I have a fleet of three boats with two engines each.
they are fairly new.
I have a problem with three motors all at the same time, two on one boat and one on another.. Above 2,500 RPMs they start to vibrate and the pilot is obliged to reduce speed to under 2,500.
I have changed the plugs on one, but it has made no difference.
Has anyone got a solution to this please?
