Parts Desk Insights
Best use case: The 3" x 3" Minimax is the right choice when your exhaust system uses 3" hose and space in the bilge or engine compartment is tight — common on smaller inboard ski boats, runabouts, and compact V-drive builds. If you’re deciding between the 3" and 4" Minimax, match the muffler to your existing exhaust hose diameter; upsizing or downsizing the connection will require reducers and can affect back pressure. Above-waterline installation is required — this muffler is not rated for below-waterline or wet exhaust applications. Contact us with your engine make, model, and exhaust routing details if you need help confirming the right fit.
