Installation Guide

  1. Drain the cooling system: Open the drain plugs and allow coolant to empty into a suitable container.
  2. Remove old hose: Loosen existing hose clamps and carefully slide the worn hose off the pump and engine connections.
  3. Inspect mating surfaces: Clean any debris or old gasket material from the flange mounting points.
  4. Position new hose: Align the fixed flange hoops with the mounting holes on the circulation pump and engine block.
  5. Install hose clamps: Slide the supplied clamps onto both ends of the hose before final seating.
  6. Secure connections: Tighten clamps evenly to manufacturer torque specifications to prevent leaks.
  7. Refill coolant: Use fresh marine-grade antifreeze/coolant mixture per your engine manual.
  8. Bleed air from system: Run the engine briefly with the cap off (following OEM procedure) to purge trapped air.
  9. Inspect for leaks: Check all connections under operating temperature and pressure. Retighten clamps if necessary.

Troubleshooting & FAQ

Q: How do I confirm this hose fits my specific engine model?
A: Verify that your engine is a Mercruiser, GM, or OMC 4.3L, 5.0L, or 5.7L and that your original hose matches the 1-3/4" ID and 12-3/4" tall dimensions. Cross-check the OEM part number 32-87108 against your engine's parts diagram.

Q: Will this hose work if my engine uses a different coolant routing configuration?
A: This hose is engineered for the standard circulation-pump configuration on the listed engines. If your setup has been modified or uses an aftermarket pump, confirm mounting-flange spacing before ordering.

Q: How often should I replace this circulation hose?
A: Inspect hoses annually for cracks, soft spots, or swelling. Replace every 3–5 years or sooner if you notice coolant seepage, reduced flow, or visible deterioration.

Q: What are the signs that this hose is failing?
A: Common indicators include coolant leaks around the flanges, engine overheating, visible cracking or bulging of the rubber, and loss of coolant level without external drips.

Works great on many different size cans
Works great on various size cans. It is a little larger that other openers, but seems very sturdy. It is a little loud and slow, but not a large concern. Very happy with it.

Stopped working after 3 months
It stopped working after 3 months. The motor still runs the gear still turns. But it does not engage the can to cut. I bought it for a post operative situation and I am glad that it worked when for the length of time it did but it's disappointing that I now have to throw this item away.

Meh.
Worked great the first couple of times it was used. But then it stopped cutting into the cans and does not open them. It causes the metal to fray off in small pieces which resulted in getting a piece of metal stuck in my finger for weeks so I don't recommend. It's also very loud.
