Planning a premium sportfish repower is one of the most critical investments you’ll make in your tournament fishing program. Unlike standard marine engine replacements, sportfish repowers demand meticulous attention to power-to-weight ratios, fuel efficiency at trolling speeds, and reliability when you’re 100 miles offshore. At Wave Inboard Motors, we’ve managed repowers for some of the most respected names in sportfishing, and we understand that every decision impacts your competitive edge.

Why Sportfish Repowers Demand Specialized Expertise

• Quick hole shots to reach fishing grounds faster

• Precise trolling speed control for optimal bait presentation

• Extended range for reaching distant canyons and banks

• Quiet operation to avoid spooking fish
