Is there a plate for the outrigger mounts already welded into the T-top? If so, make sure whatever mounts you get will pop into that hole. Otherwise you are going to have to get a new plate welded in. Not that it is a huge deal, it just makes a quick project into a more involved project.
I had Taco Grand Slams on my 2002 273 Chase, and they worked fine. I had to retract the telescoping outriggers after each trip so my marina could put the boat in the stack, which was a real pain.
Be careful with those engines. My 2002s had the exhaust work done before I bought the boat. That did't stop is from blowing a head gasket and needing a complete rebuild. Those 225s ran great until that. It happened right around 500 hours. Assuming they scope clean, you can use their bad reputation as a bargaining tool and then run them till they die and re-power. Just know they are nowhere near as reliable as the 250s.
I loved my Chase. It's a great boat. Plenty of seating for cocktail cruising, plenty of space for hauling the family to the beach, and a very capable offshore platform.
Good luck!
