I made the jump for outboards, transom holes closed this Saturday, bracket will be installed Monday and by the end of next week I will be running a pair of Zukes 300. Couldnt deal anymore with upside down maintenance.

Coming right along! Since this is a 280, twin 300's should be nice. The OP's boat was a 330 and not sure if twin 300's would be adequate.

330s came with 330hp 454s, 310hp 454s, and even 350s which I’m guessing were around 300hp.

Mine runs 58 with 330s. It will run great with 300s.

Mine had twin 5.0 mpi (260 hp each), wot was 50mph.

You might be right but I have my doubts on 300 OB's on a 330. It's not all about HP, your 454's will have waaaayy more torque not to mention more bite with duo-prop I/O's.

The smallest OB engines Formula offers on their 310 Sun Sport is twin 350 Verados.

They won’t have as much bite as B3s, but zukes have very big wheels on them.

OBs tend to run better HP for HP due to either the cg being further back and or the X dimension being better.

I also have a 35’ CC with twin Suzuki 250s that runs 52.

Been talking about doing this to a friend of mines 06 330ss. What is the plan for the space/abandoned engine compartment? Leave as is/storage?
