Mercruiser 496 HO with 230hrs runs perfect. Raylar roller rocker arms. Everything else is stock. I purchased it in April for 17k. It has the wrong power curve for my application. Send your mechanic to do any tests you would like. It can be started in the crate for testing purposes. Sold as is. No shipping local pickup only. If you wish to arrange pickup I am ok with that. Please email any questions you may have. I can send video of it running. Comes in Mercury shipping crate.
