Have voluntered to help a woman out with her motor so she can get out fishing again. Looked at it this morning and found out it was an abandoned attempt to replace the rubber motor mounts. Guy working on it walked away a few weeks ago. He had tried to pull the power head as well as drop the leg. Its a saltwater motor with seized and broken bolts. From what I can tell he might have been removing to much.
From what we can get off the damaged metal tag, 040PLRS, nbr below that is definately 332750. Older 40 YAMAHA 2 stroke. No tilt or trim or oil injection. Question is, how involved is it to replace the 4 motor mounts? Looks as if the bottom mounts will require the leg to be pulled back and new rubber slid in ( already have the big acorn nuts loose, no problem there). Big question involves the upper mount bolts. They are not going to move. All the rubber around them is gone so it will be simple to cut the shank and still leave enough metal to heat, tap and get a small pipe wrench on. Will I have a problem with clearances when I go to install the new upper bolts? They are pretty long. Want to avoid trying to remove the power head and transom bracket if I can ( corrosion).
I am doing this for free but dont want to get the thing apart and tell her I cant get it back together. She is a bar maid at the legion hall so I expect to get a few beers for this. Hope I have been specific enough. Will add that the boat is on a trailer so I can use one of my davets to handle the motor. THANKS FRED

best I recall the C40PLRS has to have the powerhead removed to access the upper mounts.

RODBOLT, thanks for your reply. At this point there is nothing to lose by pulling the power head. Have had mixed results with the bolts on these old salt water motors. FRED
