Re: engine alignment
We check alignment any time the drive is removed, for most people it is yearly during winterization. Also, don't forget to reach in and turn the gimbal bearing. If it is rough or you can feel any "Bumps" as it turns, replace it.<br />We even disconnect the shift cable from the engine and make sure it works free and smooth.<br />While you have the drive off, also look at the splines in the coupler. If they come up to a sharp point, you can expect a spun coupler is in your future.
