"my motor is a 1994 yamaha 150
"my motor is a 1994 yamaha 150 saltwater series. the fuel gauge failed and i ran out of gas. after refilling, the motor would not get over 4200 rpm at full throttle, made 5500 rpm an hour before. Changed water seperator which was really dirty, checked engine mounted filter which was very clear. Also checked compression, which are all six cylinders low at 105 psi--all exactly the same. I would have thought compression would go unequally between the cylinders, unless something was preventing all six cylinders from making 125-130 psi. Any body have any idea what else can keep the cylinders from getting full compression?
I am no expert at this---appreciate any help. thanks."
