When you're planning marine engine propulsion changes, the first fork in the road is whether you're fixing an existing inboard or installing a complete new power plant. These two very different purchases-the DF100 motor mount pair and the Dodge V10 8.0L Indmar marine engine-represent that split perfectly. The mounts cost $119.95 and solve vibration and alignment issues; the engine costs $9,500.00 and delivers a complete, never-fired 305 HP V10.
Quick Verdict
If you have a smaller inboard and the engine is shifting, shaking, or misaligned, the DF100 pair of motor mounts is the smart, low-cost repair. If you're repowering a serious inboard boat and want a rare, complete power plant with zero hours, the Indmar Dodge V10 is the commitment for you.

Where Each Product Wins
- DF100 Motor Mounts win when you need a precise, low-cost repair for a small inboard. They're a pair of mounts designed for 4-point installations up to 850 pounds, with a low-profile design that needs only 1-7/8 inches of clearance.

Product Notes
DF100 Motor Mounts (Pair)

Choose these if your inboard has excessive engine movement or driveline vibration. They're made from heavy-duty cast aluminum alloy and use an oil and fuel resistant elastomer element, so they're built to hold up in a marine engine room. The pair includes 5/8-18 studs, zinc dichromate plated steel parts, and dimensions that fit a 4-inch bolt center. One clear limitation: they're mounts, not an engine. They won't add power, fix internal engine damage, or address overheating. Also, at $119.95, they're a repair part for a specific mounting point, so you need to confirm your setup matches the 4-inch overall height and 2-3/4-inch width before buying.
Dodge V10 8.0L Indmar Marine Engine

This is the big-ticket option for a real repower. It's a complete Indmar marine engine built from the Dodge V10 8.0L truck engine, with an iron block and a design tuned for low-end torque-rated at 305 HP and 450 lb-ft. It has never been fired and shows zero hours, but it does have a few scrapes and scratches from storage. Used as a show piece only, the engine is a rare find for someone undertaking a full installation. Note that it comes without a warranty, so your commitment to this power plant should include a thorough inspection before installation. At $9,500.00, it's a significant investment, best suited to someone who can handle a complete repower and appreciate a rare marine V10.
Final Choice by Use Case
Choose the DF100 motor mounts if you already have a working inboard and only need to solve mount-related vibration or misalignment. Choose the Dodge V10 8.0L Indmar engine if you're repowering an inboard from scratch or replacing a failed engine and want a complete, zero-hour V10 with a big torque curve.
