Mercury 9.8 Reverse lock out?

[bunky]

I have a 70’s Mercury 9.8h.p outboard.    The reverse lock lever is busted, I have read where some guys say to leave it off.   I would like to fix it.  This motor has has the lever that goes side to side not up and down..

 

Do I leave it off or fix it ?

 

My problem with leaving it off is the motor locks down and I cannot lift it up when loading onto the trailer..

better fix it  ..if you hit something on the water severe damage will cost $$$

the  alternative is it disable the hooks   but the  leg will lift up is high  reverse

There are a lot of 9.8 and similar 7.5 HP motors around (at least in Minnesota where I live). If you need parts, look for a cheap “Parts motor” that has what you need. Other parts may come in handy later!

most of those  have a small flip up- down lever ?   pulling up a spring on the  lock hooks ..

I’m not sure on the year and serial number the tag on the clamp is missing..   the motor has a blue band on the cover and says 110.

Is there another location for the serial number?

My older 9.8 has the lever you press down to lift the motor.

 

This one goes sideways and I’m not sure I have all the pieces.

sorry all I find on 110 version is the regular small tab   lock release. wait for our Merc expert comments

I seem to remember that the 9.8 and 7.5 had a redesign some time in the late 1960s or 1970; and a lot of stuff changed, like I know the the carb was totally different, and ignition was improved. I never paid attention to the reverse lock to see if that changed, and my parts motor examples of each are too far buried in storage for winter for me to take a look to see if that mechanism changed also.

 Q: what year were Mercury 110 outboards with the blue band on the cowl made ?

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.
