Still curious if anyone has seen an OB conversion. I really like the size, speed and price of the 400ss. But I’m leery of saltwater inboard use and bravo life. Trip 300s, 350s, 425s? Could be a good running boat. I recently looked at an intrepid 400 cuddy that was a $450k ask for a 2016!

I don't know of any O/B conversions and I follow lots of Formula pages. Knowing how these boats eat Bravos I found a VP diesel version. The drives are HUGE compared to Bravos and seem to hold up well. We certainly love our 09 400ss!!

Is this a 400ss outboard conversion on the left with quad 400s? Sure looks like a 400ss trunk lid, arch, interior, etc. 🤷‍♂️
