Mo's Bottom Line (BLUF)

The Reverso gear pump system permanently mounts in your engine room, allowing you to drain and fill crankcases and transmissions with the flip of a switch. It turns a dreaded chore into a 15-minute job.

Clean, Fast, and Professional

Changing the oil on inboard diesels or large gas engines is traditionally a miserable, filthy job involving hand pumps, spilled oil in the bilge, and a lot of cursing. The Reverso oil change system modernizes the process. It's a heavy-duty, reversible gear pump plumbed directly to your engines' oil pans.

Flip the Switch

The genius of the Reverso is the manifold system. You connect a hose to a waste bucket, turn the manifold valve to the engine you want to drain, and flip the switch to 'Empty'. The powerful gear pump sucks the hot oil out in minutes. To refill, put the hose in a fresh bucket of oil, switch to 'Fill', and pump it right back in. Not a single drop enters the bilge.

Pros and Cons

The Verdict

If you maintain your own inboard engines, a Reverso system pays for itself in time and saved cleanup. It elevates your engine room to professional status.
