I now own two Perkins 6.354s. One is naturally aspirated 135 hp in a motor sailor that I have owned for 16 years and the second is a 160 hp turbo in the Mainship Mark I that I just bought. Both have slight oil leaks, one at front seal and the other at rear seal. Neither are severe enough to pull engine yet. My guess is that the mainship you are looking at has the Perkins 160 hp. Yes there are some risks to the engine needing work. My guess would be the raw water cooling system components. You might consider investing the money to see if the engine will start. If it starts immediately, it has good compression and fuel delivery (before start attempt would change oil, get fresh battery, change fuel filters, both raycor and on engine, and bleed high pressure pump and injectors which is a real pain with hand pumping the mechanical fuel pump).
