BWM diesel engines

Hi Andy...we are thinking of making a modern version of the "Deep Sea" with our own BWM engines...

Yeah, one with a 100hp Diesel boxer engine you feature on your website will do.

Those diesel engines look like a real good package are there any more details available as the Web site is fairly vague what drive arrangement & what base engine are they etc?

You lads wouldn't be trying to talk poor andymr into a position where he would get nobbled for trade membership, would you? His kind assistance to our new Frawnsch member has been noted, but he's running on fumes now...

Do not want to get into to trouble from the greater good but I think (from Google) we are the only Rib company producing our own Ribs and engines - fed up with people telling us that our Volvo, Mercury or Yamaha engine has problems and it is our fault...anyway hope you are all working hard to get onto the water...looking forward to the warmer weather...?

OK, this sounds interesting. Interesting enough that I'll give you a free hit so you can tell us more about your engines.

It's unusual and sounds like quite a risky undertaking, but it must be an exciting prospect and you've obviously thought it through so what's the deal? What engines have you got? Are you buying in the blocks and marinising them in house? What drives are you using? Will you only be selling them packaged with your boats? Why are they better than the competition?

Not to mention what fuel can you run them on. I'd think there would be value in recycling chip oil if the engine could take it...

Seconded-I'm intrigued.

Those are exactly the questions I wanted to ask & I think a british manufacturer embarking on such an epic possibly market changing adventure deserves some forum leeway
Thank you john Kennet for seeing the sense in allowing the thread to continue ☺

Come on then Andymr were all waiting in suspense to hear about theses diesels your developing
The mods have given you the green light !😉

He's not been online since his last.

However, I've worked out what it is (and who builds it).
It's a 2 stroke,4 cylinder opposed piston twin crank unit with a chain driven centre shaft.

Those aren't cylinders on a boxer motor you can see, they're crank covers.

Let's see who gets it

Probably an aircraft engine derivative...
Lightweight OP engines have been around for quite some time and have been used in small aircraft since WW2..... ( not to mention a myriad of other applications, ie: trucks, trains, ships etc.)

AndyMr, some of us on here are genuinely interested to hear about the engines, so please post.

I can see how it works from your info certainly sounds interesting & an excellent set up if it can be made to work in the boat environment which is different to a plane but quite similar too

If it's an aero engine reliability has to be good but maintenance might be higher & cost might be an issue

I'm assuming the cylinders lie above & below each other with a crank & head at each end
We definitely need more input from the manufacturer

andymr · 24 February 2015, 10:03

Sorry you guys I have been leaving early and getting back late (so I am not ignoring you)
Okay we are producing 3 types of engines all our design and produced by ourselves.
The diesel is a "2 cylinder opposed piston engine" gear driven with a supercharger (but we are testing it with a turbo also) - boy, this is a quick engine (better that a petrol 4 stroke) the other engines are a 3 cylinder "in line" conventional engine but also lightweight and the final version is a V6 petrol 250hp - 400hp that should come out at around 120 - 130kgs...
We are producing the engines in the UK (everything) and for our own products but as production is ramped up (later this year) they can be made available to others?
Hope this helps?

beamishken · 24 February 2015, 21:59

That's a big undertaking for one small manufacturer to develop 3 types of new technology engines using different fuels at the same time do you have any units up & running or any pics or video at present ?
How are you going with certification etc

Nos4r2 · 24 February 2015, 22:53

What's the connection with this?

Weslake - Pully/Ring Gear Carrier

Certainly looks like the picture on the bwm Web site
Looking at the west lake website it's a long way from market yet!

That's where I'm confused-it's apparently been on the BWM website a lot longer than the Weslake website. As an aero engine it'd need certifying though, which us lowly water dwelling mortals don't need on account of most of us (Matt H not included

)not falling out of the sky when our engines die.

It is the same motor. Weslake are a long established engineering company who build their own motors and motors for other people-though who's building for who isn't exactly clear here.

When you look at the westlake website they do have history in engine building & I'd guess it is them doing the development. I'd expect the aero market to be very expensive & possibly a more lucrative market to explore for them than the marine market
My question about certification was referring to CE & emissions both of which a marine engine will need before market
I'd imagine if they can get certification to fit the engine in a plane then a boat would be fairly easy
Still lots of questions to be answered !
