engineering a better performing engine
that weighs less and is more durable
than its competitors
was no small feat tehatsu uses
a single overhead can shaft instead of a dual
dual
overhead camshaft to reduce weight
without sacrificing
engine performance we have sought out
and adopted new materials to enhance the
durability tahatsu is known for
these new materials have also allowed us
to shed weight
to provide a lighter better product
our all new sheet molding compound is a complete
complete
integration of fiberglass and resin
processed through a heat press
this sheet molding compound is
introduced on the mfs 75 through 115
cali it's as durable as metal to resist
impact from debris and other hazards at
high speeds
but significantly lighter our team has performed
performed
extensive analysis to optimize each
relatively heavy component
our pistons connecting rods cylinder heads
heads
crankshaft and drive shaft housing have
all been designed to increase the durability
durability
aluminum components of the mfs 75
through 115
such as the cylinder head exhaust
manifold engine base
oil pan and lower unit are treated
through a special process to create a
better seal when anodized
in order to prolong engine life we went
to great lengths to develop this process
that allows for every part to be
corrosion resistant
here's an example of a non-anodized
surface versus our anodized surface
nearly 100 engines have been tested over
the course of more than
30 000 hours in more than 300 tests
multiple users tests have done in asia
the united states and in europe to
evaluate the durability through
endurance tests
to maximize durability our teams utilize 3d
3d
cad software to reverse engineer components
components
in order to optimize the shape of each part
part
one of the main tests that have been conducted
conducted
is the log strike test let's watch as we
evaluate the durability of the new
though this may feel extreme all tahatu
products are tested at this level before
they are released into the market
we are simply doing what we believe
should be the industry standard
when developing new products
let's go over a few more significant
technical enhancements
that will enable the new mfs 75 through 115
115
to last a lifetime we have added two
thrust washers on the crank case
to reinforce the durability and
longevity of the engine
we have also added a water pressure
relief valve that provides an easy way
to maintain the best performing
engine temperature just like the mfs-60
roller rocker arms and single overhead
camshaft have been
utilized to reduce friction and increase durability
durability
some manufacturers use dual overhead can
shafts yet the mfs-115 outperforms
and torque to displacement ratio our
team's exhaustive analysis has created opportunity
opportunity
for innovation in many ways for instance
we added a large capacity oil pump we
also applied a water-cooled rectifier
to reduce the size while increased
cooling performance
in addition to our innovative industry
first exhaust manifold
the exhaust ports for the cylinder head
are also uniquely designed
and angled to make it compact yet
durable there are two intake valves and
two exhaust valves
per cylinder which totals 16 valves
in order for us to design our
performance tuned exhaust
and minimize the weight increase at the
same time
we applied a single overhead cam shaft
we have gone
above and beyond to create an engine
built to last
for the purpose of increasing durability
and prevent corrosion
there are 16 sacrificial anodes
strategically placed throughout all
major components
in our next segment we will discuss the impressive
