What is the smallest Fuel Injected outboard?

[Rabbit]

Hi there,
I am wondering with
Fuel injestion systems on modern outboards
Being so efficient, what is smallest and how efficient?

What does the pannel think?

kind regards,
Les.

fuel injection needs electricity, and small outboards are pull start and dont have a battery for electricity. For a while that meant carbs had to be used on small outboards. Recently, manufacturers have intorduced a system where the first pull of the starter rope charges up a small battery, which powers the EFI, then the second pull starts the engine. I think Merc/Yam are doing this, can't remeber, down to 10hp engines. Can check on their websites

If you're talking injected two-strokes I believe the smallest models at present are 40hp.

I wasn't talking 2 strokes, I wasn't specific as to 2 or 4 strokes. There are definitely EFI outboards below 40hp though.

Hi,
Thankyou for your thoughts.

Surely the company to produce a small injected unit would make a step change on the competitors.

I vision,
2, 4, and 6 hp light weight, quiet, fuel efficient and reliable units.

I feel it would be a win win.

Lots buy new,

Lots sell old,

All could afford to get out even if its only in the dinghy.

Only a small light, but better than no light.

But a 4hp 4 stroke sips fuel at about 1 to 1.5l per hour. Even a large increase in efficiency wouldnt make that much difference

JFM,
I didn't know that 4 stroke EFIs below 40hp were available. I am sure that there are no 2 strokes though as I would really like a 25hp EFI 2 stroke.

Evinrude have a new 25hp 2 stroke etec (EFI) for the 2009 model year. Available in US now, just about to become available in UK. May be at LIBS I'd guess?
