Most boaters know that pitch and diameter matter, but there are a few lesser-known factors that can make a big difference in how your boat performs. These are the things we see every day in the shop that are often overlooked. Your Engine’s RPM Range Matters More Than Speed Many boat owners focus on top speed, but your engine is designed to run within a specific wide open throttle RPM range. If your prop is too aggressive, your engine may never reach that range, which puts extra strain on …

Garmin makes everything from basic fishfinders to complete marine electronics systems with chartplotters, radar, sonar, autopilot, trolling motors, and engine data. The hard part isn't finding Garmin equipment. It's figuring out which pieces actually make sense for your boat. Before choosing a display based on screen size or price, start with how you use the boat. A flats boat fishing Tampa Bay needs a very different setup than a center console regularly running offshore. What Are Garmin Marine …

Outboard engine hours are one of the most common indicators used to evaluate condition, reliability, and long term value. For boat owners and buyers, understanding how engine hours relate to performance and lifespan is essential when maintaining or assessing an outboard. Modern outboards, including those from Mercury Marine, are designed for durability and can deliver thousands of hours of operation when properly maintained. However, engine hours alone do not determine overall condition. Outboar …

Two boat propellers can have the same diameter, the same pitch, and even the same number of blades, yet perform noticeably differently on the same boat. That's because boat propeller performance depends on much more than the numbers stamped on the hub. Rake, cup, blade area, blade shape, barrel design, and other details influence how effectively a propeller grabs the water and transfers engine power into acceleration, lift, speed, and handling. If you're still learning the basics of propeller pi …

SAE 90 vs 80W 90 Marine Gear Lube SAE 90 and 80W 90 marine gear lubes can have similar viscosity at operating temperature, but they are not always interchangeable. The correct choice depends on the lower unit design, manufacturer guidance, and whether the oil is specifically formulated for marine use. Lower units operate in harsh conditions. They are submerged, exposed to water intrusion risk, and experience high load at low speeds. Using the wrong gear lube can lead to accelerated wear, corrosi …
