Jackshaft Power System (JPS)

The performance and fishability of a 30’ plus sportfishing boat... from a 24’ to 26’ trailerable.

With an investment of close to 20 years of rigorous research, unforgiving testing and continuous refinement, Albemarle has succeeded in perfecting a power system that is recognized by both hardcore fishermen and sophisticated boaters as the world’s most efficient propulsion system. Developed in partnership with Volvo Penta, one of the most trusted names in marine power systems,
our Jackshaft Power System (JPS) delivers a number of unique advantages
that make it the clear choice for serious offshore anglers.

Superior Performance

The JPS moves the engines forward in the hull, lowering the boat’s center of gravity and placing its center of buoyancy where it logically belongs – in the center of the boat – giving a significantly more stable and solid ride in rough seas (unlike outboards with several hundred, and in some cases more than a thousand pounds of engines hanging on the back of the boat).

Duo-prop counter-rotating propellers put 60-70% more propeller surface in the water, virtually eliminating cavitation and vastly improving handling and maneuverability in both forward and reverse by eliminating torque steer.

Counter-rotating props also help deliver up to 15% more thrust, 20% better acceleration, and up to 15% better fuel economy.

Unlike the downward angle of a traditional inboard shaft, the sterndrive’s prop shaft is parallel to the water so that it smoothly and efficiently converts engine power into straight-line forward thrust.

Excellent Fishability

When you have hooked the catch of a lifetime, the last thing you need to worry about is trying to fish “around the engines.” Like the cockpits of larger sportfishing boats, the JPS configuration allows for the ultimate in a clean fish-fighting platform – free of obstructions that stand between you and the fish.

The unobstructed transom also affords a substantial fishbox
within easy reach.

With the heavier Carolina hull of an Albemarle, the improved weight distribution of the JPS delivers a stable trolling ride and clean wake, excellent for bait presentation.

The lower center of gravity created by the JPS, combined with the counter-rotating props, also translates into unmatched reverse steering power, control and maneuverability when backing down on fast moving fish.

In comparison to a traditional inboard, the JPS delivers a significantly increased ability to fish and navigate shallow water.

A Long, Low Maintenance Life

Due in large part to its power being derived from a highly dependable V8 engine, the sterndrive offers superior performance and less maintenance than an outboard engine. The big-block engine generates horsepower at a much lower RPM than do outboards, decreasing wear and tear and considerably increasing its life expectancy.

On our 242CC, 268XF and 280XF, the JPS is available with diesel engines, a power system long known for longevity and efficiency.

Getting to the engines for routine maintenance and fluid checks is made simple through large hatches with gas struts. Each opens effortlessly to allow unimpeded access all around the insulation lined engine compartment.

Once an issue, the concern about outdrive corrosion is a thing of the past. Through the use of specially developed alloys, multi-step painting processes, ceramic coatings, and advanced freshwater flushing systems, these outdrives are incredibly well built and carry impressive corrosion warranties from the manufacturers.
