Hot water pressure

2018 Classic 33. Hooked up to city water. Pressure from bathroom faucet on hot water about 1/2 that of cold. Pressure at galley faucet ok. Both under sink water valves fully open. The only way to get good hot water pressure at bathroom is to also run water pump. Pressure was fine last fall before winterizing. Any ideas?

Sounds like the faucet has some trash or scale in it at the mixer, you may have to take it apart and clean it or replace it. Could be the block valve under the sink or the tubing that that is uncommon.

Every time I dewinterize I have to take the faucets apart and clean out the scale. Usually the screen in the outlet is plugged.

Another possibility is that the hot water mixer on the back of the hot water heater has a scale buildup. That happened to ours and I had to replace it.
