The
Powerplant
The VX™110 Sport is powered by a newly designed
Yamaha MR-1™ four-stroke engine. This is a compact,
ultra-lightweight, 110 horsepower, four-cylinder, 1052cc,
DOHC, 20-valve, liquid-cooled engine for class-leading
performance.
* Electronic Fuel Injection (EFI):
Delivers a smooth, high power output with low fuel consumption
and low exhaust emissions.
* Specially Designed, One-piece Cylinder
and Crankcase Assembly: Provides tremendous engine rigidity
that's lighter and stiffer than two-piece designs.
* Slant Detection Switch: Electronic
switch stops engine and oil pumps immediately if watercraft
becomes overturned, protecting motor from water ingestion.
* Dry Sump Lubrication: Uses two
engine oil pumps to deliver lubricated oil to each moving
part with water-jacketed sump and oil backflow protection.
* Yamaha Engine Management System
(Y.E.M.S.): An integrated, computerized management system
that controls and adjusts such functions as ignition
timing, fuel injection mapping, engine diagnostics and
OTS. The OTS function of Y.E.M.S. activates when the
operator releases the throttle lever and attempts to
steer the watercraft. This assists the operator in turning
while the watercraft is decelerating.
* Corrosion Protection System: Sacrificial
zinc anodes protect the engine from harmful galvanic
corrosion. Stainless steel fasteners (nuts, bolts, hardware)
provide a long service life.
* Electronically Controlled, Variable
Ignition Timing: For exact ignition advance control
at all throttle positions and RPMs.
The Jet Pump Propulsion System
* The VX pump design is one of the
most efficient pump configurations ever, increasing
stream velocity and thrust while decreasing cavitation
and prop spin.
* Stainless Steel Impeller Housing
Liner: For high durability, the liner maintains accurate
clearance tolerances between the impeller and the housing.
* High Flow Intake Duct and Grate:
The dynamic shape of these items directs water flow
into the pump for better thrust, performance and hook
up.
* Cooling Water Intake Filter: Filters
out harmful debris that could cause blockage of important
cooling water passages.
* Pumps are Manufactured with YDC30:
A combination of zinc and copper alloys, developed by
Yamaha marine engineers, that offers excellent corrosion
protection.
The Lightweight, High Strength Hull and Deck
The VX hull is designed to be light and strong.
* Progressive, V-Hull with Integrated
Bow Spray Guard: Provides excellent maneuverability,
handling and comfort.
* Performance Sponson Design: Provides
added straight-line comfort and an improved two and
three-up riding experience.
Additional
Features:
* Multi-function Electronic Information Center: Provides
the operator a quick read on speed, RPM, fuel level,
low fuel warning, low oil pressure warning, overheat
warning, hour meter, check engine light with self diagnostic
function.
* 19 Gallons of Total Storage: Includes
a large bow storage locker and glovebox.
* Comfortable One-piece Seat: Ergonomically-designed
and contoured for added support. The extra-long seat
is easily removed for quick access to the engine compartment.
* Extra Large Boarding Platform:
Provides a stable platform for re-boarding.
* Finger Throttle Lever: Provides
added comfort while reducing hand fatigue.
* Yamaha's Trademarked Visibility
Spout®: A waterspout from the rear of the craft
that improves the watercraft’s conspicuity.
