The engines are on the back of a 2001 G/W 265. The boat is a single owner boat and the dealer who is selling it sold it new and has performed all of the maintenance, so they have the complete maintenance records for the boat. The boat is in decent shape, everything works, it just needs some updating on the electronics and soft goods. I will of course have a survey performed on the boat and engines if I decide to move forward. Based on the information available, the 200 HPDI perform better than the 225 4s on this boat. So I want to be able to keep them as long as possible. The other reason I want to keep them is that this boat was not designed for the added weight of the 4s and I would have to raise the scuppers if I replaced the HPDI's with 4s
