I have finished restoring my 18' deep V with a volvo 280 mated to a 350. I took quite a few measurements and some pictures while doing the tear down. The problem is I am not real confident as to where to place my motor mounts. The idea I have is to put the mounts on the engine and lower it into the engine bay. Then mount it to the transome shield and bolt it up, then line up the engine and mark where the mounts should go. I have a tight angle drill so I can drill with the engine in place. Seems to me this would be doable. I do have the diagram with all the measurements, but I am still not confident I would get the mounts in the correct place. I would be dealing with the real world situation rather than theoretical measurements. What do you think?
