Ocasional RPM loss

[oldcobia]

Have twin 2001 250 2 strokes. Ran great last year but sat for about 4 months. New gas put in tanks. Starboard ran great. Port also did great for about 30 miles at 4200 RPM. Then got occasional RPM loss in port engine too around 3200 RPM for a few minutes then would go back to 4200. This happened about 5 times in 15 miles. Back at dock all gas drained from filters were spotless and have been for the last year. Filters only have about 150 gallons through them. Is it sill possible that the VST filter could have a restriction?

from what I have read the VST pump screen and injector screens plug up with brush dust from the pump motors, so yes the filters before the motor will not catch that stuff as it does not go thru them

Drain the VSTs into a clean container and inspect for crap and water. You can also blow back thru the hose to loosen, drain more crap if need be.

Squeezing the primer bulb will also push fresh fuel thru..

Can you get FULL WOT RPM's, (5,000-5,500 RPM's)?

Is the VST filter 150 hours use also?
