Not from me. I would probably use about 60% of the fuel if I had a similarly powered 4 stroke or a DI 2 stroke.
I bought my 9 year old Yamaha 40 hp carb'd 2 stroke last summer for $1400 CAN (~ 700 pounds).
It is in perfect running condition and has seen nothing but fresh water for it's entire existence, so it's got alot of life still ahead of it.
If I were to have purchased a new Honda BF 40/50 or an ETEC 40/50/60/65, I would have had to spend an additional $7000 - $8000 to acquire one.
At today's gas prices here, that is about 6000 liters of fuel.
An average 2 day weekend fishing trip would involve a round trip of about 90 miles (some less and some alot more), which would consume about 60 liters of gas (about 1.5 miles/liter).
That means I can go on 100 weekend fishing trips funded completely by the money that I've saved by not buying the new highly efficient motor. Given that we have a 20 week boating season, that is 5 years worth of trips simply to cover the cost of a new engine and not even accounting for the additional
cost of fuelling a new 4 stroke or DI 2 stroke outboard.
I doubt that the ongoing maintenance costs of a 9 year old, bone simple, carb'd 2 stroke would run up any higher those of a new, but far more complex 4 stroke or DI 2 stroke.
Older carb'd 2 strokes are nowhere near as fuel efficient as the 4 & DI 2 strokes, but they can be much more economical
, especially for non-commercial applications.
