Across all machine design seals, the O-ring remains the most common type for a variety of reasons. O-rings are fairly inexpensive to produce, simple to manufacturer, highly reliable, and provide for quick installation. Because of this, the O-ring is used in many different applications and provides for a number of uses. In this blog, we will discuss what O-rings are, some of their various types, and their shelf life.

Before deciding whether or not you need to repair any broken propeller for your boat, it is important to first establish if replacing would be a better option as opposed to doing propeller maintenance work. You can figure this out simply by asking yourself if the propeller kept your motor in the correct rpm range. Did the boat using the propeller accelerate well? Did you notice vibrations from the propellor when taking out the boat? If you answered yes to any of these questions, then a replacement might be better than trying to repair the propeller.

With the advent of lighter, higher RPM engines for marine vessels, engines have faced less ability to absorb vibrations that come with operation. With Marine engine mounts, boats can work to dampen the amount of vibrations caused by the engines, while also ensuring that the engine is secured to the vessel correctly. In this blog, we will discuss the importance of marine engine mounts for vessel engines.

The end of summer marks the close of boating season, so as the days shorten and the nights turn colder, owners of boating vessels take this grace period before the chill fully sets in to prepare their vessels for a long winter. Aside from just simply storing away their boats, there is more that needs to be administered in order to ensure the functionality of a boating vessel for future seasons. Doing less could leave your boat vulnerable to damage and costly repair work.

The motor is obviously one of the most important considerations in a boat’s design, determining the boat’s speed, maneuverability, center of balance, and maintenance needs. There are two choices in where a boat’s motor is placed, either an inboard configuration, or an outboard configuration. In this blog, we will break down the differences between the two designs, and their respective advantages and disadvantages.
