MS 390 Deck Issues

My wife and I are looking to purchase a 390 asap here in Florida.
We looked at one a couple of days ago, and the flybridge floor was sponge. The entire aft end was spongy and this carried through to the back half of the flybridge sitting area. My question is, is this a common issue with the Mainship? I won't give the boat we looked at a 2nd thought, but it was the 1st boat we've looked at. We're about to drive to the East Coast in 2 days to check out a few more in the 2000 year range, can I expect this to be a concern on the other boats, or was my experience an isolated incident?

On a 2nd note, I'm limiting my look to Yanmars. I would be interested in hearing opinions of single vs twins.

For ease of maintenance I would stick to a single engine. Iíve heard with the twins itís way too hard to get to the outside of the engines.

We looked at a 390 that didnít have any deck issues. So they are out there. I would second the single engine in a 390. I think that twins would be tight for maintenance. Just have thrusters...

390 decks

We have a 2000 390. Have absolutely no issues with spongy decks anywhere. I have twin Yanmar 4LHA=STE engines. The are 230 HP Ea. Have 750 hours on boat. I do all maintenance and have only had to change the exhaust elbows.

Smooth Sailing,
