If the Mercury Model 110 (9.8 hp) outboard you’re referring to has a blue band around the cowl, it most likely dates from approximately 1973 to 1977. Boating Forum – iboats Boating Forums+1

Here’s a summary of the evidence:

• One forum post states: “~1969 to ~1972 Red band … ~1973 to ~1977 Blue band” for Mercury cowling colours. Boating Forum – iboats Boating Forums

• Another thread on decal styles: for years ’72-’76 the classic tilted-letter logo had “blue and chrome”. screamandfly.com

• A comment from one user: “blue is 72 and up area” when discussing a Mercury 110 with a blue band. aomci.org

Caveats

• These colour-band indications are approximate; Mercury used serial numbers for exact production year modelling rather than relying solely on cowling colours. maxrules.com+1

• The blue band does not guarantee the exact year, so checking the serial number stamp on the engine block (usually between transfer port covers) is the best path for exact year identification. JustAnswer+1

If you like, I can check a serial-number chart for the Model 110 and narrow it down further for your exact engine—would you like me to dig that out?

Short answer: the mid-1970s (the blue-band 9.8/110 era) used the side-to-side manual tilt-lock lever, while later models (late-1970s → 1980s and onward) increasingly used the small up/down tab style on the clamp/swivel bracket.

Why: parts diagrams and old parts listings for the 7.5/9.8/110 family from the 1970s show the conventional sideways tilt-lever assembly; later service/parts chatter and replacement-part listings show the smaller up/down latch becoming common on newer clamp brackets. crowleymarine.com+1

If you want an exact confirmation for your engine (so you can match parts or restore it), give me the serial number from the engine block and I’ll look up the exact parts diagram and year for that serial range.

Good — since you don’t have the tag, the best practical way is to use serial-number ranges tied to the mid-1970s “blue-band” 9.8 / 110 family (the era that used the side-to-side manual tilt-lock lever).

Serial-number ranges that correspond to the blue-band / mid-1970s 110 / 9.8 era

• 1972 (approx.) — starting around 3,263,263 → 3,482,752 (1972 production). southcentraloutboards.com

• 1973 — roughly 3,482,753 → 3,795,657. southcentraloutboards.com

• 1974–1976 (mid-1970s) — roughly 3,795,658 → 4,691,221 (documents list the 110/11.0 series in this block for 1974–76). mibo.cc+1

How to use this

If the serial number on the swivel bracket (or cast into the housing) falls inside those ranges, it’s very likely to be a mid-1970s blue-band 110/9.8 and therefore fitted with the side-to-side tilt-lock lever. If it’s below ~3.26M you’re into earlier 1960s models; above ~4.7M you’re getting into the later 1970s/early-1980s changes when the small up/down latch becomes more common.
