Hello all. I have a 2005 Sea Ray with the 5.0L MPI engine. Took the boat out this week and the overheating alarm went off after 4-5 minutes of idling. Got a tow back and loaded back on trailer. Popped the thermostat out and it appeared to be stuck. I cleaned it up real good and took it home and...
Hello all,
I have a 2005 Sea Ray with a Mercruiser 5.0L MPI engine. Cold starts off the trailer perfectly every time. I shut the engine off after running for a little while, getting the engine up to operating temperature. I sit for a half hour up to 1.5 hours and try to crank up but it will not...
Hello all. I need more orange alternator wire for my 70A alternator. Does anyone know a part # or the size/type of orange wire Mercruiser uses? The wire has nothing written on it.
I have a Mercruiser 5.0L MPI Bravo 3. This past Saturday, I killed my batteries while playing music all day. I got a jump and got the boat started. I noticed when I took off that the boat seemed to lack the normal power. About half way back to my destination, I noticed that the battery gauge was...
What is the normal water pressure for the Mercruiser 5.0L MPI Bravo 3. After impeller change, mine is idling at 10-15 psi and getting up to 40 psi when cruising at 30 mph. This seems too high. The engine temp will rise to 170 and sit there until I slow down, then it begins to cool. Any ideas?

So my wife decided to crank the boat up while beach on sand for over 20 minutes, thus shredding the impeller. I did not realize it until we took off and the gauges were reading only 1.4 or so psi at 35 mph. It did overheat at idle but there was enough water...
Is Meguairs Ultimate Compound ok to use on mildly oxidized black gelcoat? My local stores do not carry any 3M product so this is my alternative if suitable. After applying this, I would use the 3M Perfect It Polish Swirl removed followed by wax.
Hello all. I have a 2005 sea ray with the Mercruiser 5.0L MPI engine. Last night when getting off the lake, I put the boat in neutral while coasting up to the dock. I then put it in drive and the engine just shut off. It cranked back up everytime but shut off everytime I tried putting it in gear...
Hello everyone. As my title suggests, I have a 2005 Sea Ray with 5.0L MPI Bravo 3. For the past year, I have had a problem with the engine not heating up. In the middle of the Summer, the engine temp would rise to maybe 115 degrees. I verified the operation of the thermostat and even replaced it...
I have a 2005 Searay with 5.0L Bravo 3 MPI. When starting cold and placing the throttle in forward or reverse, the engine will hesistate slightly. It has done this the past 4 times I've taken the boat out. Any ideas?
Also, can you rev this engine while in neutral? If so, how do you do this. Thanks.
This past Saturday I discovered a small hole about the size of a BB just above the pointed part of lower unit and Skag (Opposite side from Propeller, Sorry but I am not quite familiar with all the terminology yet). So my first instinct was the fill this hole with Marine silicone gel because I...
I changed my lower unit lube oil yesterday in my 5.0L Mercruiser Bravo 3. The old oil I drained from lower unit did not appear milkly and there were no signs of water that I noticed. While rushing to re-install drain plug after pumping new lube oil (I used Super Tech Marine Gear Lube), I did...
I have Mercruiser Bravo 3 5.0L MPI. Is there an easy way to change these spark plugs? I cannot even get my hand to the #1 spark plug because it is so tight. Is there a trick to this?
