has any one tried this before,and with what results thanx for the input

Tried it on mine with 525's, and could not get it to plane, added a 1" spacer and it was much better, still tough to plane with my 5 blade 30 pitch, but worked well with the 32 bravo.

thanx for the reply, i think i will stay with stock and add some nose cones

Keep us posted

Ha nordicflame, how does your flame handle with the power you have

The fastest Flame that I know of did 115.8 mph. It was in a magazine article doing 112+ mph. The guys name is Terry, and he lives here in Seattle.

They tried several different length lowers, and ended up using 1 inch shorties.

John at Eastside Offshore (the guy who set up the boat) said that the 1 inch shorties were the fastest and handled the best. When they tried going to a 2 inch shortie, they almost rolled the boat several times at over 100 mph. The 2 inch shortie combo was unstable.

Terry sold this boat, and now has an Outerlimits v-hull that does over 140 mph.

Fine until it gets right to near 90 then she starts rolling back and forth.
I have switched out my 280 K-Planes for 380s but haven't tried them yet. This was per Tres Martin's suggestion as he does a lot of work directly with Nordic and has good success with this move.

I'll be curious how the nose cones work as I can't afford 1" shortys

Great info Chris... Thanks

Dave,

According to John, The 1" shorties really helped with the rocking, but it was blueprinting the last 5 ft of the hull that made it stable over 100 mph. Especially sharpening the edge where the hull meets the transom.

After the adding the spacer to make it only one inch shorter the boat handled much better than stock. I used to get that white knuckle ride starting around 86 mph. The boat would become very unstable.
Now the boat is much more stable all the way up to the top speed 91-92 mph.
Don't know if it was from switching to the shorter drive, or having the cones on the drive that did it, but it is much more fun to drive.
