i Understand that this is the lifeline to my motor ...does anyone have a schematic on which poles on the plug are supposed to be hot ..in and out so i can start checking

They have the electrical schematics here inside the manuals:

this is what the fuse looks like. It mounts to the stud on the starter. If you have no power at all to the dash etc...this is more than likely your problem I would say

So after i searched for fuse on starter and got a picture ..i called myself every name in the book..Checked for power on both sides and deffinatly needed a fuse the 90 amp on the starter like everyone has told me...I was looking for a bus mini fuse ...the helm gets its power throught the harness on the back of the engine and then powers up the rest ..Thanks for all the help ..and the above info is the correct picture

Glad you got it going. Down time is the worse!

I speak from experience....I just had the same situation on my boat and it took me a few hours to trace it back to that fuse. Glad I could help.
