At FirstMate Marine, we bore every cylinder to within .004 of the fin- ished size. Then we use a diamond hone to ensure bore geometry is held within 300 millionths of an inch. Next is a surface finish test to measure the roughness and plateau finish of the cylinder wall.
We completely assemble each engine in a clean and controlled environment under the supervision of
a trained Quality Control department. Constant super-vision, testing and auditing assures every FirstMate Marine Engine meets our stringent requirements.
FirstMate Marine Cylin- der Heads are cleaned and re-manufactured to perform like new. Our quality programs en- force excellence in every operation, from hand repair to state-of-the-art 3-angle seat cutting.
