How to tell if the outdrive is volvo penta or omc?

Answer 1

How old is it/ OMC made an electric shift "knuckle drive" that vented exhaust out past the pin drive prop. Real distinctive as when you hit the tilt it jumped right up level with the bottom of the boat. OMC has pasty white lower units till the joined the 20th century and came up with a nice metallic grey Then a real dark metallic blue.

Volvo has all ways been pale blue. They have a shift rod cover plate(cover) on the top rear of the upper gear housing-held on by 2 big stainless slotted screws.

Hope you own the volvo

Answer 2

The OMC has through the prop exhaust.  The Volvo exhaust at the rear if the cavitation plate, not through the prop.  I hope this helps!
