Ct Boat has teamed up with Jasper Marine.

When you buy a remanufactured marine engine from JASPER MARINE, you will discover a new source of power from the nation's number one remanufacturer.

Precision machining and quality parts, combined with thorough testing using such procedures as torque plate honing (just like the boys at NASCAR do) and a standard set of new parts like valves, springs, pistons and timing components, and itís easy to see why JASPER MARINE should be your choice for a remanufactured marine engine.

Live-run dynamometer testing and an 18 Month Nationwide Transferable Warranty on complete engines further justify the faith you place in the nations #1 remanufactured marine engines.

Now is the time to buy from us.

Here's why JASPER should be your first choice for a remanufactured marine engine. It's the processes we have developed to instill confidence in every product we make.

Process for Marine Gas Engines

Every engine is completely disassembled. Blocks, heads, connecting rods, crankshafts and camshafts are thoroughly cleaned in the Kolene Salt Bath. Molten industrial salt efficiently and thoroughly removes all contaminants that can result in premature wear to internal engine components and early engine failure.

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 to flushing and brushing out oil passages to remove any contaminants.

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 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 consistancy through Statistical Process Control. 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 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 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 and optimum engine performance.

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 live tests every popular Complete engine with recorded inspections of temperatures, oil pressure, vacuum and compression. JASPER's testing is one of the many ways we assure your satisfaction.

Processes are continually monitored through Statistical Process Control to assure accurate machining, smooth engine performance and complete customer satisfaction.
