1988 formula 29 pc info
 

Does anyone know the wot on a 29pc running 7.4 twin bravos? Has no ac/gen. Props are 16's 4 blade Appollas. Also...does anyone know where to purchase the amber lighted toggle on/off switches? I cant seem to find them. Much help appreciated. Mike (I gave up trying to register to formulaboats.com)

I am thinking about 50 with everything set up optimally. Those are nice boats...I spent a weekend on one years ago and I can tell you they handle rough water very well and have a very functional layout.

Then something wrong, hitting 41 wot at 4600 rpm. Bow does seem low. Planes nice without tabs. Maybe bravo1 a better choice? What size people running?

That is about right for the boat speed wise Dtile and you are in the HP range. If you want a little more speed (assuming you are working with twin B2s) you can grab a pair of the 3 blade elephant ear props from Merc. With your boat you prob do not need twin 4 bladers.

Email Steve btw to get that forum issue figured out.

The four blade may be pushing the bow down and creating drag. I would try Mirage or Mirage Plus. Formulas like to get up on top with the bow up a bit to run their best.

Those boats typically have odd gear ratio bravo 2's. a much larger diameter prop setup. Mirage pla isn't going to work to well I don't think. The stock merc 3 blades work well or swap to bravo 3's.

The b1's are 1:50 and counterotate in. Just think 16s are a strange pitch. Thought cruisers like the four blades... I have 23 lab miages laying around..shame they wouldn't work. Yes. Feel like I need more bow lift..bravo 1 prop did well on my Sdi...just never heard of appola props. I miss 68mph! But thoses days are over.

What's the diameter? 16 is a very small pitch. You're positive there bravo1's?

Ya b1's diameter 14.3/4...

I thought that would have twin B2s but if you have B1s try picking BBlades brains with all your performance data. They might be able to dial you in a little better prop wise. 16 is very weird if you have 1.5s. Usually with twins you can spin a higher pitch.

I just acquired the same boat though with volvo's, I stumbled across a site that had those toggle switches, I need them as well. You can try partman.com as well. they may have them.

hhhhhhhe wants to go with rev 15's...strange. anyone run this boat anymore? trying to get a baseline. I have emailed forumlaforum three times, they never respond and I cant register...I.D.C.E...can you ask in there? I have searched too , no avail. much appreciated

Mine came stock with 3 blade 21 pitch Michigan wheel props that r for sale if u want to try them pm me if u do
Mike

thanks...i have a pair of 23p ss mirages i could test. but what was the wot when new for this boat, non mag 454's? what kinda numbers you getting with non ss?

Never tried them upgraded engines when I bought it these are stainless props

What ya upgrade to?

Sure, same screen name?

lyuba.vitelli at gmail email response would be great. I'm also wondering what three blade pitch make the best set up...as well as upgrading to Bravo 3's. Even if anyone is running Revolutions 4. Thanks IDCE...mike im not happy with the 3200 cruise at 29 mph. just doesn't feel right. wot is 41 at 4500 w/ 16 pitch Apollo's.

seems to work now... thanks.
