Mercury merc 110 9.8hp motor

[NastyNate32010]

How do I tell what year my motor is? Like I said it’s a Mercury merc 110 9.8hp. Serial number is gone. The is the motor cowl decal I have looked all over an cannot find it any thoughts?

Cowling graphics look mid-1970's. 1976-77 ish.

That’s what I thought from what I’ve seen. But every one I’ve seen with the 3 stripes they start thin an get wider on top have a blue top stripe.

Welcome to iboats

That Decal was used in 76 and 77. What's the Serial #?

 

[racerone]

Agreed----You can argue all day long.----But 76 and 77 were the only years for that style decal !

 

[NastyNate32010]

That’s the only one I could find with the decals that matched just had the wrong color. So thanks guys, I appreciate the help! All I can figure is the decal has faded over time.

One more question, the motor will fire up an as long as I give it gas immediately it will run a run GOOD as long as I’m giving it throttle. But as soon as I let off it will shut off. It absolutely will not idle. An ideas what that could be?

Gummed up carburetor or the idle screw at the top of the carb just above the air intake might need a tweak. (Assuming it is the Tillotson carb)

Mercury's serial number lookup web page is the ultimate authority.

Serial number has wore off

Nate said in the initial post that the S/N is gone. Maybe the motor has a dark past

When it was New, it looked like the one shown in Post #2

It should also be on an Aluminium Disk on the Block, that looks like a Core Plug

Yup, I frequently search CL and FB for those motors . . . Any original decals are all faded and look more silver than the original colors.

It is neat what Sunlight can do over a period of 45 yrs

Trouble shooting starts with a compression test.----Post your numbers.-----It will need a new impeller before your first fishing trip.
