Camoo Tilt Trim Seal Kit for Yamaha 115–250HP Fast Strike & Showa-style units — Viton seals, 3-cylinder rebuild with extra O-rings

Camoo Tilt Trim Seal Kit rebuilds the seal assemblies on 1997 and newer Fast Strike/Showa-style Yamaha trim tilt units, using durable Viton components to resist saltwater and extend service life.

This comprehensive seal kit is engineered to replace worn or leaking seals in Yamaha 115–250HP trim/tilt power units (Fast Strike and Showa-style three-ram integrated systems), plus many compatible Suzuki, Honda, Tohatsu and Nissan applications. The kit contains seals for all three cylinders and extra O-rings needed during a standard rebuild, helping restore smooth, leak-free operation without replacing the entire unit. It’s intended for 1997 and later models and fits an extensive list of part numbers used across Yamaha and other brands; it does not fit Yamaha 200–300hp four-stroke lower units.

Which engines and trim units does this kit fit?

This kit covers a wide range of Fast Strike and Showa-style integrated trim tilt systems on outboards from about 115HP through 250HP (20" shaft for some 225/250 models). Fitment is based on the trim housing style and part numbers rather than just horsepower, so confirm your part reference before ordering.

• Compatible with Yamaha models using 60X/63P/64E/67H/68F/68V series part numbers listed in the product features.
• Supports 115HP, 150HP, 175HP, 200HP and some 225/250HP 20" shaft units.
• Also fits many Showa-style 3-ram integrated systems from Suzuki, Honda, Tohatsu and Nissan.
• Not compatible with Yamaha 200–300HP four-stroke lower units.

How will Viton seals improve durability in marine conditions?

Viton elastomer is chosen here for its resistance to saltwater, fuels, oils and heat — properties that make it well-suited to outboard trim systems exposed to harsh environments. Upgrading to Viton components reduces swelling, cracking and rapid degradation compared with generic rubbers, which helps the rebuilt trim unit maintain performance longer.

• Viton resists chemical attack from fuel and oil splashes common in engine compartments.
• Improved resistance to UV, heat and saltwater extends seal life in marine exposure.
• Reduces frequency of rebuilds when installed correctly and with clean mating surfaces.

What parts are included and what tools or steps should I expect?

The package includes seals for all three cylinders, additional O-rings and other small components shown in the product images. Typical rebuilds will require disassembly of the trim unit, careful cleaning of bores and mating surfaces, and installation of seals with proper lubrication and alignment to prevent damage during assembly.

• Complete seal set for three cylinders plus extra O-rings as pictured in the listing.
• Recommended tools: basic hand tools, seal driver or soft mallet, clean solvent, grease appropriate for Viton seals.
• Follow a service manual or professional guide for torque specs, bleeding procedures and safety steps.

Will this kit fix a leaking or sluggish trim unit?

Replacing worn seals often cures common leaks and many performance issues caused by internal fluid loss or contamination. However, seal replacement won’t repair damaged pistons, scored bores or mechanical failures; inspect internal components and housings and measure tolerances to ensure a successful rebuild.

• Ideal for restoring hydraulic integrity when internal components are in good condition.
• Check for scored rams, pitted bores or bent components that require additional repair.
• Consider professional inspection if unsure about internal damage before reassembly.

Who is this for: Technically minded boat owners, marine mechanics and service shops who maintain Yamaha Fast Strike and Showa-style three-ram trim/tilt systems will benefit from this Camoo kit. It’s suited for anyone who wants a long-lasting, saltwater-resistant seal replacement for 1997 and newer 115–250HP outboards (verify specific part numbers and shaft lengths). If you prefer professional installation, provide your mechanic the kit and the engine’s trim part number to confirm fitment before starting the rebuild.
