3.0 Mercury EFI Solid Mounts/Mid Rebuild- Exhaust mods too?

[Rio Sunset]

Looking to go to solid mounts, and replace all pertinent gaskets bushing etc. while apart. Motor is an 02 with low hours.

Any suggestions on solid mounts? Factory mercury 250XS or aftermarket?

Anything else that should be attended to while apart?

Anyone had luck with any tuners/exhaust mods (ie. hydrotec) on a motorola (single ECM) EFI?

Running on a pad bottom V with seastar Pro (properly bled...) , looking to improve steering response.
