Sundancer 268 prop?

[AJ Heuvel]

Hi there just bought at 89’ 268 with 7.4 454. I was curious what size and pitch prop people are running to maximize fuel and speed. TYI

Had an 89 268. Don’t remember. Long time. Mine was factory stainless.

I put a stainless mirage on my '90 270. 15.5 x 17 if I remember correctly, replacing a 14 x 19 aluminum which was pitiful. I'm very happy with the performance.

Your signature mentions that you have a Bravo III drive. That's going to be a VERY costly endeavor to change those props. Unless the current performance is WAY off, which is unlikely, it will most likely take you a long, LONG time to recoup (in fuel savings) the money you spent on props.

But, before you even consider changing props, use the boat for a while. Do not consider changing props until you get quite a bit of time behind the wheel.

Also, what's your current performance like? GPS speed and max RPM fully trimmed out.

Best performance I could get was the 16x16 aluminum prop. Mine was an '88 with the 454 and Alpha drive.

Top speed was 32mph.

Yours must have been converted to the Bravo III. I believe the Bravo I came standard on the 89's. I'm not sure which prop would work best for you with that setup.

Agree with @Getaway
Are you sure its a B3? the B1/B2 are still a "Bravo" but a single prop, the B3 has the dual propellers.
The B1 for your year was a 17" Mirage @ 4600 RPM WOT

According to the Sea Ray Prop charts the first year B3 were offered with a 7.4 was in 1993 on the 270WE/DA that called for a 22x22 @ 4600 RPM WOT
