    Determine where noise is coming from...lower unit or powerhead.

    Lower unit oil was just changed and when this started happening was the next time out.i pulled the plug and didn’t find anything suspicious.checked compression and looked at top of pistons.having a hard time figuring out because it only does it when driving

    Only when in FORWARD, or does it do it in both Forward and Reverse?

    Have you inspected the Prop Hub for damage?
