Bullet Prop and Speed thoughts
 

well motors are at buliders Atepco in Waukegan IL
!989 notched bottom Bullet newer bravos
shootin for 575hp I will be at dyno pulls
any thoughts on a good starting point for props
and any guess to top end I an thinking high 70 and maybey 80 with the current
I have 21s 23s and 24s wich will be for sale or trade in about 10 weeks

Hey Klaw.....Same year boat as you......650 hp.....28 Bravos...
Bumping the rev limiters ar 5500rpm {cool weather}....
Depending on the torque you are making you might try 28s...
My blower motors make gobs of torque...I am trying 30s this year.
Hope this helps for comparison.....Paul

what kind of speed are you seeing at 5500rpm
if your 30s work will you want to sell the 28s

I saw 81 {GPS} with the 28,s......I think i will need to keep these
for those hot,humid august days ! It feels like i lose 100 hp on those days !! These things need all the bow lift they can get..
I never even thought to try 3 blades...I have alot more testing to
do when the weather clears up !!!
When do you get the new motors ?

should see them in the Dyno in about 6 weeks have started to tear down and have found a few suprises
the are 1995 gen 5 and there were roller rockers and cams in it I thought this was a tappet motor
the guy I bi\ought them from boughtt fro fountasin new an says they were never opened up
I will talk to him monday
one of thr \e motors was sealed

Hey! my Bullet w/ 496's &250 blowers making around 630 has seen 84 w/ lots of trim!! turning 28 bravos at about 5200. i will try the 27 three blades! also thinking about trying the 2"shorties this summer to see if it will carry it higher w/out the flat water porpoise!!

We have a 1992 w/ 2/750SC. 97 w/ 2" shorties and 30" Bravo's. Shorties gave 5 MPH on this boat. We are adding intercoolers, Dry CMI's and new cams, should make 100+ HP, and boat should run at least 103 MPH. Will post speeds soon.

I think the shorties will solve that problem as the X was conservative on these boats!

I don't know why you guys have so many problems w/ bullets. The 1992 we have was the easiest boat we've ever rerigged to make go fast. We run 2" shorties, 30" Bravo 1 props, 1.5 to1. The boat is easy to drive. My girlfriend can run it 90+. No chine walking, slight porpoise at slow speeds (trim tabs!) Great in rough water, and accelerates better than anything on the water. All this w/ A/C. Feel free to call me with any questions
