I have a 120 hp Mercury Force, it is very cold natured and is hard to start I have NGK plugs in it. Is there anything that can be done to make it easier to start.
Note: the plugs look different than any plug I have ever seen, it dosen;t have the little melt hook that comes off the plug. It just have like the flat piece that is on plugs and is in a pit or something. Sorry the description isn;t that good.
Try the mechanics corner, boats, motors and trailers. I bet scrapper could tell ya something, he helped me out with my outboard and my dads outboard. He is pretty sharp, hope that might help alittle.
Bring a can of starting fluid. I have a 115 and is cold natured. This helps me when it won't hardly start.

Those plugs are normal in force motors I have a 90 force and it is cold starting to, Allways pump the fuel bulb till it is hard helps, those plugs are esey to foul and hard to clean.
Rowdy is right on with the bulb advice. Also are your sure the choke is working properly. Do you have a manual and/or remote choke.
I don't know anything about a Force, but my Yammy won't hardly start if the choke is not completely engaged.
Does it start well each time after the intial warm up ?
I had a 50HP Force a couple of years ago that had the same type of plug and it was a little cold natured also. To get it running when cold I had to choke it to get it started and once started I had to keep hitting the choke every few seconds until it warmed up a little after that it was OK. MY choke was one that's on the key and you just pushed it in.
Thanks for all the information
My choke is built in the starter. How do you check the choke in those situations.\
You should be able to depress the key while in start position, at least my Yammy and Evinrude both worked that way.
You should hear a click as the butter fly plate close on the carb air opening.
Take the silencer (breather) off the carbs and activate the choke, you should see the choke plates (or plate) close across the opening.
Good luck
should be able to turn the key on and push in to activate the choke with hood off the motor and air cleaner removed, mine didn't have an air cleaner, you should be able to see the choke flap open and close. If it doesn't check to see if current is getting to the solenoid, if it is and it doesn.t move then most likely the solenoid is bad. if it works then check linkage to choke if that's not it then I'm lost from there.
I forgot to say mine has always been hard to start but after running for a while starts on the first bump, I use the cold start or fast idle while the truck is being parked then its good for the rest of the day
How old is the motor?
You may have a weak fuel pump.
