How Much Does It Cost to Fix a Spun Prop Hub? A Boater’s Guide

If you’ve encountered issues with your boat’s propeller, you may be dealing with a spun hub. This common problem can significantly impact your boat’s performance, but how much will it cost to fix? Let’s dive into the details of spun prop hub repair costs and what you need to know.

What is a Spun Prop Hub?

A spun prop hub occurs when the rubber or plastic insert between the propeller and the propshaft wears out or breaks. This can happen due to normal wear and tear, sudden impacts, or aggressive acceleration. When the hub spins, it fails to transfer power from the engine to the propeller effectively.

Signs of a Spun Prop Hub

Some indicators that you may have a spun prop hub include:
• Decreased boat speed and power
• Difficulty reaching plane
• Poor fuel efficiency
• Excessive vibration
• Lack of forward motion despite engine operation

The Cost of Fixing a Spun Prop Hub

The good news is that repairing a spun prop hub is generally an affordable fix. On average, you can expect to pay between $50 to $150 for a prop hub replacement. The exact cost depends on several factors:

• Engine type and size
• Propeller material (aluminum or stainless steel)
• Location and labor rates of the repair shop
• Whether you choose OEM or aftermarket parts

DIY vs. Professional Repair

While some boaters may attempt to replace a prop hub themselves, it’s often best to leave this job to the professionals. Prop shops have specialized equipment to press out the old hub and install a new one properly. The cost of professional installation is usually worth it to ensure the job is done correctly and safely.

When to Replace vs. Repair

In some cases, it may be more cost-effective to replace the entire propeller rather than just the hub. This is especially true for aluminum props, which are generally less expensive. However, for stainless steel propellers, which can cost $400 to $700 new, repairing the hub is usually the more economical choice.

Preventive Measures

To avoid frequent prop hub issues, consider these tips:
• Inspect your propeller regularly
• Avoid sudden, full-throttle accelerations
• Be cautious in shallow waters to prevent prop strikes
• Carry a spare propeller for emergencies

Finding a Reputable Prop Shop

To ensure you get a fair price and quality work, research prop shops in your area. Ask for recommendations from fellow boaters or your local marina. Don’t hesitate to get quotes from multiple shops before making a decision.
