Hello all, new to this site, and needing a little help.
I have a 72 55 horse, and am trying to smooth out its performance, I have a manual and I am mechanically inclined but havent worked on out boards.
My main question is because my motor does not have timing marks (the manual confirms some dont) I evidentally must use a special tool refered to as (T-2937) which screws into the number one cylinder and has a rod (with marks) on it which are used to find 28 degrees BTDC. I dont have one and cant find one so I decided to make one easy enough but I need to know the placement of the marks at the 40 horse end of the rod.
If any of you have one could you please measure the placement of the first and second mark on the rod from the end.
THe motor runs well but idles rough, compression is 140lbs, and it is my understanding it was stored much of its life, none of the bolts have been turned i.e. the paint is still perfect, so I read earlier that I can get a Fuel pump and Carb kit from NAPA so I will do that but I want to ensure that the timing and all linkages are correct, and, apperently to do that I need this tool (T-2937).
If anyone has any info, or suggestions please respond. Thank you and good boating.
