Re: Volvo Penta engine change
You do not have to remove the complete outdrive on that style outdrive. Only the upper gear box. Here is a drawing I made to show how to remove the upper.
Once you have the upper gear box removed, you have 6 bolts that hold the clamp ring on (They have locking tabs that have to be straightened out).
Once those six bolts are removed, you can pull the engine and flywheel cover out as a single unit.
PS: You do not have a gimbal bearing, nor do you check alignment on your setup.
