    Your boats might be rather large for the exercise but a simple tow rope and scale will work for most folks.

    Out fishing one day and the operator got too friskey with the throttle in an attempt to get back to a pot line.

    Spun the prop clean OFF ,

    the AMAZING thing was his kid came out and towed us in, with BOTH boats (45ft) on the plane!

    Talk about oversized engines!

    Steyr/BMW

    Well, reading the press release over again, they seem to be saying that the "BMW" diesel engine is actually built by Steyr, which company is actually owned by BMW? Makes sense. As I mentioned in a previous post, "BMW" labeled boat diesels back in the '80's were Steyrs. Whether BMW owned them then, or owns them now, I don't know.
    But at this site:

    http://www.x-raid.de/index.php?id=59

    BMW’s Engine Plant in Steyr has been an elementary part of the BMW Group’sworldwide production network since 1979. Forming the largest engine plant withinthe Group, Steyr is also the worldwide competence centre responsible for thedevelopment of all BMW diesel engines. The ground was broken for BMW’s Steyr Plant in UpperAustria in 1979. Engine production then started in1982, and today more than half of all BMW engines arebuilt in Steyr. The Steyr Plant builds four- and six-cylinderdiesel engines as well as six-cylinder petrol power unit

    So, it looks like BMW and Steyr is one. Does this make sense? Sure. Do I like BMW stuff? Well...I have to admit that I always like Mercedes machnes better.

    A step up from Toyota? well...probably lighter, quieter, smoother. Possibly also more expensive out of the box, and for overhauls.

    I was referring to the relationship developing between Yanmar and the BMW more than the relationship of Steyr and BMW

    According to a couple people I knew who worked for BMW in their short-lived boat foray, they got burned at it, and resolved to stick to their knitting from there forward. So they didn't build boat engines or trucks or aircraft engines or turbines or bulldozers or any of that cool stuff. Just cars.
    Now here comes Yanmar, wanting to buy engines, and apparently BMW is selling them.
    Historically, what does that mean? If you took the example of John Deere/Lugger, or Perkins/Westerbeke, you might say it doesn't mean much. Yanmar will figure out the details of marinizing the engine, and then BMW will say thank you very much, plaster their sticker on them, and they'll be in business.
    Or perhaps the deal will be like GM/Mercruiser, where the two grew closer over time. Mercruiser quit building its own 470 engine, quit using Fords, didn't it? And for their part, I don't know if it's true, but I was once told that the engines for the biggest-horsepower bigblock Corvettes were actually bolted up by Mercruiser.
    Right now BMW seems to be in quite deep with their investment in VW, and they're probably going to be concentrated on that.
    It would make sense that a car maker with all their dealerships and distribution networks could see, supply, and service boats like crazy. And they've tried it. Dodge Watercar, Chrysler boats and outboard motors, Crosley motors, Chrysler motors (remember the Golden Lion? beautiful sounding exhaust), Volvo I/O's. Funny thing is, for some reason it never seemed to work out that the car dealership got into selling motors or stocking parts. Why? dunno.

    6 cyl engine

    I was told that the 6 cyl inline engine was the most naturally balanced configuration of all the internal combustion engines??...and certainly BMW has to be one of the foremost builders of inline 6's.

    So if I were seeking out a good 6 cyl source for a certain displacement engine line, they would have to be at the top of the list, and if they were willing to build some for me.

    Hopefully an automobile engine builder would not be so misguilded to enter the miniscule boat market themselves

    Its 3 cylinders that work very well together so a 6 or 12 works even better.

    As the Air Police seem intent on using downtown LA as a world goal , we will be having fewer and fewer engine Mfg as time goes by.

    Unfortuniatly for Diesel marinizers the newest truck units use 15% MORE fuel since the exhaust MUST be cleaner than the inlet air in some locations.

    Cat , Cummins, Kennworth have had huge layoffs as the big truck companies plan on running "old stuff" as long as there are parts to be had,"Forever " if they can.
