2 - 350 Mercruiser MAG MPI 300 HP and 350ish hours - Running Take Out's

Dirty Riggers

Jan 13, 2016
Hi guys,

In the next few weeks I'll be removing 2 running 350 MPI engines from a client's boat to re power with diesels.

Normally I don't have the time to deal with used engines but these are nice looking engines that were installed about 4 years ago so I figured I would post them on here.

Photos will be posted once engines are pulled.

These engines have low hours and the hours can be read using a mercury smart craft computer. I don't have one but will see if I can find a merchant guy to pull readings and a print out once they are on the pallets and able to be run.

These will be sold as bobtail engines with all gauges. They are both regular rotation engines.

They will be placed on a crate/pallet and will be able to run them on the hose for interested parties.

Looking to get $4,500 each. Will crate and ship at buyers cost.

If anyone is interested please DM me here or call me at 954-501-3707.

Engines will be located in Stuart, FL 34997
