What a Dealership Gives You
01

03
Correct specification
We size and configure the engine to the hull, gearbox and duty cycle before anyone commits to an order.
04
One team, whole life
The people who quote the repower are the people who install it and service it at 250 hours. Nothing gets handed off.
Talk to a Marine Diesel Specialist.
Tell us the vessel and what you're trying to achieve. We'll recommend the right engine and quote the install properly, not a horsepower number off a chart.
