When you're deciding between repairs and new propulsion in marine engines propulsion, the first question is whether you need a replacement part or a complete power source. The two options here force that choice plainly: structural motor mounts for an existing inboard motor versus a compact outboard motor that can run a small boat on its own.
Quick verdict
If your inboard engine is already in place but its mounts are tired, the DF100 mounts are the focused structural fix. If you need a self-contained motor for a small boat, the outboard is the one that produces thrust. The listed prices are $119.95 for the mounts and $265.35 for the outboard, so the decision depends on what role each piece plays.
Price and purpose at a glance
| Item | Listed price | What you're buying | Best fit |
|---|---|---|---|
| INBOARD ENGINE MOTOR MOUNTS DF100 PAIR MARINE BOAT MOTOR MOUNT ALUMINUM BASE | $119.95 | Pair of aluminum-base motor mounts with zinc-dichromate-plated steel parts and elastomer elements | Inboard engines needing 4-point support |
| 5.5 HP 4 Stroke Outboard Motor, Outboard Motor, CDI Boat Engine Air Cooling | $265.35 | Complete air-cooled 4-stroke outboard with handle operation and 0.18-gallon tank | Small boats up to 8.2 feet |
Where the DF100 motor mounts win
The DF100 mounts are the right call when your boat already has an inboard engine and the current mounting points are worn. All steel parts are zinc dichromate plated for corrosion resistance, and the low-profile design needs only about 1-7/8 inches of clearance. The manufacturer recommends these mounts for up to 850 pounds, so they're a structural replacement rather than a new power system.
Where the complete outboard wins
The outboard takes over when you need a complete, ready-to-run motor. It is built for small boats and includes CDI ignition, 52CC displacement, and 1.82kW output. A 3-year warranty adds a defined safety net. If you don't already have an inboard engine to repair, this is a self-contained route to getting your boat moving.
Product notes
INBOARD ENGINE MOTOR MOUNTS DF100 PAIR MARINE BOAT MOTOR MOUNT ALUMINUM BASE
The Bushings Inc DF100 mounts are replacement motor mounts, not a motor. The aluminum base is heavy-duty cast alloy, and the elastomer element is formulated to hold up to oil and fuel exposure. Steel parts get zinc dichromate plating to resist corrosion. The dimensions are specific: 4-inch overall height, 1-7/8-inch base-to-rim height, 4-inch center-on-bolts spacing, 5-inch length, 2-3/4-inch width, and a 5/8-18 stud. That low profile requires just 1-7/8 inches of clearance above the casting base. Choose these if your inboard engine's existing mounts are degraded and the 4-point layout matches. The limitation is that they do nothing by themselves: you need a compatible inboard engine and a boat structure designed to accept 4-point mountings. They are not a stand-alone propulsion solution.
5.5 HP 4 Stroke Outboard Motor, Outboard Motor, CDI Boat Engine Air Cooling
If your boat is small and lacks a built-in engine, this 5.5 HP outboard is a complete power unit. The 4-stroke, air-cooled design includes a CDI ignition, a 52CC displacement, 1.82kW output, and an 8,500 rpm rotation speed. A 0.18-gallon fuel tank powers it for 40 to 70 minutes per fill, and the handle operation gives you direct control without a separate throttle console. It is intended for boats up to 8.2 feet in length, so it suits fishing trips or recreational cruising. The 3-year warranty is a useful backstop for a new engine purchase. The main constraint is runtime: with that small tank, you'll plan trips around the 40-70 minute window or carry extra fuel. It is not a high-capacity cruiser motor; it is a compact outboard for short, practical outings.
Final choice by use case
Choose the DF100 mounts when your inboard engine already exists but its mounts need replacing. Choose the outboard when you need a complete motor that can power a small boat on its own. If the goal is to fix what's already mounted, the DF100 mounts are the targeted answer. If the goal is to add propulsion, the outboard is the one that moves you.
