Last year with only 40 hours my new 250 Suzuki was starving for gas at 5800 rpm. Motor would run great but at WOT after 30 sec motor would back down at 4000 rpm. Never stalling. Just backs down to a lower rpm. I don't run motor at WOT but when I do I only do it for less them 1 min. I started checking vent- pulled the gas sending unit out and checked gas tank. R&R 10 M filter. Still having problems. I took the boat to a Suzuki mechanic. Got hit with a $800 bill. They check the tank. All good. Vents. Replaced the gas line from tank to motor. Replaced the primer ball. Replaced the gas tank valve. Road tested and still having problems. The motor is not over rev. rpm. She is at 5800 wot. The mechanics replaced both primary and secondary filters and problem fixed. This year I put boat in water and problem started again. Now I'm going to order the two filters in motor. I did go 600 miles and over 200 hours since last year. Hoping the filter fixed this problem. Is this normal? Are those Suzuki filters that sensitive? I always use addictive in the gas.
