Hello guys.... I have a 2000 47 with 500EFI's and am considering changing to larger twin power with Merc 6 drives. What are your thoughts? I would be going for something from 800hp to 1000hp each...

I would not be installing these staggered... they would be side by side and I'd plug the center hole from the stock bravo drive.

I am thinking about resale value along with everything else... Would it go up with solid twins or down?? What do you guys think?? Is it better to just stick with stock power or move to something bigger in a twin configuration?

thanks in advance!!

My personal opinion is it would decrease the value to just pull one engine and leave it a side by side. I don’t think you will recoup any cost of major modifications but if you are doing it for yourself because you know the boat that is a different story. I also think large power is a much tougher sale to most people and the 500 EFI is a nice package that I think would be a much more marketable package.
If you keeping it, are going to the trouble to change drives to 6’s with big power you might as well do yourself a favor and do a staggered setup or just leave it alone, JMO.

There's a 47 around here with twin 850's supposedly runs 106. Think about it, you use less gas, have one less engine and drive to maintain along with all the ancillary bs that goes along with it. You also drop the weight of the boat and drag of the extra drive. To me it's a no brainer.

An older gent at my dock on Cumberland spent a fortune re-powering a 2000 era 47. He literally has an open check book and had triple 1100s built and IMCO scx's put in it. After spending a fortune trying to get it to run fast he sold it for next to nothing and bought a new 42 with 1075's.

My last name isn't Fountain but I have been told that the 2007 and newer 47's have great hulls and as Fanatic said can be made to go relatively fast with modest power - because they are staggered! An older 47 with twin side-by-side power is probably going to be a real turd - if not Reggie would have plugged that middle hole years ago and sold the 47's side-by-side from the factory.

To give you an idea of how much the newer hulls and staggering have helped the speed of these boats, my 2000 38 Fever with a set of side by side 710 Ilmors topped out around 95 MPH. The 2007 and newer 38's with better hulls and in staggered configuration are seeing 112+ with 700 hp.

If you want to go fast with reasonable HP you need to have that staggered set up.

To me it's a no-brainer, don't waste your money on a side-by-side set up on an older 47.

Twins with big power - no contest. - (you would have to stagger them or else it would be worthless)

I would agree with the others that if you are going to spend the time and money, staggered twins would be the way to go. However, I do not really think there is going to be much if any weight savings going to twins. If you think about it #6's are heavy, add in transmissions, and blowers and you are probably about the same weight as a third bravo and block would add.

Ok... well it looks like the pole completely slides towards the twins. I should have altered it to say "side by side" big twin power because that really is what I am looking at. Is there anyway possible to use the same stringer configuration with stagger situation?... or are we talking full gut and rebuild?

Also, what is the major difference between a 2007 and 2000 47 hull?? is there that big of a difference?

Thanks guys

In all seriousness, staggered twins.

If you have resale on your mind, then don't touch the boat. It will be next to impossible to sell with mods unless you somehow come out the other end with a conversion that appears stock. To do that you would be spending HUGE money.

Leave it as is, sell it, and buy a newer 47 factory stock with the configuration you want (twins or triples). There are WAY too many newer Fountain's on the secondary market for great money. You will be further ahead of the game.

If you want a lab experiment with your current boat, go for it! But, results will vary and consider it a long term relationship. No one will want it unless you give it away.

I would talk to the gang at FPM. I bet they would tell you just pulling the center and adding power to the other two won't net you any decent results. And I have to beleive handling would be affected.
