I've been trying to slowly restore my 91 3.0 mercruiser alpha one. I've gutted it completely, now I've put the motor back in and I'm having trouble aligning it properly. I bought the tool but when I bought it he boat whoever "attempted" to fix it half ***ed it completely. Missing parts. Wrong parts. Etc. What is supposed to go on the rear of the motor for the motor mounts. I've researched it and there seems to be numerous ways ppl have done it. So any help is appreciated!!! It's a 115 hp btw.
