Re: I have a 898 mercruiser going to use volvo penta exhast manifolds
What do you mean by a few mods? Do all the hoses from the thermostat housing fit? If not you may need to replace the thermostat housing. I had a merc 898 on my Checkmate and I switched from log manifolds to center risers and I had to change out the thermostat housing to the newer type with the T valve.
