biggest gas guzzling outboard
 

I'd say the Johnson V8 briefly produced in the 90's.....or was it the 80's ?

Then maybe the 250 OX66......

Others ?

Yamaha VX250, Johnrude V8, 2thirsty5 johnrude
OX motors aren't that bad compared to these three guzzlers

The BIGGEST guzzler of all was the ever so rare FORUMLA 1 V8's that OMC made for a BRIEF run in the late 80's. I've only seen a few pics of them. The 235 used three 1 3/8" 2 barrel carbs, the FORMULA 1 OMC V8's used EIGHT of them on it, dry exhaust, a removeable exhaust chest, and could turn RPM's in excess 11,000 RPM's.

I'm thinkin 7 marine's 557 could do some serious damage to the wallet

My grand pa has a aging banner that is probably 30 feet wide by 10 feet high in his shop, that has a F1? tunnel hull with one of those Race V-8's on the back. To say it's the most bad *** looking engine is an understatement. It would be awesome if someone made a v-8 2 stroke again that sounded nasty like the old ones.

Johnrude F1 V-8 Wicked and IIRC the big v-8 holds the kilo outboard world record.

You can hear the roar of the fuel going thru the fuel lines. LOL

The Yamaha F350 can really suck down some fuel too. I ran a big Grady White with triples. At WOT it was pulling nearly 100gph between all three.

:oh:

providing 1050 hp at 100 gallons per hour is pretty efficient. HP takes fuel, regardless of whether its 2 stroke, 4 stroke, FI, DFI, or carb. If you want to go fast, its going to cost

But how fast are you going with 1050hp running wot?

It wasn't as fast as you would think. It was a heavy boat. I can't remember how fast exactly. I think low 50's. But the roar of those V-8's really sound great.
