Hi. My Mercruiser 496 will run when first started up. But after warming it will not go past idle without braking up. Any thoughts? Thanks for any info . Mike.

have you done a complete tune up? also check all your grounds and electrical connections.

Thanks for the reply. I took boat to a marine tech. I had a bad riser temp sensor and a bad block pressure sensor. They put the engine into safe mode. Waiting to get it back tomorrow to test it out on the water!
