I have heard about high maintenance cost, how about your lift system?

We have a very low maintenance cost because we have the hole lift system above the water. Solutions were the mechanic is under water, and specially in sea with water temperature above 25 degree Celsius, it grows lot of seashells etc. That needs to be cleaned away often to keep the system working, which only can be done by hauling out the boat from the water or by using divers.‍
