If I install a rail kit on my boat would I need to get a new drive shaft?  I have a 4 point mount right now.

Depends oh what you have now, I run a 1350 style drive line u joint set which Is borderline overkill for my set up. A 1310 would be a step up from what you probably have. But more then likely what you have now is more then enough unless your up in the 7-800 hp range. And inland drive line, Je reel, and any 4x4 shop can get you the joints. Do not get the ones with zert fittings they tend to be a lil weaker.

I usually go through inland drive line.

If you're switching to a rail setup from 3 or 4 point, and you're replacing the u joints or whole double cardan joint, make sure before you set the system in stone that you measure and set the driveline angles. You'll prevent a major common vibration issue.

Buy the u-joints. But when you're setting the engine in, before you drill holes in the stringers, use an inclinometer to ensure you have at least 1/2 to one degree of working angle and that both joints are within 1 degree of each other.
Nothing would suck worse than do all this hard work, just to ride the water version of the Home Depot paint shaker.

Inland driveline did mine for me

Excellent question , why did you move the engine so far forward?
