This kit is about as close to a master kit as you will find. Lots of parts not usually found in today's kits. Mercarb marine carburetor rebuild kit. We offer 2 floats for this carburetor. The Nitrophyl float is like the original. Many prefer the brass which is also available.

Don't forget to change the float at rebuild time. These carburetors have nitrophyl floats and they absorb fuel over time. We now have brass floats available for these carburetors.

Carburetor Numbers:

Your carburetor may only have part of the carburetor stamped on the carburetor. I.E. 1389-9563A1 may be indicated as 9563



9562, 9563, 9564, 9670
Please match your carburetor number with the list provided. Using the application list above is no guarantee you will get the correct kit.

No return on opened kits.

There has been some confusion about how to measure the float level. The float used to have a small dimple on the tip of the float, which was used for the float level measurement. That dimple is generally missing. Simply use the tip of the toe as illustrated in the instruction sheet.

Cleaning - Soak all parts in a bucket of carburetor cleaner (any brand from parts store) for 24 hours, wash with hot water (remove all chemical). Blow out passages with compressed air. Run thin wire through all of the passage ways. Ethanol leaves residue in the passages that cleaners will not get out. Leave out any rubber part that isn't going to be replaced.

Great product and awesome support
I bought this rebuild kit for my 1998 Bayliner carb. The kit included everything I needed to do a professional rebuild on the carb. I went to a local marine store and asked for a rebuild kit prior to buying this. They told me that i would have to buy all of the parts separately for almost $250. I told them, I could get a rebuilt card for that price... Just crazy.. So I found this kit on Mike's carbs. I watched Mike's video on the rebuild and felt confident I could do this. It arrived very fast and I went to work on the rebuild. In the middle of the rebuild, I found that my carb did not have the ball and screen in the accelerator pump shaft and i had watched the wrong video. I called Mike's carbs and I was told there were several variations and that they would get back to me shortly. within 15 minutes Mike emailed me and cleared it all up. I finished the rebuild taking my time. It took about an hour but that included cleaning some of the old gasket off the carb. I took the boat out last weekend and adjusted the air fuel and idle. Worked great! I was having issues with the motor bogging at around 3k rpm and loss of power above. It's still bogging a little but I have full power over 3k. I am guessing that it needs adjusted again since this was the last piece of the fuel system that hadn't been rebuilt/replaced. i will be taking it out again this weekend and I think I need to give it a bit more fuel on the air/fuel mixture. All in all, a great product and amazing service. I highly recommend that you try to rebuild your carb yourself if you are even somewhat mechanically inclined. It will save you a lot of money and Mike's carbs can help if you get stuck. Thanks Mike!

MERCARB 2 BARREL
I bought this kit for my 1988 Bayliner 2 Barrel Mercarb. The kit arrived fast and included everything needed for the rebuild. Saved over $100 compared to local marine parts outlet. Mike's video on the rebuild was very helpful,. I used it during the rebuild process, pausing and rewinding as necessary. Great product and excellent quality of gaskets and parts.

Mr.
Kit fit but the internal gasket was different and I cut to match what was in my carb. My carb used the gasket with the square section seen in top row first gasket, however it was open above float like the next gasket seen. I removed the extra material to fit the same. Great shipping to Canada. Great videos, thanks Mike.

Great Product; Excellent Price
I had my first bad encounter with that crappy government mandated Ethanol cleaning my fuel tank. Clogged everything up. Kit had all the parts I need for the MERCARB 2 Barrel (1990 5.0L Mercruiser)and the online videos are excellent.
