To Droop Or Not To Droop?

[GOT WATER ??]

I have a 73 Spectra20 w/a jc. If I am going to put a droop on it I know that I will have to get a jg or cut my jc.
I am going to to put a Place diverter on it first. Then we will see.
My real question is: Will I really gain that much with a droop?

I have a 21' Howard daycruiser, I put on Places new droop and saw an honest 2mph on GPS but I think handling suffered a little.
I did not have good luck with the bolt on ride plate no matter which way I adjusted it up or down my boat would porpoise wildly. http://www.goldenplasma.f2s.com/forum/smilies/tongue06.gif

The change in performance because of a droop depends on the hull some they help some they don't I belive the place diverter droop has 4 degres up in the design thats what causes the porpus I WOULD NOT INSTALL A DROOP UNLESS YOU HAVE A DIVERTER. You could install a wedge to see if that helped your porpus like a 2 degree down wedge.

[spectras only]

Got Water,forget about droop snoot.Keep your JC as it is,get a hydraulic operated placediverter ,it will give you the performance without the snoot.Put the trim buttons on the steering wheel for good positioning and quick feedback.All you need is to trim the hull out of the water for less vetted surface,and the placediverter will do it,to gain a little more speed.

can anyone tell me what to expect out of a place diverter as far as speed? I know it probably depends alot on the hull and pump (low pro 18' Tahiti with a JC). I've heard gains of 5mph and others say it's more like 2mph. While any gain would be good $600 for a 2mph gain is kinda pricey imo. I know I want a divereter at some point in time, but right now if all I'm gonna get is 2mph I'm thinking there are other mods I can make for the same or less money to gain the same or more.
Advice anyone?

I'm no jet expert, but you might want to consider holding the nozzle, and putting your thumb over the end. It works for my garden hose. http://www.goldenplasma.f2s.com/forum/smilies/happy15.gif
Then it would be called the "Bubbledeck Diverter". http://www.goldenplasma.f2s.com/forum/smilies/happy34.gif
Just trying to help. Let me know if I can be of further assistance.

Bubledeck, your gains should be 5 to 15mph. I`d say that diverters are gonna give you banmg for buck more than any other mod.

[Bubbledeck2]

HH actually there is something you can do to help. I want to try your theory, but after doing a dry run just now in the garage I find that I can't reach the wheel while holding my thumb over the nozzle .. so if we meet up in Havasu the 22nd, that will be YOU'RE job to thumb the nozzle :-)

[Bubbledeck2]

jroos that sounds impressive! I'd spend the dollars for that!

DONE. You don't have to ask me twice to go to Havasu. I better start thumb-wrestling to get in shape. Of course, I will probably get parched performing that job...I'd better hydrate myself, and carbo-load for the trip. http://www.goldenplasma.f2s.com/forum/smilies/happy33.gif
Any suggestions?

Love that diverter idea, that shit was funny, never knew that about you Hangtime. 6 months!
Back to the droop, this will help.

A diverter is not going to give you 5-15 mph increase in top speed. No way no how. Maybe 3-4 mph assuming your pump is set up negative to the keel. The best assets of the diverter are in my opinion: 1) Trimming capability for rough water/smooth water, 2) better holeshot (less bow lift), 3) better economy (setting it properly gives you better speed at a specific rpm), 4) better turning, 5) its more fun to drive the boat with one, and 6) throwing the occasional rooster!

I did not gain that much in top speed with my diverter, maybe 2-3 mph, but I love the gains in handling. Rough water is handled better, the boat comes unglued in glass, no more porpoising, on plane faster, plane at slower speeds (for small childrens' slower ski speeds, or wakeboard speeds), plus the fun to be had with rooster tails.

Hey jroos 5 to 15mph thats a big spread I dont think you would get 15 with out HP or a Hook removal (Please professionals only DR)HARHAR JMHO
Rob (thinking i want some of that 15mph stuff your smokin)

[old rigger]

rivercrazy,jetboatjake,caribbean19,
you guys are right.
They (place diverters) use to be advertised to only improve the verstility of the boat, if I remember right. Even in adds today they say 'improve top end performance', not speed. But small gains in mph are always a happy by-product! Can't think of a jet boat that couldn't use one.
Frank Place and his family are some of the nicest people on the planet too.
15mph for under a grand investment?
Sign me up.

Old Rigger. You da man. Your knowledge here is really appreciated.

[GOT WATER ??]

Hey guy's thanks for all the input. I and going to go with the Place Diverter.
Last night I bought a Garmin etrex gps. What a cool little unit.
I am going to run my boat with no changes to get a speed reading. Then after I install the Diverter I will post the difference.

[Bubbledeck2]

GOT WATER I was thinking of buying the same unit. You're talking about the yellow one for around $119?
As for the diverter HavasuHangin has just about pushed me over the edge to buy one. Something about him thumbing my nozzle just doesn't sound right.

[GOT WATER ??]

Bubbledeck, Yes it is the little yellow unit. I love mine it works great.
48.2 mph 2 people and about 40 gallons of gas.

[SPECTRABRENT]

Got WAter,
I have a Short droop on my Spectra and I picked up about 3 mph. I also have the place diverter.
I have about $3,000.00 in my pump with the ride plate.

Anyone interested in Buying one of Frank's Droops? I have one For Sale. See my thread 'For Sale: PDC Droop Snoot....'
Thx, HRr

[77Spectra]

I gained 5 mph with my 19.

[ChetCapoli]

I remember calling Place diverter and needed a diagram sent to me on how to hook up the trim gauge which i purchased used from someone. Should have told them i bought it new and maybe they would have sent it. http://free.***boat.net/ubb/frown.gif
So old rigger i have to disagree with ya on that one.

I phoned Tim Place to ask some information about why I had a splashing issue with the Daytona, and he spent half an hour with me diagnosing problems, offering information regarding how to set up a ride plate, and how to spend some time detailing the shoe on the intake. This, on a pump and diverter purchased more than likely in the early eighties.
More recently he has helped (as did Rick at CP) flush out a cavitation demon and top end loading issue.
Nothing but love for Tim and Frank. Keep in mind that Frank Place is the father of the rooster tail! That is truly what separates us from the primates, I mean props...

I was driving to a cool junkyard out in the middle of the desert in AZ. and I asked this old Gila Indian guy how much further it was, he said " Oh, yeah dat place is uh, bout two or twelve miles that way." It was 25. I think he went to the same school of estimation jroos did! I am still on the fence about droops. I have been told by equal amounts of people that they speed you up, and slow you down. Some saying it makes a difference if it is the "long" or "short" one. Either way I think you should take you 600 clams and buy a nitrous system, and have a professional install it for you. Nitrous rocks. If it installed properly is it very reliable and causes no harm to your engine. Stay mild, around 75-100 horse if you have a stock engine or go up to 150 if your have the bottom end. Get a diverter to. Actually get that first, the get the bottle. You will get an honest 400 rpm out of your engine, which is very noticeable.
