1992 mercury, 75 horse, serial # 0d165408.
Boat sat for 2 years, Im amazed at how well it cleaned up and then fired up and runs, I did all the obvious stuff cleanining, gum out, seafoam etc etc, Now it idles great, takes off great and runs great up to 3100 rpms, thats it, doesn't stall or spit or backfire, just won't go any faster than 3100rpm,
If I put it in N she will rev as high as you want.
Rebuilt fuel pump,checked all the lines for blockage, disconected lines and squeezed the ball and got good fuel pressure all thru,
I was hoping I wouldn't have to take the boat out of the water which I would do to remove the carbs, and there is my question, Are 1 or more of my carbs trashed?
Thanks in advance guys,
Sincerely razzor
