Mercury V-6's horsepower - Bridgeport ?

US1 heres a good question for you
IM not being a wise guy !

The Carbed Bridgeport had a 5 peddle front half on it
the EFI had its obvious 7 peddle front
you said that they both dyno about the same ....240hp@7500rpm

What do you think a Carbed Bridge port would Dyno with an old 225 7 ped front half?

I think that your answer will be, that a 2 Bridgeports with the same port height... will dyno @240hp @ 7500 rpm regardless of front half.

But i am curious to here if you did it and what your results were...Jay

They will dyno the same. We are only turning them at 7500. A 5 petal will make even more power than the 7 at lower RPMs. Once ported and turned at 9000 plus the 7 petal will do better than the 5. The European 5 petal carb makes 252 HP at 7500.

Thanks, you guys really know your stuff, I moved my engine up 2 more holes and wow what a difference, water presure is still good and this motor really comes alive at 7K rpm. -shane

Should my engine be oily? my old outboards always were but they were carbed and dumped gas out of the intake when tilted. I see pics of other EFI motors on here and they are all clean and dry, mine is always oily and I wasn't sure if that was normal. -shane

I've got a 2.0l blkmax and a 2.4l blk max they get oily, dirty and etc. Nothing a little T.L.C. can take care of (old toooothy brush @ your favorite (chemical /and or beverage) clean nicely. Everytime I see a blkmax I want to get/buy/etc. luv em (don't even care what year model) BLACK MAX I'm glad there were (black) spare parts and motors hide well in dark places /out of the wife's view ! (Told I had too many boats) Ha ! glad she hasn't seen the motas !!

Buy and Hide as many as you can find...... The new motors can't be modd ..... as per se EPA.

Let em leek a bit of oil and run them hard.

That doesn't last for long. Believe me, I know.
Now I have a Bridgeport instead of a wife.

Get a girlfreind......... with a big yard.

Just never let them know how much they really cost. She thinks one cost $500 or $600 like a Chevy 350 rebuild at Kragen. She wouldn’t believe what they really cost anyway. I don’t even believe it.

The first Black Max was 150hp, the 1750(175hp) came one or two years later.

**pyro** · 08-10-2006, 01:05 PM

Are you sure about that?

I thought they released the 2.0 1750 while they still built the inline 1500 for another year. They never made an I6 and a V6, (or an I6 and an I4) at the same time that were the same HP.

Note the 1750 in the foreground, the only V6, and the 1500 and 1500 XS in the background.
