Going from Mercury to Yamaha

I would love to have added more power but older boats are not rated for it. I assume that means newer transoms are stronger. Then you have it issue of insurance if you overpower a boat.

Buy Mercury if you want to go fast.

Buy Suzuki if you are short on cash.

Buy Yamaha if you have anxiety about the engine starting 50 miles offshore.

Repowering a fishing boat typically involves replacing the old engine(s) with new ones or upgrading to more powerful or efficient engines. Here’s a general guide to repowering a fishing boat:

1. Assess Your Needs: Determine why you want to repower your boat. Is the current engine unreliable, underpowered, or inefficient? Do you want to improve speed, fuel efficiency, or overall performance?
2. Research Options: Research different types and brands of marine engines that are suitable for your boat size, weight, and intended use. Consider factors such as horsepower, fuel type (gasoline or diesel), technology (e.g., 2-stroke vs. 4-stroke, direct injection), and maintenance requirements.
3. Consult Professionals: If you’re not experienced with marine engines, consider consulting with a marine mechanic or boat dealer. They can provide valuable advice on engine selection, compatibility, and installation.
4. Measure and Assess Fitment: Ensure that the new engine(s) will fit properly in your boat’s engine compartment. Measure the dimensions of the existing engine(s) and compare them to the dimensions of the new engine(s). Consider any modifications that may be necessary to accommodate the new engine(s).
5. Budget Considerations: Repowering can be a significant investment, so establish a budget for the project. Factor in the cost of the new engine(s), installation labor, any required modifications, and additional accessories or components (e.g., controls, gauges, propellers).
6. Purchase and Install: Once you’ve chosen the right engine(s) for your boat and budget, purchase them from a reputable dealer or manufacturer. If you’re not installing the engine(s) yourself, hire a qualified marine technician or boatyard to handle the installation. Ensure that the installation is done according to manufacturer specifications and industry standards.
7. Test and Tune: After the new engine(s) are installed, perform a thorough test to ensure they are functioning properly. Check for any leaks, abnormal noises, or performance issues. If necessary, tune the engine(s) to optimize performance and fuel efficiency.
8. Maintain Regularly: Regular maintenance is essential to keep your new engine(s) running smoothly and prolong their lifespan. Follow the manufacturer’s recommended maintenance schedule for oil changes, filter replacements, inspections, and other routine tasks.

By following these steps and carefully planning your repowering project, you can upgrade your fishing boat with new engines that improve performance, reliability, and enjoyment on the water.
