Long story short I'd like feedback/guidance on relay selection. The relays will be used to operate reversible ballast pumps.

12v pump, stated draw is 11.5 amps. Its on a 20 amp circuit breaker.

The relay needs to be waterproof/marine grade, continuous duty and handle 20 amp start up surge.

This appears to fit the bill, would it work well?

Do I need something heavier duty?

Any other suggestions for relay?
