I would use the proper eyes as per Don S recommendation. My marina thought they knew better and used straps under the sump and the engine moved off the mounts and slipped forward, smashing the sump through the bottom of the boat. Sump was smashed, so was the inner liner of the boat, but thankfully not the hull.
GM / Merc / VP put those eyes on those positions for one purpose, use them and don't let anyone convince you otherwise!
