Hi there . Ive got twin 300 Etecs and when I tilt down the motore they shudder and bounce like crazy , Ive greased all the lube points and no difference . Could there be something wrong internally , any ideas ?
Sounds like you have something binding up in the tilt tube area even though you greased the fittings. You may want to call BRP customer service at 1-262-884-5993 and see what they have to say.
