No, when running, it doesn't shift well when trying to get to and from reverse. Sometimes, it simply will not shift out of reverse. I have to stop the engine, rotate the prop shaft, shift into neutral, and then restart the engine.

Well, when running, I have had to rotate the prop in the water in order to get it out of reverse.

I have a 9.9 HP o/b mercury that I am having difficulty shifting. It is a tiller shift. Going forward from neutral and back to neutral - no problem. There are times it is very difficult to get into reverse, and once there, sometimes impossible to get back into neutral. Once this happens, the...

Well, took the pawl casing off and cleaned all the grease and gunk around the pawls and inside the pawl casing. One of the springs that holds the pawl in place may have come out, not sure. Cleaned them all up and reassembled - both pawls seem to be engaging on every pull, so everything seems...

Thanks. Well, there is certainly some grease on the pawls and inside the cavity where they sit. Should that grease be removed? Don't recall seeing any grease on the flywheel where the pawls engage. Doug

When I try to start my motor with the pull cable, occasionally it doesn't appear to catch the flywheel/crankshaft and i am "pulling air" (about 1 in every 3-4 pulls I will get no engagement). About 6-9 inches of cable comes out and then it catches. Was told it was probably the recoil spring...

Nope, just would like to know the size. Have taken the motor into a merc dealer to clean the carb and generally check out the engine. Lots of minor issues that I hope he can clear up, most of them associated with the carb. Pricing is weird though - spent $38 on a liter of gear oil for the...

The measurements I took of the old o-rings are correct. The problem is - the o-ring no longer looks like an o-ring. I assume over time it lost its elasticity and torus shape and became disc-shaped. The thickness of the disc actually equates to the distance between the bottom plate on the carb...

I heard back from Mercury - the part number for the carb I have appears to be 8M0176126, but I cannot find a schematic on their on-line parts catalog. They said the carb has been superceded several times over the years. Parts 44 and 29 you took from the schematics of the carbs from their...

Unfortunately, my o-rings now look like discs with a hole in the center. They have completely lost their circular cross section. For what is worth, disc diameter is 0.317" (7.98 mm), hole diameter is 0.141" (3.53 mm) and disc thickness is 0.053" (1.35 mm). I do not have the "as installed"...

Here are a couple of photos - I did hear back from Mercury -the part I am looking for is 898103224, which shows up on the diagrams you posted. However, I cannot find the configuration of my carb that has the priming bulb and hose configuration. Is there any way to find out the size of these...

My carb seems to have a different configuration from these parts diagrams. These diagrams I think show a later model of the carb that did not have a priming line and bulb hooked up to the carb.

The old o-rings were quite deformed like flattened donuts so any measurement of those would not give me the correct reading. My o-rings are likely metric. The chart you pointed me to are US sizes, simply converted to metric, so am not convinced the chart would work for me.

I have a Merc 9.9 o/b 4 stroke engine. The carb on this particular motor has a priming bulb and hose that attaches to the bottom of the carb. If you remove the cover where the hose attaches there are two small o-rings inside. Does anyone know the size or part number for these o-rings? They...

Ok, thanks. Will look it up.

What is the best lubricant/grease to put on the throttle cables and throttle cable assembly within the engine housing on a 9.9 HP mercury O/B motor for winter storage outside? I am in Ottawa, Canada, so the winters can get pretty cold and damp. Thanks. Doug

On my 9.9 HP Mercury O/B motor, there is a port on the lower gear housing beside the gear oil vent port that I think says "WASH". What is this port for? Thanks, Doug

Thanks, not sure why you have to put it in gear though. Doesn't the water pump work whether or not the engine is in gear?

I intend to simply put a tire cover on my motor (9.9 HP f4 stroke and store it outside over the winter (Ottawa Canada). The motor will be mounted on an engine stand, so it will be standing upright. I will change the lower end oil and engine oil before storage, but am a bit uncertain about how...

Thanks, I will certainly do that. Are there any aftermarket sellers of these carb kits? I checked with a local mercury dealer here (Ottawa canada), and they are looking at a $135.00 price tag for a carb kit, which is a bit on the expensive side.
