Our Remanufactured Engines

With our 40 years in the engine business we have learned over years what parts and processes work the most effectively to produce a quality unit. With that information we have a Premiere Multi-Step Method that we use to remanufacture our engines.

Only the Best Blocks:

We start by selecting only the "healthiest" blocks. No cracks, no rust, no signs of abuse, no signs of salt water use.
We completely disassemble the blocks and vigorously clean them along with the cylinder heads and crankshafts. We use a thermal cleaning process which includes baking them in an oven to remove core material and running them through a stainless steel shot machine to clean them to machinable metal.
