    Default Droop on a 21' Open Bow

    Anyone running a droop on a 21' open bow? I know they are not performance boats by any means, but just woundering if the droop would help it out of the hole alittle better.

    I doubt he has any in stock, but it only takes a couple days to get them

    The speedo read 52mph with 6 people in it, but the speedo's on boats are hardly accurate. I would say the speed was probably closer in the 40-45mph range.

    b-w, i'll call him up tomorrow, thanks.

    i have a droop on my 21 shockwave it is running a 502 with inducer and ride plate and an A impeller bought it that way seems to come right on plane but i think it causes the bucket to drag in the water and makes it a very stiff steering wheel that only frees up above 40 MPH if you put one on let me know if it affects your steering boat rides well starts to bounce if diverter is up to high i think it rides dry at speed this pic it's running over 50http://www.performanceboats.com/images/attach/jpg.gif boat tops out at 62 on GPS

    It does run dry in the pic you posted. All the jets that I had, they would ALL have stiffer steering when the diverter was up. This boat doesn't have a droop and its alittle stuff when the diverter is up, even with a steering extension. Thats just a nature of the beast though. I once had a little 18' SW with a droop and diverter without a steering extension, NEVER again..lol

    With these heavy boats, they will definately purpoise at higher speeds with the diverter up. Im sure it has to do with the uneven balance. 62mph is a good number. I'll be happy with 70, once I build the right motor one day. Nice boat by the way!

    Yes it is his old boat i lost some MPH when i put baffles in the exhaust that knocked it down a bit and he did say he had it up to 68 MPH with just him in the boat and i clock it with my Garmin out of my truck and i had my wife, ezup ,chairs, cooler and some other required river gear the only other changes i have made to the boat are chrome,powder coat and some stainless steel to replace the aluminum diamond plate and polished aluminum

    Nice to see the Shockwave 21's out there! I am hoping to see over the 70 mark with my new motor. Taking it to Shockwave for new interior on Saturday.

    02 Cobra 21' open bow, probably heavier then most, after 2 years of owning it I put a droop snoot on it and it made a world of differance, not only did I gain (i say ) 5mph just the handleing of the boat and the ride was so much better, I would recommend everybody with a 21' put a droop on with a hydralic place diverter...As to your question of helping it get out of the hole, probably not..just my $0.02 thou..
