Pump mount gasket was just to point you in a direction... do not use silicone, a MOFO to get apart and the O-ring is cheap... 
Well thats just great istead of buying rewarders 50$ gasket set i decided to use 8$ sillicone, looks better works better i win, untill i have to take it apart, great.
Alright round 4? I think
Can i check and change valve timing with motor in?
Is it bad to adjust 0 lash valve play by feel?
And is it odd that one random time the boat got airborne and stalled dead in the water when we landed (started right up after)
Is a little blowby normal? Almost looks like a faint steam out of the breathers at idle, checked oil on the first break in run it had a white creamy look to it and im 99% shure its from the assembly lube. Never happened again no water in oil, i did have a problem with the cp performance water pump blockoff plate letting water into the crankcase from where the dip stick is, but i caught it beafore it caused damage. I now use a hardin marine block off plate (the cp performane plate came with the water regulator kit.
Cant really see the motor mounts but can see the front cover pretty good in this pic
