New Navy Patrol Boat and Diesel Outboard

40 PB

Marine Log brings us news of a new Navy Patrol Boat, Autonomous Control, and a new 300 HP V-8 Diesel outboard.

Delivering 300 horsepower at the propeller, the CXO300 is the world’s highest power density diesel outboard engine. The four stroke V8 diesel CXO300 offers up to 25% more range compared to gasoline outboards and is designed to last up to three times longer. The engine combines the simplicity and economy of an outboard installation with greatly improved safety and reliability achieved by eliminating the need for highly volatile gasoline.

This is what I reported about the patrol boat in January 2018

MarineLog reports the award of a contract for up to 50 new 40 foot (12 meter) patrol boats for the Navy.

Subject to annual appropriations, the Navy intends to replace approximately 100 to 160 of its existing 25-foot and 34-foot CRF (Coastal Riverine Forces –Chuck) patrol boats with the larger and more modern PB(X) platform over the next fifteen years.
The Navy has placed an initial, immediate order for eleven of the new vessels. Under the terms of the award, potentially worth over $90 million, Metal Shark will build up to 50 PB(X) vessels for the Navy, along with trailers, spares and training packages, and technical support.

This is what was reported here in February 2017 about the diesel outboard.

MarineLink reports,

“The US Coast Guard has entered into a Cooperative Research and Development Agreement (CRADA) with British diesel engine innovator, Cox Powertrain. The CRADA will evaluate and test the advantages, disadvantages, required technology enhancements, performance, costs and other issues associated with diesel outboard engine technology.

“There a been a big swell of interest in diesel outboards since NATO introduced its single fuel policy, with the military and naval forces of member countries keen to phase out petrol-fuelled outboards in favour of cleaner diesel alternatives.”

Obvious advantages if we do not need to deal with two different fuels, in addition to the additional range advantage. Reading the rest of the post, sounds like this is close to realization.
