I’ve always viewed
fuel additives for boats – other than those offered by the outboard
companies – with a jaundiced eye. Some are definitely not good for
outboards. But for the last year now, I’ve been using an additive called
PRI-G (it’s new for recreational boats but has been used
commercially for many years). PRI-G has many benefits for marine
gasoline engines.
Most important, it stabilizes fuel for at least two years – even in the
carburetor, which makes it unnecessary to run the carb dry if the engine
won’t be used for up to a year. It also reduces cylinder head combustion
temperatures as well as inhibits both carbon buildup and corrosion. And it
helps keep the fuel system clean, while reducing harmful emissions. It has
even been successfully used to restore gasoline that is several years old.

Bob
White’s 38-foot Bertram, Island Time, had a smoking problem. It
generated an incredible amount of black smoke at startup, during
acceleration from idle and while coming up on plane after trolling. This
smoke left a thick film on Island Time’s transom that could only be
removed with Soft Scrub cleanser.
I’ll admit that two-stroke, 6-71 Detroit Diesels aren’t known for being
smoke-free, but White had done everything he could to keep the smoke under
control. He installed AirSep air-filtration systems to clean up intake
air. He dismantled and cleaned his turbochargers, and he inspected his
fuel injectors, which didn’t appear to be fouled. Clearly, it was time to
do something about the fuel.
There are many off-the-shelf products available to treat diesel fuel
ills of every kind. I wanted to try a new one. A call to Ralph Lewis at
Power Research produced a gallon of PRI-D "thermal stability"
additive. Designed to help reduce excessive smoke.
After mixing PRI-D with a tank full of diesel, White and I ran
the boat and found that, though not scientifically measured for opacity
and volume, the smoke plume was about half the size it had been under the
same operating conditions. The real surprise came after we got back from
our fishing trip. The transom was clean! - Jim Daly |
"This (PRI)
product that prevents fuel rot is literally an industrial strength
solution, with nearly the same formula used in ocean going vessels that
burn heavy fuel oil. Another benefit of PRI is the way it
freshens old fuel that has gone bad years ago. The good news gets even
better. In addition to protecting fuel from the ravages of time,
PRI-G also minimizes carbon deposits in the combustion chamber.
While this is aimed at carbureted two-stroke outboard, the carbon-busting
feature is also valuable on injected outboard motors and four-stroke
outboards, inboards and stern drives." - Motor Boat & Sailing, June 1999 |
A
heavy fuel oil treatment manufactured by Power Research Inc. is
demonstrating a capability to reduce emissions, providing an effective
answer to compliance concerns of vessel operators
The numbers for PRI-R are buttressed by a wealth of
data. The result is a dramatic extension of spare parts service life. One
vessel fleet manager reports he has doubled exhaust valve service time
between overhauls on medium speed engines. Yet another reports the same
results on slow-speed diesels. Universally they all agree that turbo
blades remain deposit-free, and waste heat boilers are free of any soot
deposits.
The PRI chemistries for diesel and gasoline have been
highly touted by industry leaders for their capabilities in preventing
carbon deposits in regular usage while keeping fuel fresh in long-term
storage. -- July 17, 2000 issue |
Bill
Poole, Owner, says.."With PRI-D, the
engines are running much smoother. There has been a noticeable difference
in power output. Additionally, there has been a marked improvement in the
exhaust area. There is not nearly as much soot on the transom as there
used to be, and what little is there is amazingly easy to remove. It has
really helped in keeping the vessel clean. Overall, I'm very impressed
with your product. I highly recommend the use of PRI-D in
any motor vessel" -- Bill Poole,

At Sea-Tow®,
we suggest the use of PRI fuel treatment in each tank of
fuel. Why? A vast number of engine failures at sea are the direct result
of fuel quality problems. PRI Marine Fuel Treatments are
industrial-grade chemistries specifically formulated to address these
issues, whether it is stale, degraded fuel, excessive carbon in the
engine, excessive diesel smoke, or algae slime clogging diesel fuel
filters. |

"As a competitive and winning tournament
sport fishing team, we depend on fast starts, reliable service and
performance plus. At these tournaments, the boats are at idle a lot. Our
competitors look at us and wonder why our engine doesn't carbon up - while
their engines are being choked with carbon, slowing them down for frequent
engine cleaning.. PRI-G is our secret weapon.
It's a remarkable product. As a NASA specialist at Cape
Canaveral, I'm very picky about what I put in my fuel, and I have
researched this extensively. PRI-G incorporates the most
advanced fuel treatment technologies available. PRI
simply has no equal. That's why PRI is the choice of
everybody here at NASA who boats."

"...PRI-D
will reduce smoke opacity ..by an average of 31 percent, The product is
supported by research studies showing a virtual elimination of carbon
build-up even after 550,000 miles of transit bus service. In one real
world application... staff added PRI-G to a 15-year old
fuel taken from a junked automobile and brought it into acceptable use
specifications. Although these are extreme - yet verifiable - examples of
fuel problems, they do demonstrate that (PRI) will indeed
improve the quality of fuel, thereby preserving engine performance and
improving economy."

"One
of my PRI-D clients recently told me that when he
overhauled his Detroit Diesel 12V92, he was amazed that there was
absolutely no carbon on the pistons and valves. PRI fuel
treatments are simply the best products of their kind available to boaters
today! I use them myself!"

Research differs from the other additive companies in that its product,
PRI-R, is all inclusive. ..PRI-R has
been formulated to recognize the complex interactions between carbon,
vanadium, sulphur and sludge that occur during combustion. ..Its product
contains a proprietary thermal stability chemistry that overcomes ignition
delay problems in marine diesel engines. One of the findings shows how
savings can be made on the replacement of exhaust valves. According to
these reports, exhaust valve re-conditioning and replacement wear
intervals were extended 70-80% between two vessels with PRI-R
treatment. - Bunker News Daily - 1998 |
"As a premier
sportfishing boat builder, service yard and Detroit Diesel dealer with a
strong national reputation, our primary objectives for products are high
quality and complete customer satisfaction. PRI-D meets
these high standards. Client feedback has been excellent, particularly in
the areas of smoke reduction, performance and slime elimination from
tanks." Chris Bellissimo, Marine

"We are one of the largest
marine retailers and wholesalers in South Florida, with a thriving local
business through our Miami-based retail outlet and through our export
business to the Caribbean and South and Central America.
PRI products move very well.
We've also had excellent support from Power Research. Our bottom-line is
that we want products that clients like and move in volume. We also expect
strong service from our vendors. This has certainly been the case with
Power Research and PRI fuel treatment products. I urge
any retailer of marine products to take on the PRI line."
Carlos Capote, Vice President, River

"As
a diesel fuel supplier and marketer of petroleum products to South Florida
recreational and commercial marine users, our objective is to offer the
very best products and services available. For this reason, we picked up
the PRI line two years ago.
We have not been disappointed. Although many
of my clients were using products we formerly carried - Valv-Tec and
Biobor® - they quickly discovered that PRI was superior
in all respects. Not only do we get strong repeat business, we get new
PRI clients everyday. I strongly urge any marine retail
marketer to make the switch to PRI."
David L. Sass, President, Anchor
Petroleum, Fort Lauderdale, FL |
"We
have four retail stores covering South Florida. People really like
PRI products and I can't keep them on the shelf. Today they are
far and above our leading selling brand for diesel and gasoline
treatments. I use PRI-G and find that it really does the
job. I especially like the fact that PRI has a strong
history in commercial maritime. I
urge retailers to carry PRI. You'll be doing your
customers a great service, and you'll also make excellent sales volume for
the fuel treatment category."
Dave Shields - Store Manager,
Hopkins-Carter, Fort Lauderdale, Florida |
"For several years we
experienced a very high rate of exhaust valve failures involving our
medium speed engines. This problem is directly attributed to the poor
quality, 180 cst fuel oil available in the operational areas of some of
our vessels. We have tried various fuel treaments with little or no
apparent success until PRI-R was introduced.
PRI-R Heavy Fuel Oil treatment has given us dramatic results -
and these problems are now a thing of the past. This is truly an
impressive product. We have also received excellent support from the Power
Research team, which relates to less down time and smooth sailing."

"Shortly after we started using your
PRI-D, smoke and transom residue was visibly reduced.
Before using PRI-D it was usually necessary to change
injectors about every 18 months. The boat is still running clean on
injectors that were installed more than 4 years ago. All I can say is YOU
HAVE A GREAT PRODUCT!"
Denny Falschlehner, Captain, Newport Beach,

Director, Western Outdoor News Fishing School
"I've tried many additives over the years,
but after running my boat (with a 200 hp Mercury) in La Paz with
PRI-G for gasoline, I couldn't believe the difference in the
performance of my outboard. This product is incredible!"

Captain Richard Ruffini, Bongos Sportfishing
With PRI-D, I've noticed a
great reduction in diesel smoke exhaust, especially at idle. My diesels
also run smoother and more effiicently."

I discovered PRI a few years back
and swear by it now. I have not tried or found ay other product even close
to it in what it does and it's performance. Family and friends who have
tried it also now swear by it and refuse not to use it or use anything
else in anything from expensive motorcycles to generators to chainsaws and
automobiles.
PRI is not expensive, really, really
works. No trips to the shop for lack of power problems, carb blockages, or
expensive carb re-building or injector cleaning. A few bucks per year
keeps you rolling and operating. All engines put out full and run super
smooth, just like new.
