Sierra Marine tilt/trim reservoirs are simpler and better to fill when your boat is on a trailer since you can lower the tongue to the ground and get the tilt/trim reservoir as straight up and down as possible. The power trim fluid storage is either a reservoir within the power trim pump or a separate plastic reservoir near the pump. This tilt and trim device allows you to improve your water craft's performance by modifying the angle of the engine, which alters the boat's running surface. Tilt and trim your engine helps the boat's performance in several different situations, from smoothing out a harsh ride in strong waves to lowering draft in shallower waters. Maintaining adequate fluid levels is required for the trim system to function effectively. For quality parts and components to keep your boat on the water and running strong, Sierra Marine has you covered. Order the tilt and trim reservoir model designed for your boat application.

Sierra Marine bellow expander tools aid in the installation of exhaust bellows on MC-I, R-MR, Alpha One, Bravo One and Two, and Blackhawk drive units.

Before anything, you must remove the Sterndrive in order to use this bellow tool. After the Sterndrive has been removed, simply install a bellow on the gimbal housing, and then stretch the bellow though the exhaust hole in the bellhousing, tighten the hose clamp—and voilà—done!
