The inner and outer bearing numbers you provided and in-line with axles that have a 2,500 lb weight capacity. Therefore, it is likely that you have a 2,500 lb axle or the spindles have been swapped out for a smaller version. The only trailer idler hub we have that has a 5 on 4-1/2" lug pattern and uses an LM67048 inner bearing (1.250")/ LM11949 outer bearing (0.750") is the Trailer Hub Assembly part # DX22XR which has a 2,500 lb weight capacity.

Will these be good for a boat trailer? Will they be sealed good enough? Is there a galvanized option?

@Kevin You are right, those were straight. Looks like you got the only one that has the inner bearing LM67048 and outer LM11949. Just as long as you are not going into saltwater, they will be fine. Salt water is what tends to cause accelerated corrosion, especially on non-galvanized finishes.
