No turbocharger or supercharger...just a V6 or V8 outboard, four stroke,
300 shp.

My local Yamaha dealer says he thinks in three years or so.

I'm guessing Suzuki.

You'd guess right and I heard form a normally fairly clued in type
that it's next year.

Rumor has it Mercury is working on a 300hp 300XS optimax

Suzuki seems the most adventurous. Doubt I'd buy one, though; the
engines seem ok, but most of the Suzuki dealerships I have seen seem
marginal. The extended warranty Suzuki gives away isn't much good if you
can't find a dealer who handles it properly and on a timely basis.

The Squeezeuki mechanic over in Rhode Island is pretty good actually.
He seems to have a real handle on four stroke outboards.

The word that I heard is that some of the 300 hp tech is coming right
from the motorcycle side of the business - small V-8 producing
horsepower via the high rev route.

Dunno - we'll see.

V8 outboard? sounds crazy having that hang on the transom.

Whats wrong with a light supercharged V6???

I'd guess Suzuki too. Their current engines have the cubic inches to do it
pretty easily.

I prefer the large-displacement, naturally aspirated approach to
horsepower in gasoline engines.

me too, except when it hangs on my transom. Then lighter is better.
which a charged motor will deliver :)


I have a boat large enough and strong enough and heavy enough to handle
a single V8 outboard on the transom. But a 300 hp V6 would interest me.
I've got a 225 now, and it would take a jump to 300 hp to make any real
difference in cruise speed.

I dont know ... I would take light at any boat

You have to remember - these are extremely light, high rev engines
we're discussing here and only in theory. To produce that kind of
horsepower in a light weight engine, you need revs - lots of 'em.

Nothing really - could work, but it's not normally aspirated which I
assume is the goal here.

Again, this is all hear say, nothing actually is proven and it's all
rumor mongering.

Speculation if you will.

not necessarily. A charged motor will have ample torque.

I'm not arguing that - I agree. But with normal fuel injection
breathing normal air, you need high revs.

While others might be, I'm not really concerned about the weight of a
300 hp outboard for my Parker. The 225 I have now weighs 500+, and these
boats are now being sold with two 225s, so that's a half ton on the
transom. The boat is heavy, with a lot of weight amidships and forward.
A 700 pound single outboard on the transom producing 300 hp isn't going
to upset the boat's balance, although I would guess 600 pounds. Half a
tank of fuel on my boat weighs about that.

Good point.

thats true. Not pretty for a boat motor

Suzuki large-displacement DF250: 580 lbs.
Mercury supercharged Verado 250: 649 lbs.

Lighter *is* better!

I'm glad! I have a Douglas Skater and want to upgrade to a newer engine! The
4strokes are just too heavy.

Yes, I heard that, too, but it isn't a four stroke.

I think it's going to be a hot rod version of their present 250 which is a
3l V6.

Take a look at Evinrude E-TEC.

Wave of the future and that sort of thing.

How small? My SUV has a 4.4L engine with 315HP.

No idea - its' all speculation.

5400 RPM's. Torque is 324 l/f @ 3600 RPM's and 32 valve engine.

Seems like the 4.3L V6's could get 300 HP but they were rated around 190.

That's a lotta output for a truck engine; how fast is it spinning to
produce that 315 hp? I think my vehicle's engine is a little larger than
than that, but produces about 80 less hp, or something like that.
