Vote: best brand of inboard propulsion engine...

definately made by yamaha , not yanmar or toyota. rebranding is done with a lot of yamaha stuff. i was also told yamaha make a lot of engines and parts for other companys to.

 

..that's what I meant to say... still hung over

 

One of my mates won a trip to the Yanmar factory ( he is a dealer) he had some photos of the guys preparing bare blocks and grinding the Toyota logo off them.

I agree Yamaha have done lots of contract work for various engine suppliers all over the world that may or not be their designs though.

Just like Selva manufacture all the Yanmar sail and sterndrives
MerCruiser built the Lotus designed 32valve V8 in the Vette a few years ago

Got skill and idle plant you get the job

 

Not having my favorite manufacture above, I haven't voted.

Think hamsters, lots of 'um. Don't laugh yet, I've given this some thought and it may be about the greenest (well, at least brownish/gray and fuzziest) displacement speed propulsion setup available.

Naturally, you'd have to approach it logically, so lets start with an enclosed breeding area, for self sustaining little beasts of burden, maybe an acrylic box or two, so you can see your future fuzzy engines, grow into feisty little slaves. A small PV panel to supply heat and a fan for their growing little bodies.

Next would be the training area and again, acrylic boxes, with little tubes and wheels to keep them entertaining, in good physical shape, as an electrified fence keeps them motivated and on course. Naturally, you'd probably want to shape the fences to keep them going around something, maybe a dog track looking kind of thing, just to spice things up. A miniature, revolving electric bunny would be a nice touch.

Once trained, the new recruits can be introduced to the wheel of death, because lets face it, this is where they're going to toil until dead right? They're just hamsters, so get over it, besides, there's more on the way, remember the breeding boxes you built and they taste good with a little garlic, so consider this recycling.

The wheel should suck about 2/3's a days energy level out the little beauties, just to keep them honest and worth the meager amounts of food you'll have to provide. I hope they like fish, right . . . they'll learn. Say 50 or so hamsters, which is 25 pounds of rodent muscle, walking around a 48" diameter wheel, an appropriate gear setup for torque multiplication, with an eye towards being easy on your tough, but frail little beasts.

I think this is near perpetual motion, especially if they could be trained to fish for their own food too and self season themselves just before they drop dead from exhaustion. You can distil their own pee for their water needs, with supplements from your own pee if necessary, because what are you going to do with it anyway, but waste it.

Come on, being green isn't hard, can offer some friendly companionship (don't get too attached), a tasty supplement to your diet and cost little, once you get a few generations under your belt. Screw that nasty diesel, go green.

 

Is it magic mushroom season already

 

For a 50 ton boat, cummins 855 nta . Only way to go.

 

I do have a gardner 8lxb i could part with.

 

one of my favorites

 

why would you want a cummins when you already have a gardner.

 

Plenty of .af spanners , right out of Whitworth spanners .

 

bingo!
PS plenty of Whitworth tools in Singapore

 

This is a very good point.

 

wow if anybody did that Volvo would never sell another engine

 

wow if anybody did that Volvo would never sell another engine

Volvo sells few engines to consumers , they sell to boat assemblers where the lure of a very low purchase price gets multiple sales.

A knowledgable purchaser would avoid this con , but too many are interested in a low initial sales price .

IF course if first boat purchasers were better informed ALL boats would be FR , fire retardant resin, all would have easily maintainable fuel tanks (not just a box of fuel) and many other long tern problems would never exist.

 

too true FF

How about pod drives, did you read the feedback from Bill Barry Cotter
after 2 years of them I think he wont build a boat with them any more
