Hello all,

I'm new the forum but have owned my SX190 for 2 years now. I have never really ever got my top speed on my SX190 to get over 35 mph. Each year i have it serviced and winterized. I just put the boat in the water last weekend - max 35 mph @ an RPM of about 6600-6700. My RPM's and speed appear to be good to that point, then I'm maxed out.

The boat has a full tank of gas, 1 person (me 185 lbs), and 2 life vests. Air temp about 80 degrees - located just outside of Atlanta, Ga.

Could this be spark plugs? Gas? ECM?

Any input is appreciated.

I have seen the other threads about removing the ribbon, changing the air filter, etc., but this for now i'd like to keep stock if possible.

Thanks
Ken

I’ve been able to hit right under 40mph with my wife and 3 year old son.
