Can someone provide me the timing specs at idle and max for my 1987 45hp (4 cyl) 2-stroke Mariner engine please? I'm waiting to order a service manual and would like to check all my timing marks.

Can't help you. I thought this Mariner might have been made by Yamaha but apparently not. Good luck finding the data you desire.
