Cooling System – Sea water heat exchanger cooling system,

Raw Water-Cooling Systems

Raw (Sea) water cooling systems draw water outside the boat (seawater or lake water). Water is pumped from the source to engine block then the engine circulation pump forces the raw water go through the engine block and expelled through exhaust manifold. Raw water-cooling systems are relatively simple as the standard cooling system on most Marine Engines. Raw water pump in most cases is inside the outdrive.

For larger power and inboard engines, the raw water pump is located inside the boat and driven by v-belt or directly off from the crankshaft. The danger is using salt water cooling in your engine, it can be highly corrosive. Running salt water go through your engine block and exhaust manifolds will lead to destructive corrosion, which is unseen until your engine or exhaust manifolds fails.

Generally speaking, marine engines cooled with raw water, especially salt water, has a shorter operation life compared marine engines cooled with a closed cooling system.

Air Intake System – New Walker air filter significantly reduces noise.

Exhaust System – Cast water cooled exhaust manifold for lower surface temperatures, safety and improved performance.

Electronics – 12v and 24v Quantum System electronics feature a proven ECM to monitor operating parameters such as fuel consumption, duty cycle, engine load and speed, while providing diagnostics, prognostics and complete engine protection. Simplified electrical customer interface box for all vessel connections to reduce installation complexity.

Certifications – Complies with U.S. EPA Tier 3 emissions regulations without the use of aftertreatment. Designed to meet the International Association of Classification Societies (IACS) and SOLAS requirements. Consult your local Cummins professional for a complete listing of available class approvals.
