I hope so. They have been getting there butts kicked with the other SV boat. The Fountains are old boats at this point but nothing has come close to challenge them IMO. I am looking forward to seeing what this new technology is capable of.

Whats up with that class? I thought it was a bigger spec motor like the Merc 850 package. Why would anyone run a 750 HP motor if the spec was much bigger HP? Confidence ? Orrrrr are they building bigger motors and calling them 750's so it looks good if they do good? Not trashing just asking what gives.

4.12.1 Materials - Crankshaft, connecting rods, pushrods and wrist pins must
be made of steel. Titanium or other materials are not allowed.
4.12.2 Single Plane Crankshafts - are not allowed. Crankshaft throws must be
timed in accordance with OEM specifications.
4.13 Heads:
4.13.1 Approved Cylinder Head - is the DART PRO I, CNC Ported
Aluminum Cylinder. Head Part #19574030. No other heads are
allowed. No modifications to the original head castings are allowed.
2016 Technical Rulebook Revised 9-15-16 Page 32 of 55
4.13.2 Spec Cylinder Head Serial Number - must remain on the head and may
not be defaced or altered.
4.14 Intake Manifold:
4.14.1 Carburetor Spacers - or adapters are allowed, maximum of 2.5"
between the bottom of the carburetor and the top of the manifold is
allowed.
4.14.2 Any stock cast intake manifold. The manifold may be port matched
up to 1½ inches to match cylinder heads no other modifications
allowed. No fabricated or tunnel ram type manifolds may be used.
4.15 Induction System:
4.15.1 Naturally Aspirated Engines Only - No forced induction engines are
allowed.
4.15.2 Approved Fuel - 91 - 93 Octane, no fuel additives or Oxygenated fuel
is allowed.
4.15.3 Number - Only one carburetor is allowed per engine.
4.15.4 Approval Carburetors - Any Holley Dominator style carburetor is
allowed.
4.15.5 Fuel Injection – is not allowed.
4.16 Exhaust System:
4.16.1 Any Exhaust System may be used with the following requirements:
The engine exhaust manifolds and pipes from engine outlet to point of
exit from hull or deck must be water-cooled by water jackets. The exit
from the hull or deck must be located in such a position whereby
exhaust fumes cannot affect the crew.
4.17 Transmissions:
4.17.1 General - All boats competing in the SUPERBOAT EXTREME
CLASS must have propulsion systems capable of turning the
2016 Technical Rulebook Revised 9-15-16 Page 33 of 55
propellers in either direction or maintaining a neutral (standstill) state
while the engine is running.
4.17.2 Single Speed - transmissions / crash boxes capable of forward, neutral
and reverse are allowed.
4.17.3Multi Speed – transmissions are not allowed.
4.18 Lubrication (Engine):
4.18.1 Wet Sump - and internal oil pumps are allowed.
4.18.2 Dry Sump - External oil pumps or dry sump systems are allowed,
however, a maximum of three scavenging pump sections allowed on
dry sump systems.
4.18.3 Intake Valley - must remain as cast with NO alterations to prevent oil
flow from the valley to the crankcase. No raised sections may be
attached or formed with any material around oil drain openings in the
intake valley. No “damming” or collecting of oil by any means is
allowed in the intake valley.
4.19 Ignition System:
4.19.1 Distributor - must remain in factory delivered location.
4.19.2 Electronic Ignitions - All Superboat Extreme Class Engines are
required to use the MSD Digital or Analog ignition system, limited to
6600 RPMS. A G2X Data Logger must be installed and maintained to
monitor the RPM Level during the race. The RPM level during the
entire race must be verifiable on the Data Logger by the SBIP
Inspector, upon completion of the Race, during the Post-Race
Inspection. The Ignitions with an internal dial up RPM Limiter will be
set and sealed by the SBIP Inspector. The wiring harness of the
system must be accessible and provide the ability for an SBIP
Inspector to examine it. No Dual Systems or Ignition Components are
allowed. Any boat competing in the Superboat Extreme Class that
exceeds the above listed MAXIMUM RPM LIMIT, as determined by
the SBIP Inspector will be awarded last place points and will not be
eligible for trophies, flags, or prize money.
2016 Technical Rulebook Revised 9-15-16 Page 34 of 55
4.19.3 Crank Trigger and Belt Driven Ignitions – are not allowed.
4.19.4 Coils - Ignition systems are limited to one (1) ignition coil. Individual
ignition coils per cylinder are not allowed.
4.19.5 Back Up Ignition Systems – are not allowed.
4.19.6 Spark - must be distributed via distributor rotor and cap.
4.20 Engine Supplier:
4.20.1 SBIP also will allow multiple engine builders to supply engines that
meet the SUPERBOAT EXTREME CLASS engine specification.
4.20.2 The Goals of Superboat Extreme Class - spec engine program are to:
4.20.2.1 Increase competitive balance throughout the fleet.
4.20.2.2 Develop an “8 race engine”.
4.20.2.3 Reduce the maintenance and operating costs for the majority
of the teams during an entire season.
4.20.2.4 Increase reliability and durability.
4.20.2.5 Increase performance and acceleration so the SUPERBOAT
EXTREME CLASS boats can negotiate the tighter multi-turn
SBIP courses more effectively.
4.20.2.6 Increase the number of teams that can afford to field
competitive SUPERBOAT EXTREME CLASS entries.
4.20.2.7 “Recession” proof its racing product by decreasing reliance
on outside third party suppliers for the propulsion systems
used in the race boats
