four-
strokes all weighing in at
156kg, my preference would
be sticking the maximum-
rated 90hp on the Signature
495F – extra power can
always come in handy. In
saying that, the 70hp is a
brilliant motor and would
push the 495F along with
no issues while saving abit of coin up front and on
economy along the way.
Swinging a 19in prop, the
16-valve DOHC big-bore
1.5L Suzuki DF90 provides
effortless holeshot, a quick
and responsive throttle
throughout the rev range,
and impressive economy on
the 495F. Key to its holeshot,
and seen throughout the
Suzuki range, is the use of a
high-ratio gearbox. At 2.59:1
the propshaft is reduced
to spin more than half asfast as engine revs. This
means it can run props with
around twice the surface
area, giving masses of grip
off the line and in turns.
Another impressive DF90
characteristic is just how
quiet it is – from idle through
to WOT on the 495F.
What puts the DF90 at the
top of its game? It features
an offset driveshaft that
helps evenly distribute
weight by reducing the size
of the outboard, as well asproviding an increase in
power, performance and
balance, all while minimising
vibration.
Suzuki’s Lean Burn
technology adds more,
significantly improving fuel
economy from low speeds
up into the cruising and high
ranges – claimed reductions
are up to 45 per cent,
especially at trolling speeds.
The self-tensioning timing
chain is a big bonus – no
timing belts built into service62 trade aboat.com.au
