You'll probably need to take the boat to the dealer. If you are comfortable working on engines you could try and diagnose it yourself.

If there was no oil on the dipstick the engine should be checked with a boroscope and a leak down test done to see if there was any damage to the engine.

Can you take a picture and post it of where the oil was leaking from?
