This is STUCK470 here. Am starting a merc 470 rebuild but 1st have to remove that darn thing. Its been sitting for 21 years and every bolt I touch is frozen in place. Any tricks? I did the WD40, heat up with a propane torch, impact wrench, breaker bar, etc....got to the point where I can now slide engine forward but won't separate from the bell housing. I felt all around and under the bell housing thinking I missed a bolt but looks all clear. Engine will not budge away from the bell housing. I've never been rewarded with soaking anything in WD40 but I'm letting it all hang out here. I'm wondering about some frozen/rusted driveshaft splines??? I mean the outdrive drive line could be holding on? Have a Seloc manual but leaves a cold trail. Thanks for reading .
