I finally finished putting the engine back together with freshly bored cylinders and new 30 thou oversized pistons, and got the corroded/cracked section on the base of the block welded and machined flat.<br />Since this is the first time I have done this with an outboard I was surprised I actually used all the bolts in reasembly and actually managed to missplace/lose only two---one for the head plate cover and one for the the block to base mount---don't ask me how I managed to lose THAT one since it was one of the biggest bolts on the engine!!!!<br />Anyways in my excitement to start the motor I went ahead without these two bolts and the engine started fine with what seemed excessively high compression---170psi in each so that I had to jump the starter battery with my truck to get the darn thing to turn over!<br />But when I shut it down and checked the plugs...the bottom cylinder defintely was taking water AGAIN!(well steelespike, now you can say "I told you so!" :( :rolleyes: ). <br />So I went and bought a new base mount bolt and after torqing it in, I realized I forgot to fully torque four of the other block base mount bolts. I breathed a sigh of relief...hoping this is why the water was getting into the bottom cylinder, but I couldn't find out because the engine wouldn't restart!!<br />After pulling my freaking hair out for a couple of hours trying to figure out why, I pulled the flywheel and guess what....SHEARED KEY!!!!!!!!!! I didn't torque the flywheel enough. So now its too late to get another key till tommorrow, and my question is will the missing block to base bolt and under-torqed block to base bolts let the water through to the bottom cylinder or will I have to take the whole thing apart again to find another crack somewhere in the block?<br />Thanks, and I'll let you all know the outcome....

Don't pull yer hair out stinkpotter,,we all been there at some point in time. Definitly get the missing bolt replaced. Before starting again, get another compression reading. Should be ok. Don't forget to re-torque heads after warm up and cool down.<br /><br />OBJim
