Wow again, I'd like to see a flatbottom set up for this and bring back the BFF class.

Has already revolutionized the world of Dragboat racing and now will be available to hot lake boats. WOW! The single screw is dinosaur technology! I agree with you Sangerboy, bring on the Blown Fuel Flats . . . sh*t all the flats for that matter. . . they could use this! http://free.***boat.net/ubb/cool.gif

Tiwn props is nothing new. It was done back in the 60's. If webshots will work check out this twin prop flat from 1968. Oh, I got this lil bit of info from 72superlight a long time ago.

OK, lets see if the HB media center works better than webshitz.

I downloaded those articles. Very interesting. Not only does Faulkerson discuss the merits of the twin screw set up but he really explores v-drive placement, shaft angle and push point. He also explains the boats center of gravity vs. it's balance point, effects of rudder drag and angle, etc. A while back there was a thread on motor placement, shaft angle and prop location. There's great info on all of these topics. It's recommended reading...

I am a bit past the 40 milestone and went digging through some old magazines and in the summer 1965 issue of Hot Boat found a blown hydro called El Tigre II that ran a twin prop W-drive type system. The boat was owned by Tom Weeda. These systems were seemingly ahead of their time because improvements in hull design, running gear and handling tweaks let the single prop systems continue to work very well. With the power levels being produced in todays top classes this W-drive seems to be an effective way to put serious power to the water with greatly increased consistancy and safety.
