Outboard engines are FI???? Wow!! and how !

[Phil Lamovie]

Hi Ade etal,

Not only are the newer (larger) outboards injected but the two
systems in use are really very sophisticated compared to your
average passenger vehicle.

The "small" engine system is by Fichtel & Sachs (they also make
clutch components for Ferrari F1) this is used on engines up to
180 - 200 hp. The "big" engine system is by the Australian company
Sarich Technologies (famous for their 2 stroke air/fuel injection
car engines). 

The Sarich system has a special injector that injects both fuel 
and a proportion of the air in an effort to enable very complete
combustion.

The Clean Air Research Board is responsible for the Legislation
that forced the big 4 to go full on high tech.

If not for the sophisticated fuel/ignition systems the outcome
would have been 4 stroke outboards with c/v carbys.

This is still the most likely outcome for the smaller engines
(below 50 hp) as the power to weight is less of a concern
to fisherpeople than ski/race types. And the system cost is of more
concern to the manufacturers.

As far as sea water is concerned please see epoxy resin 
encapsulation as the perfect solution. "No sir we can't repair
the unit you will need to buy a new one."
