Corroded, weeping exhaust risers on both engines
“The port and starboard exhaust risers show heavy external scale and weeping at the manifold joints; recommend replacement.”
- What it means
- The risers carry hot exhaust and cooling water out of each engine. They're crusted with corrosion and leaking at the joints, so the surveyor recommends replacing them.
- Why it matters
- Corroded risers can let water back into an engine, which can ruin it. It's a known wear item on gas inboards, especially in salt water.
- Next step
- Ask the seller to replace both sets before closing, or to reflect the cost in the price. Have a mechanic check for water in the cylinders.
How we estimated this
- Both engines' manifolds, risers and elbows; seized bolts can add labor.
- 2 engines
- Gas V8 inboard or sterndrive
- Shop installs aftermarket or OEM cast parts
- Seized bolts and access raise labor
- Estimate only, not a quote. Confirm with your surveyor or a qualified yard before you act on anything here.
