I have a 2008 358V , Volvo has just replaced the complete drives with new DPS-A drives.I had the first problem within 6 months from new. one drive was replaced and the other had the UJ gimbal replaced, never ran the drives in any other position than full down, checked the drives March this year found severe cracking/ delamination around the gimbal bearing casting this caused the water intrusion. In my experiance and beleive me i have alot it appears that boats above 29 feet with XDP drives all have problems with the transom shield cracking. THere are seems to be several problem,, the cracking of the transom shields on bigger boats, this seems to happen to 5.7 and 8.1 L enginges, Snapping of propshafts on 8.1 esspacilaly with s/s props, and than running with the drives any more than 20% trimmed down ( bellows failures) than you also have bellows location failures / installation errors. I tested the boat last week with the new drives wow what a differance, better hole shot, runs much flatter, you actually need to trim the drives up about 5/10 % to lift the nose at cruise, seems to have more grip, much much quiter, (through prop exhaust) i can now get on the plane at 15Kts, needed 20 before, and top end 39Kts (GPS speed about 48 MPH) (300HP OSI engines) it appears the new exhausts reduce the back pressure so gives 20 HP per engine more than the 300HP. I had to fight but VP stepped up to the mark, total cost to me, about $1,800.00 for additional hours, cost if i had to pay!!!!!!!!!! probabaly $40,000.00
I can send you pics and further info, VP know very well they have a problem, Rinker,Forumula, Chappeall all have comments /active blogs. One of the biggests problems is if you own a boat with XDP drive and it's above 29Ft YOU WILL NOT BE ABLE TO SELL OR US IT.
Good Luck
