Installation Guide

  1. Safety First: Disconnect the boat's battery and ensure the engine is completely cool before starting.
  2. Access the Area: Gain clear access to the sterndrive's exhaust components. This may require removing drive components or panels.
  3. Locate Old Bellow: Identify the old lower exhaust bellow connecting the exhaust elbow and manifold.
  4. Remove Clamps: Loosen and remove the hose clamps securing the old bellow at both ends.
  5. Remove Old Bellow: Carefully pry or cut the old bellow away from its connection points. Clean the surfaces of any old adhesive or rubber residue.
  6. Position New Bellow: Slide the new exhaust bellow into place, ensuring it is seated correctly on both exhaust components.
  7. Install New Clamps: Place the new stainless steel clamps over each end of the bellow.
  8. Secure Clamps: Tighten the clamps securely to create a watertight seal. Do not overtighten, which could damage the bellow.
  9. Final Check: Once installed, double-check that the bellow is straight and not twisted or pinched.
  10. Reconnect and Test: Reconnect the battery. After reassembly, run the engine with a water supply and check thoroughly for any exhaust or water leaks around the new bellow.

A: The best way is to check your original part number against our cross-reference list, which includes OMC 3852741 and Volvo Penta 3863450.

Summer wedding kids suit
Color: Navy, Size: 10 Years, Color: Navy, Size: 10 Years
Bought this suit for my son in the 10 youth size and honestly was pleasantly surprised by the quality for the price. The navy color looks sharp and dressy without being too stiff or uncomfortable. The material has a little stretch, which helped it fit nicely and made it comfortable for him to move around in. The adjustable waist was a huge plus, especially for growing kids. It fit true to size overall, though the blazer sleeves were slightly long on my son. The pants had a nice slim look without being too tight. We paired it with white sneakers for a more modern look and it came out adorable. This would be perfect for weddings, graduations, concerts, communion, school events, or family photos. Overall, very happy with the purchase and would definitely buy again.

Very Modern Handsome Suit
Color: Grey, Size: 7 Years, Color: Grey, Size: 7 Years
This is an incredibly sharp looking suit for the little guy. Great price and features, too. I made a mistake in sizing up instead of down and first one was too sloppy on him and would need alterations. He is thin and very thin in the waist. There is a lot of adjustment with buttons in waistband and coat hides the bunching. This shirt and coat will easily take a fuller body than slim I believe. He loves posing in it and feels very classy. Best purchase for a formal suit that will last longer than most kids clothes size wise. Felt bad about returning but careful folding and packing got it good as new.
