i've got an '06 2.5 Suzuki. i'm the original owner, purchased 5/06.
i also have the 6 year warranty.
now...regarding the poorly designed cooling system...
- like you, i immediately noticed a minimal flow of water from the two exhaust ports. Suzuki said it was designed that way
- this model does not have a "pee-hole" to check for water cooling
- i didn't have any immediate overheating problems, but rarely ran a full throttle for an extended period
- when i did, i noticed that the motor would steam from the exhaust ports
- after 6 months of ownership, i received a recall notice. faulty water pump design, new components replaced
- during the next 4 years i logged very few hours on motor, mostly at low speeds
- then 1 year ago i moved to a home on the water. i now used the '06 2.5hp Suzuki everyday
- when i travel at full throttle the engine consistently overheats. that is, steam comes out of the two exhaust holes (although water is flowing as well), and the engine dies.
- then after a minute or two, i'm able to re-start and continue on at a slower speed
- bottom-line, this motor is fine if i travel at 1/2 throttle speed or less
the impeller has been replaced twice. once w/ a four blade, and recently w/ a five blade (new Suzuki design for the '06-09).
none of the impeller replacements are under warranty. so i'm to the point that i no longer want to put money into this motor.
hindsight is 20/20, but i've already spent $300 and it still doesn't work correctly.
it is truly a manufacturer's defect, i'm convinced of that.
i can probably sell for $250-400, then go buy a new one for $699 + no tax + free ship on the internet.
that's where i'm at today. stay tuned....
