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.

Rating 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.

Rating 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!

Rating Easier than anticipated
I've rebuilt carburetors before, and I have to say this was probably the easiest rebuild I've done. I followed the Mercruiser repair manual instructions, though it was straightforward enough that I probably didn't need them. My carb from early 1990s came apart easily, I soaked the body parts in cleaner, and all the new parts fit perfectly. I just installed the rebuilt carb on my Mercruiser engine, and it runs like new again. Not bad for an engine over 25 years old! My advice - Don't be afraid to do it yourself; it isn't that hard.

Rating Mercarb Carburetor Kit
I ordered this kit because my carb was leaking fuel and a steady drip could be seen when looking down the carburetor. This kit had all the parts necessary that needed to be replaced. The instructions were good and I had no issues besides temporarily misplacing my main jets, lol. The engine fired right up once I put it back onto the boat and ran great. I am very pleased with the quality of this kit and I will be puchasing another one to be ready for another rebuild in the future. Thanks!

This was my first carburetor rebuild. I bought the kit and suggested float. My repair manual and Mike's instructional videos enabled an easy DIY repair. Thanks.
