Looking into buying a Wellcraft 210 Coastal with a 2.0 Liter Sea Drive. Unit has a new powerhead & runs smooth. Looking down the road a few years, I plan on re-powering. I have heard that you can mount a new Johnson/Evinrude motor to the existing Sea Drive bracket instead of installing a new gil braket. Is this correct? Any comments on the Sea Drive performance & reliability? Thanks?
