Air actuated silent choice
 

I'm changing from electric to Pnuematic silent choice. Who makes the expolsion proof pumps (compressors). Frankly there does not look like much difference between the high dollar marine one and the cheap tire inflator that you can buy at Walmart.

Any input would be appreciated.

Thanks.

Dude what happened to the switchable muffflers?

Re: Air actuated silent choice
 

Why are you changing? I just removed my Merc silent choice because it was a PIA. My friend has Corsa with the electric selonoids and never a problem.

Caught me....Final prototypes are done and tested. Production on the way but need a compressor.

Re: Air actuated silent choice
 

The cheapy should work as far as the compressor itself, not accounting for the spark factor. Course could alway mount it elsewhere, but you will need to install a pressure relief valve, and a solenoid to vent the lines for switching.

Go to your local magazine rack & pick up a copy of "Truck'n" Magazine. All the truck/car suspensions with air bag systems use a full aray of different size compressors. The biggest name in air pumps is "Aim Industries" for air suspensions. They are by far the cheapest source. They are the same pumps used on Merc Silent Choice, Corsa, etc... Hope this helps. Ed

Usually they get switched FROM the air to the Corsa-style electric.
Good luck on the prototype.

Re: Air actuated silent choice
 

Had electric on my donzi as well, never a problem.

Re: Air actuated silent choice
 

look at the ones from viar, have had trouble with the ones from aim on truck apps. Parker also makes a compressor as well.

Re: Air actuated silent choice
 

Who make the electric style ones? Where did you get them?

Thanks.

BTW, Here they are after one season....a little dirty but they cleaned right up.

Re: Air actuated silent choice
 

Im ditching my air activated Merc silent choice this year too (twin set up)........Ive probably spent more time effing with that system than evrything else combined.....works one weekend then not the next :mad: ........I do work with pneumatics at work and theres one thing you can always bank on........LEAKS!!!!!........in industry its kind of ok.......in a boat..........NOT OK!!!!!!!............"hey doug, your boat is really quiet"....."yeah I know......never mind" :rolleyes: .......doug

Re: Air actuated silent choice
 

Mine were Corsa and the complete kit was about a grand for one motor, comlplete with wiring harness. got them online but I cant remeber the name of the place. Do a google search on them and it should come up.

Re: Air actuated silent choice
 

I have a complete deluxe pnumatic kit from CMI that I never used. I adapted my Corsa solinoids to work with the CMI diverters. It includes the pump relief valve and wiring harness I think. Think I paid around $400 for the kit but I will let it go for less. Ill have to dig for it so let me know if you want it.

Re: Air actuated silent choice
 

Thanks guys. By what you said I'd be interested in the solenoid style. Anyone know what type and make they are?

Re: Air actuated silent choice
 

Corsa. They have been called "Captain's Call" and "Quik-Quiet". I see them on boats I survey all the time. Seem to be the best set-up without the Silent Choice problems.

Re: Air actuated silent choice
 

Corsa makes the system I have. Its been bullet proof. I was so glad to get away from the air system with all the leaks.

Here's a couple of pics of the Corsa solinoids on the brackets I made to adapt them to work with the CMI system.

Nice job, RJ.

Re: Air actuated silent choice
 

RJ...lookin good

Re: Air actuated silent choice
 

Boom?

Re: Air actuated silent choice
 

I did say expolion proof :D

Re: Air actuated silent choice
 

I have one! let me know if you need it for testing....

Re: Air actuated silent choice
 

i don know me and a frend have 96 fountains that are air,no problems. never,,

Re: Air actuated silent choice
 

you know Ive often wondered if my biggest problems are'nt with those pnumatic cylinders themselves but the price merc wants for them Im not going to bother on what amounts to an experiment- Im just going to electric and finally be done with it

Re: Air actuated silent choice
 

Had the Merc air on my last boat w/o any problem. Have the electric Corsa on my current one, nonproblem with it either, but it operates so much faster, and with less parts.
As far as the explosion factor using a cheapy air pump, who says you gotta mount it in the engine compartment? The plastic tubing is like $.05 a foot. Mount it elswhere. :rolleyes:

I Had Gaffrigs On My 33 Daytona And Had No Problems, They Would Bleed Off A Little Some Time But Were Very Reliable.

I believe it's Thomas industries.
The compressor is the same as used on Air Shocks in cars and trucks.
We parted out a custom made 1983 760 Volvo limosine about 10 years ago that happened to have a similar compressor, just bigger.
I am looking for some parts to rebuild some of the units. In the past I have taken mine apart and trimmed the flap down a little so it doesn't dig in to the pipe, at least in the same spot !
I guess I will have to take some apart to figure out bearing and seal dimensions and or numbers.
I believe the housings were cast by Wilcox Crittenden and were anodized.
My friend has been cleaning me out of parts. His get stuck and he hit's actuator arm with a hammer and sometimes breaks them. (2 motors 4 problems !) I would like to not have to weld or fabricate if I could just buy the small parts.
I'm going to rebuild 4 of my diverters for him over the winter to replace his. And then rebuild his.
