I have a 2000 mercruiser 7.4 mpi. I have had a diagnostics check twice on my engine. The first time was when buying boat.

I have a 2000 sundancer 270 with mercruiser 7.4 mpi with bravo III. I was told the overheat alarm would be a solid sound from a sea ray dealer. I had an alarm go off today while on cruise and it was a loud beep. It would beep, maybe 1 or 2 second pause and beep again. I came off cruise and idle...

My 2000 Mercruiser 7.4 mpi wants to turn over about 5 times before starting. I was told probably the fuel is draining back to tank and the system is not holding pressure. Where is this valve located at? Is it in the fuel tank? Thanks Art

I have a Mermaid air with reverse heat. The air and fan works good on the air side. When turned to the heat side we could hear the unit working and could smell the heat and feel a little heat coming out the vents but the fan would never kick on. What would cause this to happen? We were testing...

Is 27 mph at 3600 rpm's and 38 mph at 4500 rpm about right? Also, when I test drove the boat today it idled at 1300 rpm's and surged a few times. But, after running for awhile it started to idle at 800 rpm's and seem to smooth out. Would it be the computer needed to adjust or could it be the...
