Ensuring your marine engine's hoses stay securely fastened under the relentless pressure of water, fuel, and vibration is no small feat. That's where the Sierra Engine Parts Oetiker Clamp Kit shines, delivering reliable, precision-engineered clamping power for boat owners who demand performance without compromise. Designed specifically for outboard and inboard engines, this kit replaces worn-out or loose clamps that can lead to leaks, overheating, or worse—engine failure mid-adventure.
Crafted with the marine environment in mind, these clamps resist corrosion from saltwater exposure and withstand extreme temperatures, making them a go-to upgrade for DIY mechanics and professional technicians alike. Whether you're prepping for a fishing trip or a long offshore cruise, swapping in this kit gives you peace of mind and keeps your vessel running smooth.
Pair these clamps with high-quality marine hose replacements for optimal results. Regularly inspect for signs of wear during your annual engine tune-up to catch issues early.
This straightforward process typically takes under 30 minutes per hose, saving you shop labor costs and getting you back on the water faster.
This clamp kit fits a wide array of 4-stroke and 2-stroke outboards from 25HP to 300HP, including popular models in the 40-150HP range. It's a direct alternative for OEM clamps prone to failure in high-vibration setups.

Oetiker-specific pinch-off pliers provide the most control, but heavy-duty diagonal cutters work well for DIY installs. Avoid regular pliers to prevent uneven crimps.
Absolutely, the sizes align with many freshwater inboards too, especially for cooling and exhaust systems where reliable clamping is critical.
To maximize the lifespan of your new clamps, rinse your engine with fresh water after every saltwater outing. During winterization, inspect all hose connections—replace any showing wear proactively. This simple habit prevents small issues from escalating into costly repairs.
