If you have broken the Brass Jet on either your older 30 Jet (4 Cyl) or 40 HP Mercury Mariner carburetor, I believe that I have just what you are looking for.

 

Originally my upper jet broke (This auction is for the LOWER JET), and I could not locate an OEM replacement, so I found a way to have them made.

I just simply could NOT throw away the whole and good motor for such a 'simple' part...

Some have asked for the LOWER JET as well, and I've finally been able to have it made as well.

 

This original part is No Longer Available from the manufacturer, but I have a small number of them that are newly manufactured (by reverse engineering) locally, tested on an actual 40 HP Mercury Mariner Outboard Motor in the water, and it works just like the original.

 

The price for ONE STAINLESS STEEL LOWER JET FITTING is $80.

Note:  This does not include any other associated hardware or seals.

 

The 40 HP & 40HP '30 Jet' (4 Cyl) Mercury part # is: 1395-823622 (LOWER-WMA-9/10/13) - The threaded end is 5/16-24 NF.  The standard bore is .050".

The link below shows the parts break-down (item 11, listed as 'Jet Assembly'), to ensure you are getting the part you actually need.

 

Unfortunately, Mercury has updated their parts catalogwebsite, so I can no longer provide a direct link to the Mercury Mariner “30Jet” or Mariner “40” parts catalog.

Here is the home link, and the steps to click for you toverify your part number:

If ebay removes the link in this message as well, simply google "Mercury Marine Parts Catalog" and one of the first links should be the same parts catalog...

Shipping cost within continental U.S. only is $5 each for standard USPS, contact me if you prefer faster shipping options.

 

I will combine shipping if more than one jet is purchased at the same time.  Please send a message to verify you are buying multiple or both Jets when you purchase to ensure I do not ship one before you purchase the second or additional Jets.

 

International Shipping:

 

I use USPS Priority Mail International Flat Rate Box for international shipments.

Depending on the destination country, this choice usually comes with a delivery confirmation and is significantly less expensive than any UPS/FedEx option I have found.

I cannot be held responsible for USPS to International Postal Service delivery issues, or when delivery confirmation between the two services is not available.

Once shipment is confirmed delivered to receiving nation Customs Agency, all issues must be resolved by the buyer with the Customs/Postal Service of the destination nation.

 

This item is sold as-is, no warranty or guarantee.

 

If you are looking for the Upper Jet, part number 1395-823621, that is available in an auction here:

*****Custom Jets are also available!!!*****

 

In addition, I have had some custom high-altitude jets already made, with adjusted altitude bore diameters, per the manufacturer specifications.

If you are interested in a non-standard bore for altitude, here are the altitude specifications and Part Numbers from the manufacturer:

Standard Jet up to 2500’ Bore .050" Part No. - 1395-823622

2500’–5000’ -                 Bore .048" Part No. - 1395-823622--3

5000'–7500' -                  Bore .046" Part No. - 1395-823622--2

7500' & above -              Bore .044" Part No. - 1395-823622--1

 

If you want a High-Altitude jet, you may send me a message before buying, but you must also indicate in the 'message to seller' when buying your Jet with a non-standard altitude bore from the list above.

I try to ship as quickly as possible, so you must not delay notifying me you need a non-standard jet bore.

You need to inform me which altitude bore you desire when you purchase/contact me.

I will, upon receiving that request, substitute the requested non-standard bore you indicate for the standard bore at no additional charge.
