MAXX, great thread, I check it every once in awhile.
Are you retiring from your current employment?
Looks like you have a gift/talent that many could benifit from.

Speaking of X dem. On my double step Donzi, I am 5" from shaft center to hull bottom, I called IMCO awhile back and they said they could not help me if I was under 7".

We missed you at our party, maybe next time.

Bryan, I will be retiring in a couple of years. Keep me posted on the next gathering. I just finished huge project for a friend that took up most of my spare time these past few months, but I am freed up now Give me a call about the Donzi.

I have a good article about nosecones and why you lose speed when you go from a alpha to a bravo. if you have a fax i can fax it to you

That would be great!!! My fax number is 757-664-6932. Basically I have relying on conjecture and assumptions as reasons why you see minimal gains. Again, thanks

Off the topic the photo you posted looks like the trim tabs hang down at an angle below the the hull. I always belived that when all the way up the should be several degres up to help creat negitive presure like a rocker. You might try taking them off sence it is simple to do for top speed. And with your drive hight I dout you need them to get on a plane? Just a thought. Charlie

I have another article from hot boat mag. about aspect ratio/length by diameter just have to find it. Tommy V we are just trying to help you, tom cat ,cobra marty, kamma are knowlegeable guys just so dont take offence.

454hoho, I got the article. It came through kind of fuzzy, but I was able to get the jist of it. According to the article my, generic, comment about the mass of the Bravo was correct. This article really broke it down to specifics (Budman you may interested in this). For everyones information: the Bravo and Alpha are the same length and have the diameter bullet. Where they differ is the length of the bullet and the size of the case above the bullet. The Bravo, with the larger pinion gear, requires a larger case and this area is responsible for the decreased speed.

454hoho,

Can you fax that article to me? Fax is (502) 339-5399. Shoot me an e-mail when you are getting ready to send it, please.

Thank you very much!

Id like to see that too. Were they refering to the old bravos or the new ones?

I dont have a fax number to sent this to. 6pages. asfor new or old bravo not sure havent reread the article but was written around 2000 and pics show low water pickups
