Ive got a little vibration when im running along slow to mid throttle. The outdrive was completely rebuilt before I got it. The U joints and all were replaced. I rebuilt the engine, engine bed stringers and transom, installed engine and lined it up using a merc alignment tool. It slips in really easy, so i believe it is correctly aligned. Could the imput shaft be out of balance? I can trim it up when it gets up on plane and it smoothes right out. If I trim it back down it grumbles a little. Forgot to tell ya I rebuilt the whole gimble section, new gimble brg. boots, hinge pins,top and bottom swivel pins and brgs. What do ya think, it feels like the imput shaft is out of balance or something. I dont want to screw up what Ive already done!
