Grooms Genuine Remanufactured Marine Engines
Did you know there really are differences between a car engine and a
Well if you think that they are the same you need to read on.
Marine engines are constantly under a load. It is like pulling a
trailer uphill all of the time. To do this a marine engine must
be built to exacting standards. The clearances for oil and water
must be tight and clean. The cylinders must share the same bore
size for balance. The heads must allow the engine to breath.
Gasket surfaces must be true to allow proper sealing. The best
quality parts must be used on assembly. All parts must be proven
for severe duty to withstand the pain. If any one of these parts
or processes are not performed exact the entire package will suffer
and fail. The parts must all work together. The cam must
produce torque at a low rpm to allow you to get on plane. The
rods must be heavy duty and able to withstand the pounding of
combustion event after combustion event. In other words a marine
engine does not have any coast time.

that you have made the right choice.

straightness and then shot peened for strength, cranks are polished
and trued, cams are either new or reground for the exact marine specs
