Better resale – again I am not positive about this either.
20-30% better fuel economy – DEFINITELY NOT! Take a 115hp
two-stroke direct injection on a boat and motor combination
with the same load and same speed as a four-stroke vs the two-
stroke direct injection the two-stroke direct injection will be the
same or more economical every time.
I will even go as far to say every brand of two-stroke direct
injection will be as good economically as their counterpart four-
stroke. The thing about the four-stroke is they are quieter and
have less vibration. The rest is up to the individual.
Another thing I do agree with; one day government legislation
will do away with two-stroke carbie engines to a degree but not
the eco-friendly two-stroke direct injection.
And, yes, I enjoy David Lockwood’s column about fishing.

[The two-stroke versus four-stroke outboard argument has
been going on for almost as long as I have been writing about
boats (first test appearing in print 31 years ago).
I have recently tested the latest four-stroke outboards with
Yamaha, talked with Honda, am flying to Milwaukee next month
to test new Evinrude technology. I currently own two two-strokes
and have owned four-strokes before. I had a long discussion
with Mercury about it all the other day, too. I drive boats will all
brands of new engines on them.
Unlike some in the industry, I ’m not pushing any one camp.
I am also conversant with the latest press and position
announcements released from the Outboard Engine Distributors
Association (two and four-stroke) and the Australian Marine
Engine Council (largely four-stroke). These come in the wake of
an announcement by Enviro Minister Hunt. It’s all very political.
Direct-injection two-stroke outboards have a long future.
Old two-stroke carbie engines don’t. Four-stroke outboards have
become more advanced, lighter, smarter, better performers. They
no longer lag behind two strokes on most every front.
Yep, I stick by my statement that “you’ll find a far more
agreeable form of pleasure boating with a four-stroke outboard
on the tail.” — David Lockwood.]
As a retired AMVER credited Met. Observer and Mate and
Master in the merchant navy for about 30 years, I have seen
countless sunrise and sunset Green Flashes when conditions
were suitable. Also I have twice seen the sunset Green Flash
Without complicating the explanation, the Green Flash is the
visible segment of the solar spectrum (rainbow colours) that we
see as the Sun’s upper limb passes your uninterrupted visual
horizon, at rising or setting.
It has nothing to do with one’s mind reversing a colour after
having watched it for some time, as Lance proffered.
Council opposes Soldiers Point
Marina development proposal
Port Stephens Council Senior Planner, Amy Garden, confirmed
on 7 May, that Council will not be supporting the Soldiers Point
Marina development proposal in its report to the Joint Regional
Planning Panel (JRPP) as no Species Impact Statement (SIS) has
been received from the applicant.
The JRPP consent hearing will be take place at Council
Chambers on 12 June. No matter what the JRPP decision is, the
proposal is likely to have to go to the Land and Environment
Court for final resolution.
This development proposal has been on the go since 2008.
During that time RMS has imposed a moratorium on all new or
replacement mooring applications in the vicinity of the marina
to the extent that some boat owners have been on the list for
six long years waiting and waiting until the Marina sorts out it
If the development is approved, 14 private and six commercial
moorings will be relocated from the sheltered waters adjacent to
Four-strokes versus two
I have been in the outboard industry for 45 years and don’t
see David Lockwood’s comments (Tech Talk, Afloat May ’14) tot ally
correct or give justice to all the outboards manufactured today,
especially two-stroke direct injection. I also sell a complete range
of four-stroke outboard motors.
“Four-strokes are making a charge to claim the top spot on Australian
boaters’ transoms,” he says.
A claim nobody can actually verify!
“Above 100hp it’s certainly night and day, with retailers finding the
old-generation basic two-stroke outboards lucky to account for ten per cent of
sales, the new direct-injection two-stroke outboards might rack up 15 per cent,
while four-stroke outboards enjoy 75 per cent of the larger outboard market.”
Where does he get these figures from?
We must remember only four of the seven major brands today
make two-strokes over 100hp, and the same for two-stroke direct
injection outboards. With one brand being different.
One thing I do agree with is that the old tech two-stroke carbie
gas gobblers are just about finished in the above 100hp market,
but not so for two-stroke direct injection. Also there are a lot of
older boats out there that a simple two-stroke will do whether
over 100hp or for the lower hp range. They just don’t get used
enough to warrant spending the extra dollars on a four-stroke.
Lockwood goes on with more rhetoric about four-strokes and
comparisons etc that are not quite true. He states the advantages
of four-strokes are No mixing of oil – on all two-strokes above 100hp
you mix the oil by just pouring it into the oil container. The down
side of a four-stroke is you have the oil changed every 50hrs and
filter at 100hrs and a mechanic charges you to do so.
Less smoke – well not so much on the two-stroke direct injection.
