Clean-Burning Repower Drives MMA Tug

A NOTEWORTHY repowering project at
Billings Diesel & Marine Service was the Maine Maritime
Academy’s well-known tug Pentagoet. This extensive
job involved replacing two 16V-92 Detroit Diesels
with modern, clean-burning electronically controlled C-
18 Caterpillars. Additionally, we rebuilt the exhaust systems,
replaced both generators, and performed cooling
system upgrades.
While the tug was hauled, our paint shop painted Pentagoet’s
topsides and sandblasted, in an environmentally
sound enclosure, a large portion of the bottom, followed
by the application of an industrial bottom paint system.
The carpentry shop’s contributions included the installation
of the new engine’s control and instrumentation systems.
