JASPER® Marine Process
The JASPER® process is thorough and our technicians at Craig Johnson Automotive can install your marine unite with confidence knowing the meticulous steps taken to remove all contaminants, inspect the unit and rebuild it to meet or exceed OEM standards.
THOROUGH CLEANING Every Inboard and I/O engine is completely disassembled and thoroughly cleaned to remove all contaminants that can result in premature wear to internal engine components resulting in early engine failure.
CRANKSHAFTS Crankshafts are precision machined to exact tolerances with no odd size bearings or journals. Thrust surfaces are machined in a two-step process to provide precise surface finishes for smooth engine operation and reduced thrust bearing wear. Every journal is inspected and measured with critical accuracy. After machining, oil holes are chamfered to improve lubrication and every journal polished to a smooth finish for long bearing life. Crankshafts are thoroughly cleaned with special emphasis on flushing and brushing out oil passages to remove any contaminants.
CAMSHAFTS Camshafts are inspected for wear, dimensional accuracy, and gauged for straightness. Camshaft lobes are carefully machined to correct specifications. Each shaft is Parco-Lubricated to improve lubricant adhesion, especially during break-in. Any camshaft not meeting JASPER's exact specifications is replaced.
CYLINDERS Cylinders are bored and honed to exact specifications. Cylinder finish and size are closely monitored to industry surface finish standards as well as for accuracy and consistency. This assures smooth piston travel and engine performance. JASPER® guarantees no odd size cylinders. The block to head mating surface is closely inspected and resurfaced as required to provide the correct surface finish for today's gasket materials.
CONNECTING RODS Connecting rods are machined and gauged to within a half a thousandth for improved operation, especially in today's engines. Rods are carefully machined to avoid taper and to the standard diameter of original equipment. All rods are checked for bend and twist to assure smooth operation.
HEADS Heads are carefully inspected for cracks and flaws through procedures such as magnetic particle inspection. Every head is resurfaced to exact dimensional tolerances and the surface finish is carefully monitored for proper sealing with the block. Valve seats and guides are machined to exact specifications or replaced to assure correct valve alignment and seating for optimum engine performance.
ASSEMBLY Every engine is precisely assembled by trained JASPER® builders. Attention to such details as a final wash of new and machined parts and pre-lubricated camshafts, pistons, and crankshaft journals assures a clean, smooth-running engine that performs to your expectations.

JASPER® Marine Engine Difference: Used vs. Rebuilt & Remanufactured:
USED: Used marine engines are pulled directly from a boat that is being salvaged for its components and parts or from one that is no longer serviceable and will likely not return to the water. Used marine engines may not be so much as surface cleaned. These engines are not disassembled, internally cleaned, or inspected. Used or junkyard engines may have high hours, poor maintenance history, and even unseen damage – a failure waiting to happen.
REBUILT: Rebuilding is to recondition by cleaning, inspecting, and replacing the engine’s severely worn or broken parts. The engine’s serviceable parts are reused within the acceptable wear limits of the manufacturer. Rebuilt component quality can vary widely and many engines come with only a short-term warranty.
REMANUFACTURED: A remanufactured engine is machined and assembled as closely as possible to the measured standards of the original equipment manufacturer. All core material like the head(s) and block castings, crankshaft, camshaft, and rods, are carefully inspected, verified against original equipment measured specifications to assure correct dimensional tolerances, and precisely machined. Replacement parts for a remanufactured engine are new or requalified to meet exacting standards and tolerances. Remanufactured engines are tested for adherence to the measured standards and tolerances of the original production engine.

Outboard Motor Care Tips
Here at Craig Johnson Automotive in Rowland Heights, we treat every boat owner as if they are family and want to help you enjoy your marine unit for many years to come. We know, that keeping your boat in top shape is crucial to keeping your boat in proper running order, so we wanted to share our top tips with you! Preventive boat motor maintenance facilitates safe boating and can keep your motor reliable for a long time. Here is a list of complete boat service and helpful tips for what you should do as general maintenance while using your boat throughout the year:
- Flush out the engine. This doesn't just apply to saltwater adventures, but to freshwater outings as well.
- Startup the engine and let the water pump do the rest (practice safe boating by remembering to stay clear of the prop and make sure no one tries to shift the motor into gear).
- While flushing the motor, we will check the water pump to make sure it has good water flow. This enables us to check the health of your boat’s water pump.
- After flushing the engine, disconnect the fuel line and allow the engine to burn all the fuel in the carburetor. Once you've finished the flushing and run the engine out of fuel, be sure to turn off the key and, if you have a battery switch, turn it off.
- Take the engine cowling off and check for fuel or water leaks. If you find leaks, consult your safe boating mechanic.
- Wipe everything down and spray with an anti-corrosive like WD 40 or Quick-lube. We will also lubricate all the moving parts, such as the shift, throttle cables, carburetor valves, etc.
- Replace the cowling and wipe it down. Keep a canvas or plastic cover on the engine between trips. Always use fresh fuel. At the end of the season, boat motor maintenance should include draining your tanks and taking the fuel to the proper recycling authority.
- Periodically check the fuel line for cracks and worn spots.
- Make sure the fuel primer bulb is not cracked and is pliable.
- Make sure the fuel-line fittings seat properly and don't leak.
- Check the clamps on the fuel line for rust or corrosion.
- Check the fuel tanks for damage and corrosion.
- Check the tank vent to make sure it aspirates properly.
- Check regularly for water in the fuel.
