2002 Sea Doo Sportster Clanking Sound?

[seadoosportster2002]

Recently purchased a 2002 Sea Doo Sportster LE jet boat with the 947 Rotax motor and my third time on the lake (after about an hour and a half of riding around) I started to hear a "clanking sound".

Running with a hose on the trailer:

Concerned that there is probably something needing to be fixed before I go back out on the lake.

New to this, any help is appreciated!

Running on the hose tells me nothing. There's no load on the pump or engine.

Put it in the lake, and then post up again.

I did a compression test with results coming back at 120 on first and 70 on second.

Should I just do a swap or something with a complete rebuilt engine?
