Not sure what you mean by a turbine ? ... do you mean an exhaust driven turbocharger ?
If so the issues with these is that the turbine only spins up with exhaust power, and that means they are not that good form rest, and you get inherent turbo lag.
If you look at hp / rev graph the curve while it may be OK for a car, is wrong for a boat ... whereas a supercharger has the curve with the power band at low revs where it is needed ... and much flatter ... i.e more even boost.
3-5 psi boost requires almost no engine mods other than supercharger kit, whereas higher boost or turbo charger installs usually mean significant mods ... you can also have an electromagnetic clutch so you can switch on the boost only when you need it.
So if pottering around the bay with Grandma no need to have it running.
GMC 6-71 was one well respected supercharger
Different valves, reduction of compression ratio, re-jetting or upsizing carbs, inter cooler, anti backfire valves, lubrication etc.
If by turbine you mean something totally different, please let us know.
Also as I am not in US ... I know that there is a large 'tune it up' market in US, so you may well have more ideas .. kenn to know what works on a 4.3 .... for my own boat.
