Shallow Running With The Jet Set
By John Neporadny Jr.
 
While fishing tournaments on timber-laden Truman Lake, Richard
Bower just passes worried onlookers and runs through coves full
of trees.
“There are people waving their arms and trying to warn me about
stuff and here I am going 50 miles per hour over the top of it,”
said Bower. “I don’t have to waste my time idling out of a
2-mile long cove.”
When he prefished for a championship at Pittsburgh, Pa., Darin
Doll discovered the best fishing was in the Youghiogheny River,
a shallow river filled with gravel shoals. The York County Bass
Club member knew he wouldn’t be able to run up the river with
his 21-foot Nitro fiberglass boat, so he borrowed an aluminum
boat from a friend. The switch paid off as Doll won the
championship by running through the Youghiogheny’s shoals to
reach pools filled with smallmouth bass.
Borrowing an aluminum boat from a friend also helped Abe
Kalechman win a championship on the Connecticut River. The
Tobacco Valley Bass Anglers club member had no problem running
in shallows where no conventional bass boat could run to reach
unpressured fish.
These three anglers could run through standing timber or over
shoals without worrying about tearing up their boats because
they all were running jet-driven outboard motors. Commonly
called “jet boats”, these shallow-running boats are powered by
an outboard or inboard motor equipped with a pump and nozzle
assembly rather than a traditional propeller. “On an outboard, a
jet is a turbine system,” says Jeff McMillen of Troutt & Sons, a
boat dealership in St. James, Mo. “It pulls in water from the
bottom through the intake and turns a turbine and when it
releases the water, it propels the boat.”
Jet boats are ideal options for bass club anglers who do most of
their fishing on rivers or shallow stump-filled impoundments.
Bower used to fish Red Man tournaments out of his fiberglass
boat on the big lakes, but switched to a jet boat for river
fishing about 12 years ago. “I got to the point where I couldn’t
run with the big guys anymore so I decided to stick around the
home waters and fish the Gasconade and Osage rivers,” recalls
Bower.
“The jet boats are the only way to fish those rivers, especially
when they are low.”
The Linn, Mo., angler runs the rivers with a 21-foot Weldcraft
aluminum boat powered by a 300-hp Yamaha outboard that allows
him to run in about 1 inch of water at full speed. With the jet
drive, he never has to worry about tearing up a lower unit while
running through thin water or timber. “They are almost
indestructible,” suggests Bower.

“You can get a stick hung up in them and all you have to do is
pry the stick out and you are back going again. If you wedge a
stick in a prop you are going to bust an ear off.”
During his championship run on the Youghiogheny, Doll skimmed
over shoals about 2 inches deep with an Xpress 1756 VJ model.
The lightweight aluminum boat also allowed him to drift fish in
extremely shallow water. “A lot of boats are heavy and they will
sink down 4 to 6 inches when you stop, but that Xpress stayed
only about 1 inch under the water.” The Xpress boat also had a
center console so Doll could stand up to get a better view for
shooting through rapids.

Low maintenance is another advantage of running a jet boat. “All
you have to do is grease the pump bearing (attached to the
crankshaft) every other trip,” suggests McMillen. If the motor
sucks up some gravel, you might have to sharpen the stainless
steel impeller blade with a file, grinder or sander.
The cost of jet boats is also appealing to bass club anglers.
Bower suggests an aluminum bass boat with a jet drive outboard
can be purchased for one-third to one-half the price of a
conventional fiberglass rig.
Seven bass clubs in Bower’s part of the state hold tournaments
on the Gasconade, Osage and Meramec rivers where jet boats are a
must. Bower is a member of the Gasconade Bass Club, which holds
tournaments at various access areas on the three area rivers and
three events at the Lake of the Ozarks. During one club event at
the St. Thomas access on the Osage River, three club members
fished out of fiberglass boats, but the rest relied on jet
boats. “The jet boats were limited to a lock and dam that was 30
miles down river and Bagnell Dam (at Lake of the Ozarks) which
is 55 miles up river,” says Bower. “So we had a long way to go
whereas those other guys had only a few spots near the ramp to
fish.”
Centrally located in a river region, Troutt & Sons, Inc., sells
about 50 jet boats a year.
“We sell more jets than anything,” says McMillen, who estimates
the dealership sold about 20 jet boats to members from three
local bass clubs last year. The business also sold jet boats to
some Illinois anglers who fish stump-filled impoundments in
their home state. McMillan owns two jet boats and is a member of
the Meramec Bass Club, which schedules 10 tournaments a year on
the Meramec, Osage and Gasconade rivers along with Lake of the
Ozarks and Pomme de Terre Lake.
When competing in a club tournament at Lake of the Ozarks or
Truman Lake, Bower still uses his jet boat, which comes in handy
when he wants to run up shallow tributaries and feeder creeks.
However, his jet boat usually runs at a disadvantage on the
wide, open waters of an impoundment.
“Whenever you are in rough water and it catches air you are
pretty much sitting in the water dead,” he warns. The choppy
water prevents the propulsion system from working properly so
the boat loses power.

Jet boats can also be a disadvantage to club anglers if they
have to make a long run to reach their favorite spot.
“You might be able to go in shallower places but you are going
half the speed,” advises Bower.
Propulsion from propeller outboards is about 30 to 45 percent
higher than jets. Bower estimates his 300-hp jet runs at about
the same speed (51 mph on a GPS reading) as a 150 hp outboard
with a prop.
While venturing up the Connecticut River during his championship
victory, Kalechman could only run 30 miles per hour with his jet
rig of a Ranger Cherokee aluminum boat and 65 hp Mercury
outboard.
A lack of fuel efficiency is another drawback of a jet boat. On
the first competition day of the championship event at
Pittsburgh, Doll underestimated the fuel consumption for his
trip up the Youghiogheny and ran out of gas on the way back to
the weigh-in site. Rather than put a larger tank of gas in the
boat—and make the boat heavier—Doll decided to run the boat at
three-quarter throttle the next two days to save fuel. Although
it took him longer to reach his primary spot, Doll had enough
fuel each day to make it back to the ramp without incident.
Letting off the throttle helps Bower run at about 6 miles per
gallon. The Missouri angler estimates he gets about 4 miles per
gallon when running at full speed. On the 40-mile round trip
runs up the Connecticut River, Kalechman’s jet consumed about 12
gallons of gas each day.
Turns can be a problem for an inexperienced jet boat operator.
“There is no keel,” warns Kalechman. “It is a flat-bottom boat.
So if you are going as fast as it goes and you cut the wheel it
will just completely spin around.”
Slowing down will make the boat turn easier. “The steering is
fine whenever you are running straight,” says Bower, “but when
you want to turn, you always want to back off on the throttle in
the turn and then goose it a little bit.”
Although a jet boat can run at high speed in the shallows, it
has to shut down in deeper water. “Make sure you know exactly
where you are at when you are coming off plane to idle,” warns
Doll. “You have to be in a little deeper water to set it down
because if you don’t, you are going to bang up the boat.” The
jet also tends to suck up gravel into the intake if the boat
slows down in shallow water.
Aquatic vegetation can also be a nemesis to jet boats. “They are
very bad in weeds if you are idling, but if you are running you
will run right through them and blow them out because there is
so much pressure going through one of these things that it sends
the weeds right on through,” says Bower.
Despite these drawbacks, a jet boat is still the logical choice
for any bass club angler who wants to run shallower than any
conventional bass boat can run. Outboard jet engines range in
horsepower from 25 hp to 300 hp and are available in nearly all
lines of Yamaha, Mercury and Evinrude motors. Some of the
companies manufacturing aluminum jet boat rigs ranging from 17
to 21 feet long include AlWeld, Blazer, Xpress, Alumacraft and
Weldcraft.
McMillen lists 17- to 18-foot jet boats with 52- to 56-inch
bottoms as the most popular sellers at Troutt & Sons. The best
jet boats are constructed with either a true flat bottom or a
6-degree v-hull. McMillen recommends an 18- to 19-foot aluminum
boat with a semi-v hull and a 150 to 250 hp outboard for bass
club anglers looking for a jet boat that will allow them to run
long distances on rivers.
A trolling motor with plenty of thrust is also essential for a
jet boat used in river systems. Bower recommends equipping a jet
boat with a trolling motor that has a 24- or 36-volt system and
a minimum of 70 pounds of thrust. “You can’t stay out in the
current all the time though (with a 70-pound thrust motor), you
would have to get back behind eddies a lot,” advises Bower.
“Most river systems have anywhere from 7 to 12 miles per hour
flow and you really need a big trolling motor.” The Missouri
angler can stay out in the current longer since his boat is
equipped with a Minn Kota Maxxum featuring 101 pounds of thrust.
Any bass club anglers who prefer finding bass in skinny water
should consider a jet boat. It will take them to hot spots that
other tournament competitors are unable to reach.
Loaner planBorrowing a jet boat for a specific tournament is a viable
alternative for bass club anglers who already own fiberglass
bass boats.
Both Darin Doll and Abe Kalechman borrowed jet boats from
friends so they could run up the shallows of rivers to spots
that would have been unreachable with their fiberglass rigs.
Both club anglers arranged to have the boat owners’ insurance
policies cover them when they competed in their championships.
Doll paid $50 for one month on a rider policy which allowed him
to be covered by his friend’s insurance company when he
prefished and competed in his championship event.
“You have to be insured,” says Doll. “You have to make things
right.”
