BMW's new marine diesels

[Anonymous]

YANMAR CO LTD and BMW AG, German manufacturer of luxury vehicles, have agreed that BMW will supply four and six cylinder Diesel engines designed for high performance use to YANMAR MARINE INTERNATIONAL BV as the base engine for the new YANMAR MARINE product line.

This agreement enables YANMAR to have the most advanced marine engines for its product range. Customers will be in the position to benefit from the joint efforts of two of the most reputable companies in their respective fields of operation with a product that will set new standards in the Marine industry.

YANMAR is aiming to introduce this new fully electronic range of Premium Marine Diesel Engines in the market around mid-2006.

Yanmar Marine is introducing four engines in its new-generation BY series, developed under a very close working relationship with luxury car manufacturer BMW.

The company says that the combined technologies of these two market leaders should set new standards for high performance marine engines and significantly widen the propulsion package choice for boat builders and their customers.

These are four-cylinder diesels at 150MHP (110kW) and 180MHP (132kW), plus six-cylinder models at 220 MHP (162kW) and 260 MHP (191kW), rated speed 4,000 rpm. The engines will be available for both shaftdrives and sterndrives.

At two litres and three litres, they are lighter, more compact and cleaner than the models they replace. The engine dry weights are 250kg and 310kg respectively. Length (with gear – to output flange) by width by height of the 180 MHP 4BY180 is 882x758x740 and the 260 MHP 6BY260 is 1151x758x740. All of the engines in the range meet the new EPA Tier 2 and European RCD emissions regulations.

These Yanmar diesels are similar in weight to petrol engines of equivalent capacity, and produce a similar rate of acceleration.

Electronic control is by second-generation common rail with magnetic injectors and the engines include a CAN bus system with NMEA 2000 protocol.

They are turbocharged and intercooled. The turbocharger on the inboard four-cylinder and all the six-cylinder models is wastegated.

The four engines are available with the latest Kanzaki marine gears or a choice of Bravo One, Two or Three sterndrives, developed specially for diesels.

The BY series is due to go into full production early summer 2006.

Jeez! Coming from a BMW heritage, I'll bet those puppies'll take a bite out of your wallet.

Comparison (dimensions with transmissions):

180 HP = 34.7"L x 29.9"W x 29.1"H, 550 lbs. (weight without trans?)

260 HP = 45.4"L x 29.9"W x 29.1"H, 680 lbs. (weight without trans?)

330 HP, Crusader 5.7L = 51.4"L x 28.1"W x 28.6"H, 950 lbs. ( weight with 1:1 B/W trans.)

If I ever get rich I'd like to try on of those 180's in my 22! (A 260 might be a bit much)
