Recommendations for a re-power of a SF23 Inboard?

[blunas2188]

I was wondering whether anyone has ever re-powered a 23' Seacraft center console with a classic inboard set up of a shaft/prop. As of now we are looking to put in either a 225HP or a 260HP volvo diesel. I was curious if anyone has any experience/suggestions or recommendations for this re-power? Also, does anyone know what shaft sizes work best and whether or not a 1.25'' shaft is sufficient. Thanks for your time.
