Remanufacturing Procedures

Remanufactured Powerheads

Cleaning
Every powerhead is completely disassembled. Blocks, heads, connecting rods, and crankshafts are thoroughly cleaned to efficiently and thoroughly remove all contaminants, which can result in premature wear to internal engine components and early engine failure.

Cylinders
Cylinders are honed and bored to OEM specifications. The head to block mating surface is thoroughly inspected and resurfaced as required, providing the correct surface finish for updated gasket materials.

Connecting Rods
Connecting rods are machined and gauged to within a half-thousandth for improved operation. Rods are carefully machined to avoid taper and to the standard diameter of OEM specifications.

Crankshafts
Crankshafts are first thoroughly cleaned, then precision machined to exact tolerances. All crankshafts which do not meet factory tolerances are discarded and new ones are used. All thrust surfaces are inspected and machined to provide a precise finish for reduced bearing wear and precise engine operation.

Heads
Every head is resurfaced to exact dimensional tolerances and the surface finish is carefully monitored for proper sealing with the block.

Assembly
Every engine is precisely assembled by trained 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.

Remanufactured Lower Units

Cleaning
Meticulous cleaning procedures remove all contaminants to avoid subsequent bearing damage or failure.

Quality & Precision
All procedures are done to exacting OEM specifications. We replace 99% of the parts with new parts regardless of their condition.

  • Visual and Magna-flux inspections to housings for cracks, wear and stress.
  • Housings not meeting manufacturer standards and tolerances are replaced.
  • Inspection of all bearing and seal surfaces.
  • All bearing and preload tolerances are inspected to meet manufacturer specifications.
  • Standard new parts include gears, driveshafts, propshafts, yokes, u-joints, impeller, upper water pump housing, bearings, gaskets and seals. (Water pump components are replaced as applicable to unit design.)
  • Outboard and sterndrive lower units do not include a water pump. If you need one, ask us and one can be included for roughly $50. OMC mechanical shift and Cobra sterndrives do include the water pump in the upper housing.

OBR builds every gearcase to our exacting specifications. They are the largest remanufacturer in the nation and do nothing but remanufacture powerheads, sterndrives and lower units. All gearcases carry Crowley Marine’s industry leading 12 month warranty.
