I have a drive shower which scrubbed a little speed, and carry a bunch "stuff" in the cuddy. Prior to the drive shower and all the clutter, I could get about 68 - 70 and it would start to chine walk.

Recommend steering first, then horsepower. My steering sucks compared to what I want. If I did not have to have the engine rebuilt again this summer ( lifter decided to disintegrate), HYD steering was next.

Keep it turn key for a while longer!!

Really? I would have thought it would have more speed then that. Glad I didn't spend the extra money for the blue motor boat I was looking at.

I have a 2000 271 fastech and have done to my boat what you are looking to do to your boat. If you call formula they will tell you not to add anything more that 650 hp to your boat. I took my 500 hp and sold it. I had a 540 built fuel injected naturalyl aspirated. I have dual ram hydraulic steering, added 280 K-Planes, and had my gears in my drive kryo'd by Johh @ the bravo shop. This guy is good. I dyno'ed 647 horsepower @ 5600 with 685 ft lbs. torque. The best I have seen is with three guys and between 1/2 and 3/4 tank of fuel is 76mph. The boat does not chine walk and rides stabil. I would not skip a step if you want those speeds out of a 271. It all needs to be done together to be safe. If you have any questions feel free to contact me and I can help. Good Luck! [email protected]

I have a 2000 271. The current motor is 800hp 540efi. I have not been able to get it out to tune in a new prop yet. When it had a 693hp 540 I could get low eighties GPS full of fuel with 4 people onboard and still some throttle left. My boat has full hydraulic steering and Merc 280s tabs. Bravo XR drive with 1.50 gears. The boat does chine walk pretty good at speeds over 75mph. I would say you need at least 625hp to pull 75mph at any time. Jeff Wurl

Bad monkey please post some pics of your redo would love to see what you have done! just dropped a 496HO in mine

You'll need over 650hp, steering, and a stronger drive. I see low 70's full of fuel and people.

Well maybe you should change your screen name? Fountains are superior rough water boats that still go fast! Simply one of the best handling, safest, fastest speed boats you can buy. A single 525 twin step mid 2000's 29 would be a huge upgrade for him, and he would no longer have a boat that is simply glued together.
