When you're shopping for an inboard boat engine, the first question is usually whether you want a brand-new, zero-hour powerhouse or a practical replacement that's ready to drop in. The Dodge V10 8.0L Indmar Marine Inboard Engine and the MerCruiser Marine 5.7 L 350 V8 REMAN sit at opposite ends of that spectrum, and the price difference makes the decision even more interesting. Understanding the difference between a zero-hour new engine and a used remanufactured unit is essential before you commit.
Quick verdict
If you want a never-fired V10 with zero hours and serious low-end torque, the Dodge V10 8.0L Indmar is the showpiece choice. If you'd rather save about $4,500 and get a freshwater V8 that's described as running great and being drop-in ready, the MerCruiser 5.7 L 350 V8 REMAN is the practical swap.

Where each product wins
The Dodge V10 8.0L Indmar wins if you want the zero-hour engine, a high-displacement V10 with 450 lb-ft of torque, and a new-condition status for a special build. It's also the only one of the two listed as new. The 8.0L displacement and 450 lb-ft of torque give it a distinct low-end character.
The MerCruiser 5.7 L 350 V8 REMAN wins if you need a straightforward freshwater V8 for a MerCruiser inboard setup, want to keep the project at a lower price, and already have a transmission or can reuse the one from your boat. It also includes the bell housing. If you already have a transmission from a 5.7L MerCruiser setup, this engine keeps the project simpler.
Product notes
Dodge V10 8.0L Indmar Marine Inboard Boat Engine Motor Brand New 0 Hours
This is a rare find: an Indmar marine engine based on the Dodge V10 8.0L truck engine, with zero hours and never fired. It's an iron-block V10 that produces 305 HP and 450 lb-ft of torque, and the oil is still in the crankcase from storage. The trade-offs are worth noting: there's no warranty included, and the engine has a few scrapes and scratches from years in storage. If you're building a project around a true V10 with serious low-end torque, this engine gives you a new-condition starting point.
MerCruiser Marine 5.7 L 350 V8 REMAN Inboard Engine FRESH WATER Drop In Ready CW
The MerCruiser 5.7 L 350 V8 REMAN is designed for a more direct swap. It's a freshwater V8 described as running great and being drop-in ready, with clockwise/right-hand rotation and the bell housing still in place. The main limitation is that the transmission has been removed and is not included in the sale, so you'll need to supply your own or reuse your current one. If you're replacing an existing 5.7L MerCruiser inboard, this is the lower-price, more practical route.
Final choice by use case
Choose the Dodge V10 8.0L Indmar if you want a new, zero-hour V10 with 305 HP and 450 lb-ft of torque for a special build and you're comfortable spending $9,500 without a warranty.
Choose the MerCruiser 5.7 L 350 V8 REMAN if you're doing a freshwater V8 replacement, already have a transmission, and want to keep your budget closer to $5,000.
