i bought a boat with a seized 350 in it last season. prop turns by hand in F, R and N. in the last few weeks pulled the engine and swapped the block with a truck engine. it turned over by hand prior to installing it back in the boat. i have never aligned/installed an engine myself before but it seemed to go pretty smooth. i got the bell housing bolts lined up pretty close and then with some slightly longer bolts i pulled the engine in little by little by just turning each bolt a half turn (rotating evenly through all the bolts). there was never any friction and the engine just slid into place. The bolts for the mounts were totally rusted out so i haven't bolted them back into the stringer but they are resting on the stringer. when i tried to turn the engine over by hand it is frozen up somewhere. up to this point i haven't known if my outdrive works or not. i pulled the upper gear unit and tried to get it out but am having trouble sliding it out all the way. i can see a lot of rust under the bellows. the upper unit turns 360 degrees but won't pull back. at this point i assume the engine won't turn over because something is frozen in the outdrive? does this sound correct? or is it possible that i have an issue with the alignment of the engine to the outdrive shaft?
any thoughts on what i should try next? continue trying to get the upper unit pulled free? disconnect the engine again and slide it back on the stringers?
