Mid 90's 290 DA owners..? for you.

This is for single 7.4 Bravo 3 owners.

I need to know what ratio your drive is and what props you run?

I know it's 2.0 or 2.2....just not sure what came stock.

Thx

I had a 1992 290 DA and I don't believe the B3 was available then. You may want to call Sea Ray and talk to them.

94-97 290DA had the single 7.4 Bravo 3 as the standard set-up with the Bravo 3 as an option.The 4.3 twins were the other option with Alpha's and then a twin diesel option.

I'm just looking for what ratio the B3 is supposed to be.

From a Sea Ray Document I have for 1997 boats. You should have a 2.00:1 ratio with a 22 or 24 pitch set, depending on EFI/300hp or MPI/330hp. See below.

1997 290 DA IO 7.4LX EFI (300 hp) Bravo 3 2.00:1 22 pitch set 4600 WOT RPM

1997 290 DA IO 7.4LX MPI (330 hp) Bravo 3 2.00:1 24 pitch set 4600 WOT RPM

As I thought, the 2.0:1 is the drive they used.
