This is a new Boat/Motor to me. Suzuki 2008 DF-115
Since purchase 2 months ago, the boat will start, idle, and run fine at low RPM's (just past idle). Does not stall at all. Once i get to about 2k RPM, the motor starts to hesitate. Or it's like the RPM's are jumping around like there's inconsistent fuel supply. The problem gets more exaggerated as you increase throttle. In fact, at full throttle, RPM's are just under 4K (barely getting the boat on plane) but will jump unexpectedly to 5500 or so when it seemingly gets enough fuel.
When the motor is warming up, it's the worst, but seems to get a little better as the day goes on. Also, at times I can find a "sweet spot" in the throttle where the RPM's seem to stay high.
So far I've changed the fuel filter, the Fuel Water separator, ran the motor from a 5 gal fuel tank that I know has good fresh gas, and checked for obvious wiring faults under the engine cowling. There are no kinks in the fuel line that I can see.
I feel like I'm headed for the repair shop, but is there something else I can check before I go that route?
Thoughts?
Thanks,
Bob
