Good question actually...we were specifying a new boat late last year and were faced with the Suzuki 90 and 100 as options for our 5.3m boat. There was an 'old' 90 at 1950cc, a 'new' 90 at 1500cc and a 100 at 1950cc.

In the end, the 'new' 90 won over the day...whilst 10hp less it was a newer design promising lower fuel consumption/lower emissions throughout the operating range and, importantly, 35kgs lighter. No contest for me

I understand!i have same doubt about new suzuki 90 or 100!only 10 hp difference but much lighter on the stern and new technology!can you tell me please what boat do you have and what is Your fuel consumption?

on suzuki website they say that displacement gives you more option when choosing the prop!they said: "no replacement for displacement"

We have a Ribcraft 5.3 running whatever prop it came in the box with.

Limited running so far, but on the first tank of fuel, measured brim full to brim full and using GPS data, we did 8.0mpg (29.4 litres/100km). Can't give you a litres/hr figure...haven't enough data as yet to be accurate and meaningful. Bear in mind this was low engine hours running...gentle warm up, some low speed (8mph) up and down an Estuary, couple of hours cruising at 3000-4000rpm (20-25mph), one short burst of full throttle (40mph+).

We're away in the boat all next week...I'll post updated fuel figures after then.

No replacement for displacement is true, in a sense, but all things are relative to technology. An American muscle car of the 1960's with a big 7 litre V8 can now be easily outperformed by some European family hatchbacks of 2 litres or less that use less fuel in the process

Yes,i agree!!new 90 and 100 hp have same gear ratio,2.59:1,and in specs they say that it means you can put larger prop for better acceleration and top speed!

IT would be very nice of You to give info on fuel consumption!but these data so far are preety good,somwhere around 0.6 l/nm!!Thank you very much...
