Marine Engines

(Inboard and I/O)

Head Surfaces

All surface finishes are machined and inspected to ensure proper gasket seating.

Crankshafts

Crankshafts are precisely machined to dimensional and finish specifications for optimum performance.

Camshafts

Added machining improves lifter rotation and reduces camshaft wear. Cast iron camshafts are Parkerized, a process that promotes superior oil adhesion.

Timing Components

Most marine applications will include the correct marine-style oil pan and timing cover.

Valves

100% NEW valves and keepers ensure long-term durability and performance.

Pistons

100% NEW pistons are installed for the best performance and reliability.

Cylinders

Cylinders are bored and honed to OEM dimensional and finish specifications for smooth piston travel and optimum sealing.

Live-Run Testing

Popular Complete engines are live-run tested for performance reliability.

Sterndrives &

Outboard Lower Units

Thorough Inspection

The shafts and clutch are carefully inspected to ensure performance reliability. All tolerances are checked for smooth, accurate unit operation.

New U-Joints

All U-joints are replaced with 100% NEW, quality parts for smooth and quiet operation.

Gears

All gears are carefully examined to ensure they meet or exceed the quality requirements of the original manufacturer and Jasper Marine.

Wear Inspection

All parts are meticulously inspected for wear, and correct tolerances, to ensure long product life.

Paint Protection

A durable nine-step, oven-baked paint process protects your drive or lower unit from the elements and keeps it looking pristine.

Every Jasper Marine remanufactured Sterndrive and Outboard Lower Unit receives (where applicable) all NEW bearings, gaskets, U-joints, seals, upper water pump housing, and water pump impeller to ensure the performance reliability of your drive. (Because the upper drive shaft is not included on Evinrude and Johnson units, water pumps are not provided on these applications.)
