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.
