is the inclusion of a slight curve to the edge of the blades to increase acceleration. This blade cupping contributes to a higher top end speed as well.

FAQs
How do I choose the right MerCruiser propeller for my boat?
Selecting the right MerCruiser propeller depends on factors like your sterndrive engine model, propeller size (diameter and pitch), and your boat’s wide open throttle (WOT) operating range. You should choose a propeller that maximizes performance while keeping the engine within its recommended RPM range.
What is the difference between aluminum and stainless steel MerCruiser propellers?
Aluminum propellers are more affordable and lightweight, making them a great choice for casual boating. Stainless steel propellers, on the other hand, are more durable and provide better performance, especially at higher speeds or in rough conditions.

Yes, Wholesale Marine offers both full propeller kits and individual propellers. If you're a DIYer, we also provide the necessary hardware and specialized propeller wrenches to help with installation.
