1. A/C Unit Problem

Your A/C unit might not function properly due to the lack of water within the system. This is a common problem faced by a lot of Sundancer 280 owners.

The problem also can happen due to the engine. The mercury engine can hamper the power delivery of the boat system as well. hence, the engine outboard crank won’t start.

Moisture problems are seen in the older models mainly due to the design and structural limitations. Besides a damp and dirty environment within the boat could also create this problem.

Moisture attracts the growth of mold and algae. This makes the boat lose its strike condition and ruin the entire structure.


Once mold growth starts, it cannot be fixed just by simple cleaning. It’s a long tedious process that includes a lot of work. You’ll need to get your Sundancer 280 to a dry dock and then thoroughly clean the entire cruiser.

As well as, you will need to replace all wooden and any organic parts from it. Only by taking these actions, you can save your boat from constant mold infestation.

From then on you need to keep your boat moisture-free at all times. Especially if it’s an older model.

3. Instability Problem

This instability happens due to the model having the wrong tabbing trims installed. Also, this might occur due to the handling not being tuned properly.


If it’s a problem with trim tabs, then you’ll need to inspect the outdrive trims. If they’re misaligned, then adjust them and the weight distribution of your boat to fix the balance.

Now if this problem arises due to the waves, you need to better control your boat. You can use lube the steering cable on the boat as well for better access.

4. Hull Problem

Instability Problem

This is rampant among the older versions of the model. Due to age and poor build quality, the hull of the boat gets damaged. The joints get rusted and leakage may start to happen.

Also, the fiberglass shell could form cracks and eventually shatter on impact with large waves. This problem makes the Sundancer 280 very risky to use. Moreover, it can even have a negative effect on the buoyancy level of the boat as well.


The best solution would be to contact the manufacturer. They do have the service to repair or replace the entire hull for you. But they do charge a lot and it can be costly work. But this is the best option you have for now.

Another option is to repair it with the help of your local shipbuilders. They can replace the hull or might do structural patchwork. This is done by patching the crack using the best and strong adhesive like marine tex and jb weld.

This depends on the condition of your hull. They can be a lot cheaper but you’ll have the risk of not having the job done properly
