V10-350
The Mercury Verado V10-350 is a naturally aspirated 5.7-litre 64-degree V10 petrol outboard rated 350 hp. The current catalog engine is the July 2025 enhanced calibration of the 2022 original.
The current V10-350 is the July 2025 performance-enhanced calibration of Mercury's 5.7-litre V10 Verado, not a new displacement. Mercury's October 2025 sell sheet publishes the same hardware figures as the 400: 5.7 L (349 CID), 64-degree V10, 40-valve quad-cam DOHC, WOT 5800–6400 rpm, dry weight 695 lb / 316 kg on 6.4-inch gearcase models (685 lb / 311 kg on the 5.44-inch gearcase). The 2025 change is a mid-range torque tune; Mercury states 15 percent quicker 0–50 mph than its own original V10 350.
The original V10 350 was announced 15 November 2022 with the 400 as the first production V10 outboards. Do not average the two calibrations. Published displacement, weight and WOT are the same; only the mid-range map changed.
Two gearcases remain on the 350 only: 6.4 inch at 2.08:1 and 5.44 inch at 1.75:1. This is not the older supercharged L6 Verado 350.
