Is the footprint of an HPDI the same as an OX66? I found a decent, low hour 250 HPDI for sale and I'm tossing the idea around of upgrading. I'd like an F250, but cost and the mount being different is making that kinda hard. I'd need to get pull the OX off, get the transom filled at the fiberglass shop, then hang the 4 stroke on it. The HPDI is the next best thing.
