Student at UCF builds 600+ HP outboard motor

This is awesome. I love people tinkering and messing with stuff to make it faster. I wonder what the weak link is now. I'd assume the LU. Rods maybe?

i don,t need a job at Boeing i need one at mercury with an unlimited credit card!
think i mentioned something like that to somebody!

Actually on more than one occasion ...

A job at Boeing might not be so bad right about now. They've goobered the place up. They need someone to get em back in line .. prob get whatever ya ask em for .. Just to show up ..

Merc's got plenty of collage boy teams .. so they won't need any individual "free thinkers" .. They only give Platinum Visa's to the upper sales managers ..
The sharpshooters that go fix the problems that the dealers can't figure out .. get a gas card and maybe enough to take an irate customer to lunch ..

From the link... "The fastest outboard engine on the market produces 627 horsepower but weighs twice as much"
I have to assume this is referring to 7 Marine. Since when did that become the fastest OB? Do the millennial's not know the difference between "fastest" or "produces the most horsepower"
Other than that great kid!

They were talking to a local news station, so #1 they were prob a bit nervous and #2 they were using generic terms that the masses can comprehend ...

Now as far as 600 HP goes .. The dyno I use to flog my big blocks on, had a little cartoon taped to the door. It was a guy throwing up in a garbage can , saying : I just got my new dyno sheet ...
I know they had to say something. But in the real world ... Guys that spit numbers out of their *** are just the ones that the little cartoon guy represents..

I've had my fair share of Honda's . Wrung em out till the needle was facing "nipon-seki" and I can't remember breaking one of em. Those were all bike though. The kids I always saw at the track with those CVCC's or whatever they were .. they didn't do them things no favors either.
Don't know how much Soichiro Honda's personal values were employed in building the outboard motor part of the company .. but if it's like the bikes and cars .. it should be pretty indestructible ..

Chaz= thinkin, Them boys better start whittlin an adapter to put a 1.62 sporty under that thing, ifin they wanna be the "fastest"

this Honda jet-ski 1200cc engine was put together by the owner of http://www.appracingengines.com/
the stock Honda parts seem to be pretty good
off course now his water-pump can,t handle the power and cavitates

I believe you'll see a V-4 four-stroke 3.0L Mercury in that same configuration pretty soon ... Just_ _ sayin ...

turbo on top with a chimney...lol
My money would be on a geared paxton sitting on the crank up top

then the bigger ones will all need to be 2 speed duoprops
( Merc has been there before)

A cvt woud be a great addition providing they can built them strong enough

For inboard engines they could use multiple inline and use oil pressure to engage them so that the friction would always be equal among them

What happens when you leap in and out of the water?

I don't get paid to know that!
Did i mention that unlimited creditcard!?

Ronnie, put away the credit card .. this one's easy ..


Power, ole boy ....
As you can see they are RPM and load sensitive. When the driver burped the throttle past the stripe, the driven stayed engaged until speed was reduced.
Last time I checked, air was thinner than water. So unless your "hang time" is that of Evel Knievel, the inertia of the prop will keep the driven engaged. And the drive will be in the correct spot ( engine rpm) when you stab the gas again ...
Then depending on how much momentum you lost .. the unit would self adjust to be in the right gear at the right time ... make sense

[PanRonnie]

surely if they can build rubber tank tracks they can build a rubber V belt strong enough for a decent amount of time

[PanRonnie]

also a fun one
why stop there and not drill a hole in the skeg bottom to point torpedo ( skeg thickness might need some beefing up )
then drill horizontal holes in the leading edge of the skeg!?
off course going to need a good quality material gearcase ( tinanium? )

when you pull the throttle back wont it go to low gear in the air with no load?

There is a spring in the driven clutch that forces the sheves back together (downshift) when the primary clutch releases grip. The primary also has a spring that helps control the stall speed (engagement) and claps rate. There are a lot of cars using CVT set ups, all of the side by side atvs, and snowmobiles. The clutch efficiency and belt technology has come a long ways in recent years as four stroke turbos have become mainstream.

so not designed for race boats yet as its a load sensing device, maybe good on a ski boat.
I think big outboards are just holding off on 2 speed's

This kid deserves nothing but props. Good ****.
