I cannot give you a definite yes, but I have to say that with all of the part that are in the kit, that it would. It I listed for that year mercury OB.

You can look up the kit by application if you have the model and serial number of your outboard. This kit did fit my 1992 150 XR6 motor.

I have a Yamaha engine but I have seen the same one on a Mercury optimax. Should be fine.

This kit fit my 5hp B&S; engine on my pressure washer. I couldn't say positive it will fit your engine. You should research your engine and carb online to be sure. This type carb is on many B&S; engines.

If it's the same chassis and configuration as the 2003 it should. There's enough pipe to make it work. Especially if you're skilled at all, tons of room to fit and adjust.

I am sure it will, but it will take some moding. I have a car 250 and had to make special tools to make it work.

Shouldn't have any problems, it is a universal fit. I put it on my 2003 Polaris Sportsman 700

This Oxygen Sensor is a universal part that may require minor modifications upon installation. This will fit to 2003 Ch

I don't know. I have 7520 hp it should work for mine but it was very poor quality

I Installed this item on my Pickup with no problems. This should work on your Mercury, but Installation may be more difficult since the wiring is not as accessible as it is on pickups.

I have 2003. It has two numbers for each top sensor. But the bottom two have same number. If you put the number in ebay.com it will tell you waht it fits.

Can't say, I bought it for a 1985 60hp. They are pretty interchangeable but that is a big year and size difference. Very handy. See if you can find one on eBay. You can always resell it if it doesn't work.

It should pretty universal for the 150cc. I fixed 2 for a guy and had to make some changes on 1 but it worked other fit perfect.

It fists my year 2000 Mercury 150 hp motor. It is much better for your transom than those supports that mate with the trailer. I highly recommend this item.

I am not sure, I bought it for a 2003 ram 1500 pickup, I returned it because it was pretty complicated to install.

I'm pretty sure it will. I took one off a Merc outdrive and installed it on a 70 Hp Evinrude outboard. It's a pretty universal fit, like the Dolfins. Get the one with hinged plate, it costs a few bucks more but if you forget it one time or it self deploys in rough weather you will trash it when you take off. Experience speaking here, I have them on two boats now, a 21' aluminum and a 27' Cabin Cruiser. It will pull both down to .5 mph or less into the wind. I troll Lake Erie and they work great. Buy it from amazon, any problems and they fix it. Ray

Absolutely it will fit. That Mecury engine isn't made by Mecury. It is made by Tohatsu, which makes small outboards for itself (obviously) Mercury and Nissan. The only differerence is the paint job and the decals. I have a 2008 Tohatsu 3.5 hp and it fits great. The part that slips over the engine's tiller is also adjustable. You will have no problems at all.

Not sure. My application is a 1967 Mercury Monterey 390ci. And it works well. I believe it is more how the distributer is setup than the engine type. When I went to get mine I looked at the applications charts very carefully and it was listed for the 390. Good Luck! - John
