"85 V20 Cuddy w/ 300 hp Evinrude V8 Asking $2500

[Striper80]

There's a guy on THT with three Monty motors on the back of his scarab. 430hp a piece.

Yup, quick Ferm what is the fuel burn in minutes? I can't imagine fuel flowing through 3/8" fuel hose fast enough. The fuel hose would need to be ethanol AND vacuum rated.

I doubt that engine only drinks 35/per at wot. I'd guess st least 45-50 per

[smokeonthewater]

well 30 gph would be 1/2 gal per minute and 45 gph would be 3/4 gallon per minute....

at $4/gal you are looking at $2 - $3 per minute

[THEFERMANATOR]

Well the general rule is 1 GPH for roughly every 10HP for a 4 stroke/DFI, and about 1 GPH for every 9HP for a carbed 2 stroke at WOT. Some large engines are more like 1 GPH to 8HP, and when you turn them up the ratio goes down even furthur. If you figure smile per gallons it may be worth it to some, but not me. It hurt bad enough when I dropped the hammer on my 225 on my HYDRA-SPORTS. It drank back 28 GPH at WOT, but she was ported and opened a touch.

Yeh how fast ?

I'm guessing could hit 60 + dropped off a shear cliff of the grand canyon.

That thing has got to porpoise so bad!

I have had both a 250 v8 Johnson and a 235 evinrude ( Two of OMC worst for MPG). Even though the V8 ran dual vro's/ fuel pumps, the 235 drank more fuel a WOT than the V8 did. Believe me that's saying something! But the sound that V8 makes at WOT is awesome

They didn't call it the two thristy five for nothin. I imagine a 300 would probably keep up with it though. The 250 got the small carbs, and smaller porting than the 300 got. But the sound alone is worth it.

Geez - running one of those is like hiring a lawyer who likes to hear himself talk. I'm liking my old 4 cyl Merc 170 I/O better with every post in this thread.
