iFJF 18-7750-1 Carburetor Rebuild Kit Replacement for Mercury Mariner Outboard Motor Replaces 1395-8236354（Pack of 3）

The pros:Gaskets, needle and hose clamps all seem to work well. Fit the carbs correctly without any issues.The cons:The hoses are not the right ID for a 40 hp 2 stroke (2004). Used the clamps and got nothing but leaks. FYI, the correct ID for that year and hp is 3/16. You can use the clamps with the kit though. Last issue with the hoses, there are two places where you need a rigid hose. So it won't kink and to keep it away from the throttle arm. The supplied hoses kink and will not allow you to keep it away from the moving parts.So, considering the cost per carb and the fact I didn't use a lot of the parts, this seems to be an over prices option. If you can find just the gaskets, the float needle and perhaps the float in a kit that's a better option.I didn't use the springs or the threaded needles. Just the gaskets and the float needle. My carbs were really pretty clean.

The kits worked fine for rebuilding the carbs on a 1991 merc 90hp but the inline filters included with the kit are trash. They include a filter with each kit so you end up with a couple extra since the engine only has one inline filter to supply all three carbs. First filter I used cracked right at the base of the outlet hose. After tuning in the driveway and running fine for one of two trips noticed raw fuel leaking from under the engine cowl and rough idle. Found the crack by trouble shooting and pumping the hose bulb which caused fuel spray to be apparent at the crack. No biggie right, I have two extra filters. Put one on and tested with no leaks. First trip out was same story with fuel leaking from cowling. This time the filter cracked at the inlet hose where it joins to the filter body. The plastic on these filters is way too thin to stand up to any vibration that would be typical for boats. I'm throwing the extra third filter in the trash and replacing with a factory replacement. Raw fuel leaking into an engine cowling or in the water is no Bueno!

This kit contains all nessasry part, but the Needle seats are to small and in my case would not deal off fuel flow as needed and caused major flooding of fuel into the engine...so I purchased new OEM carburetors for the outboard motor

Came with all of the parts I needed and extras for other models too.Each of the fuel filters (3) cost $12.00. This is a great price.

Fuel line that comes with is that of poor quality . The fuel filters I couldn't manage to put on without breaking the ends off .. yes all three broke.. and the needles make my seats leak. This was used on a 87 mercury 70 hp I returned them and bought mercury own parts

Excellent tools and they send me in a exact time

Kits themselves were quality and spot on . The included hoses and clamps were sub par .

These parts must be factory rejects because the manufacturer never finished machining them. There were missing parts that were part of the assembly that were never completed during assembly. Not a good replacement.
