I bought a 1977 Sea Ray srv 240 project and plan on using a newer Alpha. Couple questions. The drive I got is a 1.84, and I've heard mixed opinions whether this will work. Can a prop make up for gears? I bought a 14.5x17" stainless. It is a big heavy boat so I heard these gears may be right. Secondly, I plan on buying a 260 LX mercruiser thats blown but has all marine parts for my vortec longblock. It had a Bravo though, so will the bellhousing work with my alpha? More importantly, how about the flywheel and coupler? I have an alpha bellhousing so if only the coupler worked that would be a bonus. Thanks in advance.
