Is this the old 90hp or the newer lighter one? In any case, you should see at least 5500 rpms.

I want that 740s!

It's the new lighter DF90A. I hit the limiter at 6300 rpm and 37.5 mph.
Yeah, the 740 is nice and coming down in price. It's way faster than even the 5200 series.
I was really bragging about the 6.9 mpg.

Good to see you Bit`s.

Light is good.

You guys suck with your MPG off idle.

Cheers,
GFS

So, does the Suzuki require a special kit to convert the NMEA from the motor to give you fuel burn? I believe that's what I read when looking around. I'm looking at getting a DF140 for my 20' soon. 6.9mpg is great!

Yeah, you do have to configure the output with a lowrance unit or the suzuki digital multi function tach (made by lowrance). Once that's done it'll run on the Garmin or any other nema network. It was a pain, but well worth it. The fuel burn is spot on and it also displays trim, water pressure, water temp, engine hours and rpm.
My Suzuki dealer let me borrow one of the units to get it configured.

What is the top speed with that setup?
