Mercruiser I assume? where are you getting the replacement engine from? Make sure to put new manifolds and risers on when you swap it out. Don't cheap out and use car stuff

Yes found 2 350 mercruiser complete & outdrives props & all rebuilt guy had bad luck with rotten boat & cut his losses so i have extra parts

i had to redrill my motor mounts as they were in a different location (4.3-5.7L swap) need a long drill bit...

everything else was relatively easy
