i have a 1985-86 omc cobra i need a template to cut the hole for my outdrive
i am having trouble finding it ,i was told it is the same template as a volvo sx
drive,but i need to be sure before i cut my newly built transom.

also any info on the process of finding where the leg should be from the bottom of boat would be appreciated!

Post a picture of your drive. Cobra's didn't exist in 85

Re: cut out template

Use the template and cut out the opening from a scrap piece of plywood and then see if it fits.

Have a great day

Rob.

Yeah....it's the same. It'll also work for a Mercruiser.


Cheers,

Re: cut out template

aloha ! i got the template and did the measurments based on a 15 degree
transom angle,14 3/32 " from boat bottom,this will put the av plate level with boat bottom,but the template says optimum is 3/4 in above bottom?
if i raise it 3/4 in it would work out perfect because my drain hole would clear the shield ,but i was wondering if the 3/4 in would cause ventillating
thanks Tom
