There is something special about when a client takes their newly powered boat out, running it up and having this huge smile, and saying:

“This is the fastest this boat has ever gone!”

Complete Amsoil treatment throughout – Amsoil Assembly lube, Amsoil break-in lubrication. Amsoil Signature Series Max-Duty 15w-40 Diesel oil, and Amsoil Filters, to give these engines the best of the best! Even the Coolant is Amsoil’s amazing Low-Toxicity, Bio-degradable coolant with specs even the US Military uses!

Twin Cummins 6BTA5.9’s getting ready to be lifted out for rebuilding after the interior, galley, and seating was removed to gain access.

The Cummins 6BTA5.9 engines do not have replaceable liners like their bigger cousins, so a proper engine rebuild requires services from a professional engine machine shop where the engines are dissembled, measured, and then machined to specifications ensuring a reliable and bullet-proof rebuild.

Once the engines are rebuilt, they will be run up on a dyno for the break-in, as well as to ensure the engines are running at 100% before going back into the ‘hole’. The other benefit to running the engines on the dyno – the team will tweak the engines for maximum fuel efficiency!

Next will be the removal of the engines – stay tuned!!
