Started about a month ago any time i would take off my boat wouldn't go any where b4 i rived it up in neutral seemed kinda like it wasn't getting any fuel but ones i rived it up one or two times it would go at full speed all day till i slowed back down so over the next 2 or 3 times i took it out it got worst and today it just don't go over 2,000rpms full throttle in or out the water checked my fuel the pressure builds up slow but it gets up to 90psi injectors are all good just wondering if any one has had a similar problem...and what it was?
