Hello. I have a 23' Ragazza that I purchased recently over eBay. I love this boat! It is in great shape except the previous owner got the 350 mag "remaned". I think the mechanic stole his engine and replaced it with a used 5.7L Volvo Penta setup. It feels like it doesn't have nearly enough power. The Alpha drive is in ok shape but if I am going to have to get into engine stuff.....I would much rather go bigger.
I have a 540ci BBC that is set up to run on 89 octane pump gas and has a hydraulic roller setup that is not too wild. It has a great bottom end (forged steel crank, H beam rods, forged pistons etc). I think it should make 550-600 hp.
What kind of outdrive do I need? I don't know if I need the single prop dive or the dual prop drive. What about gear ratios with this weight and HP?? Can a Ragazza handle this much HP?
What all has to be changed out to go from an Alpha to a Bravo??
I don't want to break any speed records...Just have a boat with some pep. I only use the boats in local lakes and rivers. A lot of stop and go stuff.
Thanks in advance!!!
