Banging noise

[wicked salmon]

We have a 89 prohunter that makes an intermittent banging noise. Happens when we are at full speed on plane not when trolling. Also seems to be weight related since its happens when the tanks are full and 3-4 people are on the boat. Any ideas?

You better check up on what those 3 or 4 people are doing.

If its engine related we need more engine info. Generally the boat make does not matter and probably half the people on here, including myself , are not up to speed on all boat models and what power train they have. If it's some non engine sound or drive train sound then pull a hatch cover or two while it's happening and narrow it down. Loud banging sound with a load or higher speeds in many cases is a rod knock.

Do you have bumpers hanging out over the side when running?
