droop vs straight snoot
« on: March 17, 2016, 10:42:10 AM »
another opinion thread. im sure you all are tired of them

My rogers i do not have a diverter, instead i have a full AT droop and a set of wedges.

I needed some gaskets and cant get out of work to go get them so i asked my GF if she would run to GS marine and get htem since Eddie marine was out of stock.

She went down there and i called Greg before hand making sure he had them. He asked that i have her bring the nozzle for the new o ring since there are quite a few of them. I said sure.

Since im at work i couldnt pull it apart for her so she had to take the nozzle/droop assembled down there.

He highly recommended changing from the droop to a HPH nozzle. Said my droop was like a shovel in the water.

Being i have a ride plate, i dont see that really being that true? But further me not having  a diverter i figure the droop really helps with lift?

What would/are the benefits of changing to a straight snoot like the HPH? Especially in my situation without a diverter? I really think it would hurt more than help. Maybe he was assuming i didnt have a ride plate?

He even sent her home with a flyer. Just trying to sell something? Or would i possibly really see a gain? The boat rides pretty damn nicely now.

Further, back when the boat was built in 2006 by GS marine, they had it setup with a full droop. I'd like to hear everyones opinion

9 times out of 10 the full droop will try to lift too much boat out of the water causing the porpoise of death. If you have the HP and the boat rides and works well now, I am of the "leave well enough alone" mantra.

That being said,  if Shoe recommends the HPH, let him back it up.  Tell him you'll try it,  but if you are unsatisfied, he takes it back with only a 10% restock charge.

I think what he is going to tell is,   you will need a Diverter once you put the HPH on and try to get you for another $600. This is my opinion only and based on facts whatsoever.

What Droop do you have?

Where does the bottom of the nozzle end up in relation to the keel line?

Where is your ride plate set up and what angle is the shoe to the keel?

GT

Thanks GT I tend to agree with you on most of the above. And figure the same with the HPH and needing a diverter later

As far as your questions,
What Droop do you have?

I have an AT Droop

Where does the bottom of the nozzle end up in relation to the keel line?

I've never measured it based off of the keel line, only the ride plate. It was about 1"-1.5" above the ride plate. Ill be putting it back together this weekend and can re-measure it

Where is your ride plate set up and what angle is the shoe to the keel?

Its a normal 1/4" plate, i believe 18" long i can re-measure. shoe, etc. I think its about 3.75* "up" from keel line. I dont have an angle finder to measure it, but it was at 4 degrees before the shim, i think its about a 1/8" shim.

I might grab an angle finder/reader so i can get accurate measurements

This might be a pretty stupid question, but im going to ask anyway....

Where do i measure?

Do i find the keel infront of the intake, 0 out my reader there then measure on the ride plate for example?

Also, on the ride plate, where do i measure? At the end of the plate where the cradle goes? The middle? the front?

Same question for the shoe?

Not really a stupid question.

For starters,  I like to use a strake for getting keel angle. It's the most idiot proof.

The shoe should be flat so check that in reference to the angle you get from the keel/strake. You can always level the boat trailer to achieve "0" degrees. The ride plate would be angled "up" from the keel,  so when you measure the plate, you may have to take an average,  meaning the plates are not always flat. From what I have seen over the years is anywhere from 2° up to about 4° up seems to be a great starting point. By starting out at an extreme, the changes are more prominent.

If you have to have the plate way up (say in excess of 5°) I would say the shoe should be back cut,  if nearly 0° works,  I would say the shoe should be flat or mostly  flat. (Also called straight cut).

Be sure to document your changes and small changes are best for the most part. You likely won't get it "right the first try".

While you're under there farting around,  check the hull bottom for a hook,  especially at the strakes.

Also, don't forget to take a gander at the loader and it's hardware.

Thanks GT

I've crawled underneath it and checked it for hook, i dont see a whole lot of it there. Not bad by anymeans

The loader hardware is brand new.

Ill try the measuring this weekend

Jmo, leave the droop and throw a dam diverter on the thing already. I promise it will help bud 👍🏻👍🏻👍🏻

The only gain I can see with the HPN combo is rasing the thrust line.

I wonder if the HPH would help the porpoise in my boat. Right around cruising speed it starts to bounce and that's with no trim. I feel like the droop gives mine way too much lift. I know all boats are different, but every other Bonneville Classic I've seen has a droop on it. One thing I noticed is when I had people in the bow (more weight) the porpoising wasn't nearly as bad.

Put some down wedge in it? You can pick up the plastic wedges pretty darn cheap... Still might be able to have the best of both worlds if you play with some different wedges...

He has a Diverter, having a hard time processing what lowering the X dimension would do.

Ultimately I think a shorter droop would help you here.

Classic symptom of too low of X dimension for your set up.  Where is your plate at?

Gonna throw this at you.

You need a later model Diverter. I am guaranteeing you 2-3mph and a better ride.

As an experiment,  throw a straight edge across the keel at the pump and tell me what you see.

One more thing, what the hell is with that steering tiller bolt spacer thingomobob?  Lose that spacer and replace the bolt with a shorter one. To get the cable to move at the tube, replace the rubber insert and loosen it up.
