Looking to replace the 4.3 Merc that was in my boat. I've come across a 4.3 Volvo at a good price. Would this be a problem? I still have the A1G2 outdrive...
Thanks!

Strip it down to the long block and put all your merc accessories on it. Yiu could probably sell the VP accessories off the donor engine to recoup some costs .

Block and heads are same GM parts. All others are specific Mercruiser or Volvo.

Make sure you are getting same generation of 4.3. there are 7 generations of 4.3s, and while you can cross generation lines in some cases, it's more work
