Does anyone have the cam specs on the merc 540 and 565 engines?

How s this

Let me know if you can open that

I think he is looking for the new 565 motor

👍👍😊😊

Thanks for the reply, I should have specified though.... I meant the new EFI Engines.

Link Worked FWIW

Veloc410 is probably old as dirt like myself because that's the first thing that came to my mind as well. Bulldogs.

The reason I am inquiring is because with 2 engine packages so close in power I bet the in boat performance is quite different. The 540 is 522" 4" stroke and the 565 is 533" and 4.25" stroke. Curious to see if Mercury increased the duration considerably in the 565 to compliment the stroke. From my research it seems like there isn't much known about these newer EFI power packages yet. I'm 50/50 on my new builds going 4.25" stroke or building a large bore 4" stroke. I wasn't wanting to go tall deck so the 4" stroke is very appealing. Just curious as to how Merc views the difference in stroke and valve events.

I dont know the specs but mercruiserparts are showing the 520, 540, and 565 all use the same cam
