Suzuki DF350 #'s
So I'm almost finished with the first 10 hrs on the engine and figured i'd post up some performance numbers on the Boat/Engine. I'm very happy with the performance of this engine and the 23 seacraft. I hadn't ever ran one before i pushed mine off the trailer and fired up the engine. I think it may benefit from raising the engine up to the last hole on the bracket and may need to go up a prop size after the rings fully seat but I really dont think it's worth the expense of 2 new props for a small gain.
1979 23' SF - Suzuki DF350A Prop: 15.5 x 24 duoprop Mount: Hermco Twin engine bracket mounted 1" higher than instructions (top of platform 27" above keel) Fuel - 90 Gallons (104 gal tank) 90 Octane ethanol free Weather: Glass calm conditions, 90 degrees 5 adults and minimal gear, T-top installed 3300 RPM - 30 MPH - 7.93 GPH - 3.8 MPG 3900 RPM - 36 MPH - 10.3 GPH - 3.5 MPG 4600 RPM - 43 MPH - 15.0 GPH - 2.9 MPG 6300 RPM - 59 MPH - 29.8 GPH - 2.0 MPG Whats interesting, is that with 20 gallons of fuel and only me on board i get the same Max speed of 59 which is what leads me to believe it may need more prop. |
Sounds like a nice sled. Sounds like there is a little more in it yet maybe. No bad #'s at all.

Let's see here, 30 mph at 3300 rpms at 3.8 mpg....with five aboard??? I would be ecstatic!!! Well done :)
|
Those are some outstanding #s for sure.
|
350
How is the stability and how does it go in reverse
|
Sweet! I need one of them 350's
|
3900 RPM - 36 MPH - 10.3 GPH - 3.5 MPG with that load is amazing!
|
Great numbers! Where are the pictures? So I guess a spare prop means both?
|
incredible numbers! bigger is better!
|
WOW! Same MPG or better than my '79 with a new 300. And you are pushing 60 which is crazy. She's about 6mph faster across the board at the same rpm's.
Tempted!!!!!!!!!!!! |
350
How does she perform in reverse. I talked to a guy thatAdd a 300 on his boat and changed over to a 350 and said With the duel props reverse was much better control

Engine height
Sweet boat. I just put a 300 Suzuki and bracket on my 23 and fighting a porposing issue. I was wondering if you had any issues and how many inches between you AV and keel. Any info would be a great help. Thx Keith
|
how much is the cost differential 300 vs 350?
the performance is pretty nice it seems..

you may also want to check for a hook in the hull with a straightedge on the keel. |
Has anyone bolted a 350 ( or motor over or around 700lbs) up to just the transom, no bracket?
On a 23 |

|
