Does anyone have any info on the 2003 390 at suncoast boats? Also what kind of speed should a 390 run run with stock 500efi"s

85mph on gps? Really? Anyone know what prop they used in that test?

my 410 did 80 with 540 bulldogs. I imagine speed is about the same with the 390 500hp maybe faster because of weight and surface area

That's a legit speed as I've seen 86.4 on mine in ideal conditions - salt water, 1' chop, 65 degrees no humidity, limited weight and fuel. They likely used a labbed bravo (~30") to plane off like that. You can get a little more top end using a Hydro but it's painful getting on plane - not enough blade area on the Q4. Velocity Tom may have some 390 props for sale.

Definitely a fast boat no bones about it

I think the newer 39 with 565's ran 98-99? I would love to step up to a 39 if i had room to store it.

Driveway for summer paid storage in winter go for it

East pier marina near buffalo has one for sale

What size prop do you run on your 410? thanks for the input.
