Have: 1994 150HP V6 60 deg loop charged engine
model# E150GLERA
Engine is running normal, however there is a "mystery" chatter that becomes audible around 2k rpms. Chatter is erratic and not rhythmical...can not hear it at idle in water or on muffs...
Had a mechanic bud river test w/ me and he deduced Lower unit starting to go bad...swapped a new "used" lower unit in...same chatter.
Wondering if perhaps chatter is coming from a bad reed valve. have checked flywheel and swapped out fuel pump/vro (vro is disabled w/ premix on this motor)
I realize that reed chatter is normal on the engines when backing off of throttle...thinking of putting boyesens in, but before said expense wondering if anyone has any ideas on this one.....thoughts??
tx in advance
