Internal cooling passage corrosion is the primary failure mode on saltwater engines and may not be visible from the outside — inspect passages during annual service.\u003c\/p\u003e\n\n\u003ch2\u003eParts Desk Insights\u003c\/h2\u003e\n\u003cp\u003e\u003cstrong\u003eBest Use Case:\u003c\/strong\u003e R029011 is the correct OEM replacement for Crusader and PCM inboard owners replacing a failed or corroded 3-1\/2\" exhaust riser on GM 350\/305 or Ford 302\/351 applications. It is particularly well-suited for high-hour saltwater engines where internal cooling passage corrosion is the primary failure mode, and for owners performing a full exhaust system refresh alongside manifold replacement.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCommon Customer Issue:\u003c\/strong\u003e The most frequent ordering mistake is confusing R029011 (3-1\/2\" outlet) with R029001 (3\" outlet). Because the same PCM manifold can be found with either riser, measuring the existing exhaust hose connection is the safest way to confirm the correct part before ordering. Ordering the wrong outlet size results in a hose fitment problem that requires a return.\u003c\/p\u003e\n\n\u003ch2\u003eRelated Products\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\u003ca href=\"\/products\/mps-1\"\u003eCrusader Riser Gasket — REC96562\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"\/products\/crusader-12\"\u003eCrusader Exhaust Elbow — R029016A\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"\/products\/crusader-center-riser-cr-20-98126\"\u003eCrusader Center Riser — CR-20-98126\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"\/products\/crusader-exhaust-manifold-302-351-r028001\"\u003eCrusader Exhaust Manifold 302\/351 — R028001\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"\/products\/crusader-exhaust-manifold-6-0l-r028024\"\u003eCrusader Exhaust Manifold 6.0L — R028024\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"\/products\/fairview-197\"\u003eCrusader Exhaust Manifold Gasket — RM0007\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"\/products\/fairview-198\"\u003ePCM\/Crusader Exhaust Manifold-to-Cylinder Head Gasket — RM0276\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CRU","offers":[{"title":"Default Title","offer_id":43563780735012,"sku":"r029011","price":234.53,"currency_code":"CAD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0743\/5799\/7604\/files\/7508b3a2-61fd-457b-b5bc-de90cdc8019d.png?v=1787448900","url":"https:\/\/marisolmarine.com\/products\/crusader-pcm-exhaust-riser-3-5-inch-r029011","provider":"Marisol Marine Company","version":"1.0","type":"link"}
