2 Stage Aluminum Sea Pump wit h1 Groove Pulley, 1-1/4” NPT Center Inlet/Outlet

The dual stage Extreme Sea Pump is the next step in our line of high performance, high volume raw water pumps. Incorporating two individual impellers this pump will double the volume of water delivered to your engine or give you the choice of separate routing to individual engine components. Dual stage pumps are commonly found on high horsepower pleasure boat applications where a dual independent water pump for an an intercooler, exhaust system or oil coolers is advantageous.

Available in either: Billet Aluminum or Stainless Steel, this dual stage sea pump is the key to solving over heating problems.

GLM’S EXCLUSIVE MARINE PISTONS
• Fully Machined Hypereutectic Pistons
• Featuring a Hard Anodizing Coating on Top

• Hardness: HV280-400
• Pistons are T-6 Heat Treated

Loopcharged: In 1976 Mercury / Mariner /Force introduced a V6 engine with loopcharged pistons. This engine was the V-175 HP 6-Cylinder. A loopcharged engine has a transfer port cast into the cylinder wall in such a way that it will direct the air / fuel mixture towards the combustion chamber and spark plug tip without the need for a piston deflector. All engines with a flat top or a slight dome on the top of the pistons will be loopcharged. Loopcharged engines will not have removable transfer port covers on the side of the cylinders.
