**NEW** Simon 3.0L part (Dry stacking)

[Simon]

This part dumps all the water from the poppet out of the cowl instead of going into the midsection. It is like dry stacking. It keeps all of the factory cooling. They are 195.00 + shipping . It comes with billet poppet spacer, hose, hose clamps, gaskets, bolts, diaphram, and a billet dump. 760-440-9334

I heard something about this, I also heard performance gains were impressive for the simplicity. Is this true? :eek:

[492slayer]

Hey Eric, Do I need one of these on the 335? By the way It's purring like a kitty on steriods!! Running great, hope your getting some of the Bass guys buying them. Mark

[Simon]

Of course you need one.Everyone needs one.

[03bignasty]

I think I need one also 492. I've got one of Eric's motor's. I love mine also.

[Simon]

03bignasty. I would like to see how much speed you get with this part. It is perfect for your motor. It would help Greg also.

[Massbasser]

Yes Dave (03bignasty) needs one, so I can see if I need one. :D

[Bluecat]

Are there any heat related problems? Water pumps or seals.

[Simon]

The water from the heads still dump in the midsection to cool the pump.

[MWILLIS]

What gains will you see with this modification and at what rpm level.

[time warp]

Will this help on a stock 300X??

[Skatin]

If I can get some clear weather I will test mine out. The quality is excellent with everything you need to install. Great product Eric.

[Simon]

here is one installed. the dump is on the skirt.

[CDave]

Of course you need one.Everyone needs one.

I don't have a boat right now, do I still need one?:confused: :p

[Skatin]

You should get one to put on your table. It is just a cool looking part. In other words yes you need one.. :D

[fastercat]

how much noise does it make how many DB with this before and after???????noise is a prob on my lakes:(

[Merc-Cruiser]

Can these be used on a 2.4/2.5? Thanks

[steve]

Like everything else they make, Simon Motorsports has offered another work of art. Way to go guys!

I finally went out yesterday and tested them. The only thing that I have missed about my old 260's was the sound. The 300's just don't have that screaming rubber band about to snap sound. Those days are gone. These motors sound awesome now. They are louder but I don't think you would have a problem at all. You wouldn't believe the amount of water that comes out of it...:eek: :eek:

[beer30]

What kind of performance gains did you see with this up-grade?????:) Chuck.

[Skatin]

Can't do any high speed runs yet. I'm still breakin everythin in. It must make more power and the sound difference is worth the money alone. Next time I go out I will take some video.

[Skatin]

Here is a vid. Sounds much better. More to come if I can get some weather without the winds..

[godspeed]

it wont let me open file

[stylishskier]

those sound pretty bad ass... I dont have much to compare them to though...

[fastercat]

i have a idea do you guys think you put a ball valve on it then you can have both???????skatin how hot do the midds get???be like silent choice??:D

[THE HOGG]

I DONT THINK SO. I HAVENT HELD ONE YET BUT IT LOOKS LIKE IT BLOCKS OFF THE ENTIRE DUMP HOLE TO THE MID.(THE BOTTOM WHERE THE WATER GOES WHEN THE STOCK ONE OPENS) SO IF YOU PUT A VALVE ON IT AND CLOSED IT ALL OF THE WATER WOULD HAVE TO GO THROUGH THE HEADS AND IT WOULD NOT WORK. I THINK.:D

[godspeed]

cant access the link can you switch it to something else :) im reallly interested in these for my 300 s

[Simon]

Try holding the control key down when you click on the link.

[beer30]

Skatin's engines sound great!!!!:cool: I hope he gets some #'s for us soon.:) I would like to use this on my 300X after I get it dailed in on the Quartershot.;) Chuck.

[godspeed]

finally got to see it , how does it sound as you are at idal in the water , does it still sound nice my boat sounds like i have fishing motors when im idaling around the hot spots of our coves , kinda sounds gay like that id like to add these just to sound mean

did you get the boat yet if so when are we going to drink a beer and christen it ??

[beer30]

:cool: Hopefully I will have it middle to the end of May. Can't wait to christen it too!!!;) Chuck.

They won't change idle much because your mid is full of water already.

[Skatin]

skatin how hot do the midds get???


Doesn't appear that heat is a problem at all. The water from the heads dump in the mid still to keep everthing cool. Notice on the video the amount of water coming out below the pee hole. It's a lot of water. I can't wait to make some speed runs.

[fishead1]

Can somebody tell me exactly what this part does and what dry stacking is.I am relatively new to outboards.I have a 30 shadow cat with 99 Promax 300's.

Yea, what fishead asked. None of the poppet water goes thru the strut anyway. What exactly are you drying out. Or is this for a motor that has no bucket?
Does the poppet still close at idle so the motor can warm up?

One other thing. What are you cooling the heads with. On a stock motor, the poppet dumps into two cavities on the side of the bucket. Those cavities are drained by 2 1/4" holes. The water that can't go out these holes is what backs up thru the heads. Any extra water you are dumping is not going thru the heads.

Whats your water pressure and head temps?

:) :confused:

[Simon]

They are for motors that have the can cut off or a different tuner installed.It diverts the water from the poppet valve that would normally go into the exhaust,out of the cowl. It is a little more than half of the water that is dumped in the midsection. It helps with acceleration and top speed. The poppet valve is still stock, so there is plenty of water pressure in the block. It runs the same temps and pressures as stock.
