any advantage in going with a 2 shorty or disadvantage

I have been wondering about the samething

Frank has answers

well tell frank we are looking for answers

U gain speed ,,but since they are hard to get on plane,,its going to be even harder,,,not worth it in my book.
U gain maybe 3-4 MPH top end but thats it.

Hard to get on plane ? If put my tabs down drives in my boat planes quick and on the top end tabs up I have to keep my drives up or it feels like my boat is going to nose dive

Mine was a 1990/91 ,,so maybe there is a diffrents in the X-dim. ?????

So just ,,never mind.

If thats the case on yours,,then it would probl. work !

Sorry

Yours was most probably 17 1/4". On the 1997 models the X was raised to 18 1/2".

JROMY on this board had the last PP ever built. It utilized the Merc ITS system, Bravo XRs with the Sportmaster Shorties. He had the anti-cav plates on his drives which made getting on plane fine. He broke one once and found it next to impossible to get on plane. However, with twin 525s, stock Bravo 32s, and his shorties he could get 87 out of it.

I am still on the fence with this one.

I just my have to be the lab rat and try extension boxes and shorties. The motors should be complete next week. We changed up on the heads and cam again looking for more power.

Never satisfied!!

Well,,,i had extension boxes on mine with standard length IMCO's and went to the bottom hole of the stellings ( -2 )

And i think i could went more?? But it defenetley was a better ride then before .
Twin 650-700 and ran 108 MPH ,GPS @ 6500 + RPM with 1:36 gear and 28 pitch bravo 1's !!

My four blade 32 Bravos had no trouble getting on plane, but like Indy said, I lost a cavitation plate once and that made a huge difference. The prop would always blow out.

During low tide, I also ended up running aground at the launch ramp (brilliant move), which very slightly burred up the ends of the props. After having them repaired, the boat was never the same and almost always blew out while getting on plane. You had to feather the heck out of the throttles. Another strange thing was that if you dropped the tabs, it had the opposite effect of what you'd expect - this would apparently cause more turbulence in the water and would make the props blow out much sooner.

That being said, just before the boat got stolen, I was planning on changing to 5 blades which are really the right setup with the shorties. I would not at all hesitate again to use them (the shorties).
