I seem to be a resident expert on OSO about Advantage, but there are a few others on the board that are Advantage dealers, so they may know the speed numbers for you better than I do, and there is a 27 on the board, Chris Gibbons, he has a 2001 27 and here's I'll try to find a pic of it. Not sure of his motor though. I originally looked at buying a 27, but went for the 32 after all was said and done. Depending on your needs, and the speed you are looking for, and what waters you are going to be using the boat in. I looked at everything in the market, and as far as cockpit and cabin space, advantage has the most in this size, and at a competive price. There are faster hulls, but in 2000 they changed the step design on the 27 and I haven't heard about the speeds with the new bottom. My Uncle is the detroit area Advantage dealer, and we had a f2 99 27 with an HP500 carb, and it ran 77 on gps, and was a comperable ride to most 32's on the market, and I attribute this to a longer running surface or no 2-3 foot cutout on the back for the afterthough swim platform of most manufacturers, making your 27' boat, more like a 24 and that makes a big difference in the ride of a boat. If you are considering odrering it, which I recommend, either thru the factory or a local dealer, contact me, there are a few things, which I would recommend changing, but real minor, and at no cost, as they are building the boat fully customized for you already, changing things is no big deal for them. The "in the mold" gel coat graphics are killer, and you get to make it look any way you want it to look, and match the cockpit, and interior to all your custom upholstery choices and all at no additional cost. All aroud Advantage put out a great boat. Spacious, great ride, good speeds out of the hulls, and a fit and finish, at the very top of the scale, and total customization inside and out at no additional cost, and it's awesome watching what you came up with get put down on paper, then made to be all yours. I've helped out about 15 people with thier orders, most locally, but a few oso people have called me and gotten my opinions on what to do with thier order, and how far to go with the customization, and personally, I cant wait to order my next Advantage. Here's a pic of my 32.
