Hi everyone, I recently got a V20 1986 dualC

Add to your signature your location, year of the boat, motor type, size and year. This will help us to quicker diagnose problems.
As always, pictures like you planned.
Being you got a Merc, if one comes available near you, with interchangable parts, you got a headstart. If something else pops up very cheap, then that might be the best way to go.
If you do find a suitable motor, insist on seeing it run and do a compression check. Most everything after that should be easy.
Post questions (and pictures) as you go, this will save you time and money.
