Depends. For displacement speeds (7-8 knots), that is a perfect engine. I believe that is a semi-displacement hull, so it is capable of speeds above displacement speeds. I'm guessing it was re-powered.

Could be a great engine for that boat if, like most people, you'd stay at or below 8kts. Another 110hp would probably get you to 10kts at 4x the fuel consumption - hard to see when that would ever be helpful.
Also, a single 110 is likely to make your life much much better when it comes to maintenance versus, say, twin Lehman 120's. We have a CHB41 with twin Lehamn 120's and I'd prefer a single, particularly if it had a bow thruster.
One thing someone is sure to point out: if you are going with a single, you'd better make 100% sure it's maintained and tip top condition.

We have a single 135. Maybe we use 1/2 of that HP to cruise at hull speed (Just under 7 knots). A single 110 is plenty for that boat. To get a 36 "over the hump" on to plane would take probably 4 times as much HP.....and fuel. If its a well maintained engine it should be a great fit. (Diesel I am assuming)

You'll maybe get 7 knots downhill, probably more like 6.5. Pretty old engine.
I have twin Cummins 210 turbos in mine and cruise comfortably at 8.5 knots at 1600 revs.

Is it a 110 Lehman, same block as the 120?
Anyway, ask the seller at what rpm they run the boat and what speed it runs. This info will tell us much more. I had twin 120 in a GB36, it did 12
5 at wot.
Don't expect more than 7 for cruise, maybe 9 at wot.
