Danny, Lets hope it's not the prop. You've got a 50/50 chance it's installed correctly. I'd continue the engine shaft alignment process and see if the vibration diminishes or goes away. However, if the vibration continues, it could well be the prop. Most folding props are balanced by the manufacturer. When balanced, the manufacturer should stamp a small mark on one blade and on one side of the hub. To maintain the balance, the blades should be installed in the hub the same way as when balanced, i.e. the marks should line up. If the blades are swapped, imbalance, and thus vibration, may result. You may be able to check the marks underwater with a strong dive light. If not, you can remove the prop underwater, check the blade marks, mark the hub and blade with tape for visibility and re-install properly.

If so, were there alignment marks on one blade and the hub? Were they matched?

The engine runs nicely but, it vibrated like crazy underway. It appears I did not align the engine. I've gotten it better aligned now but, are there any tips or techniques to adjusting this thing to get dead nuts aligned? It seems a very tedious endeavor... When I put a dial indicator on the shaft, just aft of the coupler, I can't seem to get it better than .005 of an inch. It started out at about .015 when i first put it on and i thought that the .005 may have been acceptable but, it still vibrated. I've asked the yard mechanic to have a look and align it for me. However, if he doesn't get to it this week I'd like to get it done myself before the weekend so that I can FINALLY go sailing!
