Mangrove Products Boat Transom Saver TS-Pipe Glow-In-The-Dark, 1-Pipe — Reinforced Transom Support for Single Outboard Ram

Mangrove Products Boat Transom Saver TS-Pipe (3-RAM) Glow is a reinforced transom protector designed to support and stabilize a single outboard ram while reducing stress on the boat transom.

This TS-Pipe is engineered for owners of compatible Yamaha, Mercury, Suzuki, Honda, Tohatsu and Evinrude outboards who need a durable, easy-to-install transom support. Built to align with specific engine models and ram placements, the Glow finish increases visibility and resists corrosion. Read on to confirm fitment, learn the simple checks and modifications some installations require, and see how this product protects your vessel while maintaining trim range.

Which engines and configurations will this 1-pipe TS-Pipe fit?

This TS-Pipe supports a defined set of models and horsepower ranges. Fitment varies by manufacturer, engine generation and whether your installation uses one or two rams. Carefully cross-check your engine model and year against the fitment guide before purchasing.

• Yamaha: selected F-series four- and two-stroke models (F115 older models, F150–F350 and XTO 425–450 where noted; some models require modification).
• Mercury & Suzuki: supported 175–350hp ranges for two-pipe engines and specific one-pipe starboard applications; Verado and some ProXS/Racing models excluded.
• Others: Honda (BF 75–350hp), Tohatsu (MFS/BFT 75–250hp), Evinrude E-TEC early-gen fits in specified ranges; some E-TEC units need a bored entry hole.

How do I verify trim and avoid fitment problems?

Trim limiters and piston clearance determine whether the TS-Pipe will install without interference. Perform a quick maintenance-latch and piston-length check to confirm compatibility, and trim or trim-limiter adjustments may be necessary prior to mounting.

• Check maintenance latch: if it won’t engage, a trim limiter may be active.
• Measure piston tip to bracket contact at full tilt up—must be 9.25 inches to clear the TS-Pipe.
• If measurement is under 9.25 inches, trim excess rubber from the TS-Pipe tip per instructions for clearance.

Are modifications required and what do they involve?

Some engines need minor rubber trimming to clear hydraulic reservoirs or trim components. These are simple, precise cuts—approximately 1/8 inch in targeted areas—to allow the TS-Pipe to slide past obstructions without altering structural support.

• Yamaha F150–F200 (certain years) and VMAX/HPDI/SHO: cut 1/8" from the rubber base on left/port ram installations.
• Honda 225hp left/port ram: trim 1/8" from rubber base for hydraulic clearance if using TS-Pipe on that side.
• Some Evinrude E-TEC units: bore the entry hole to clear the trim piston tip/head where noted.

What installation tips and maintenance should I follow?

Simple prep and periodic inspection keep the TS-Pipe functioning and protect the transom. Use the fitment guide before ordering, ensure clearance measurements, and re-check seals and rubber for wear during routine maintenance.

• Confirm engine model/year against the provided fitment list before purchase.
• Perform trim and piston clearance checks at full tilt up to avoid binding.
• Inspect rubber seals and fasteners seasonally and re-trim if additional clearance is needed.

Who is this for: The Mangrove Products TS-Pipe (3-RAM) Glow — 1-Pipe is aimed at boat owners and marine technicians with compatible mid-to-high horsepower outboards seeking to reduce transom stress and maintain stable ram placement. It’s ideal for recreational anglers, tournament skippers, and marine service pros who match their engine model to the fitment guide and are comfortable performing small, specified modifications when required.
