    496 bravo 3 3000 RPM plus overheat

    Thanks for the reply Ted, last night after speaking to my marina manager who said sounds like bravoitis I read through your thread on fixing it and since I used to own a 7.4L bravo I know how tough access is. The way the 04 PC 31 is set up I'm not sure if it's even possible to do with engines...

    496 bravo 3 3000 RPM plus overheat

    Thanks for the response, we decided not to do any troubleshooting this weekend. Our NJ forecast is for beautiful 70s and sunny. Better to have partially usable boat then stuck at the dock.

    496 bravo 3 3000 RPM plus overheat

    Yesterday I help my friends launch their 2004 Formula 31PC with twin 496 mag Bravo 3. They are closed cooling, with about 400+/- hours. Raw pump impeller was new last season he was told by the mechanic who used to work on it for PO the Exhaust was new and never run when they bought the boat in...

    Deep cycle/dual purpose/start battery

    Thanks for the replies. Airshot, I would love to set it up the way you explaine as it totally makes sense and I don't understand why SR didn't build that way. However that would take considerable time and probably expense to separate the circuits and untangle Sea Ray's 30 plus year old wiring...

    Deep cycle/dual purpose/start battery

    As we approach boating season I was thinking of replacing 1 of 3 batteries on our 90 310 Sundancer twin 7.4L inboards. We used her all last season with the 3 unknown batteries that came in her when we bought her in 11/21. She currently has 2 battery banks 1 consisting of 2 group 27 marine...

    1972 Checkmate MX-15 Rebuild

    More great progress. I have been playing and boating is salt water my whole life, don't think I could make the transition to fresh. LOL. Never been to the great lakes though!! BTW I feel you about being lazy when at the boat. Besides not only does it hurt climbing in the bilge of our SR's...

    Thru Hull valve repair or replace

    Since sinking my boat is not what I want to do I will wait until she is out of the water before I start messing with it. I was thinking that I could possibly take it apart and reassemble with it the stuck open position then ad another ball valve. However the last thing I want to do I mess with...

    Thru Hull valve repair or replace

    So one of the other items needing repair on our 90 Sundancer, besides the VacuFlush, see thread below, is the AC system. I was told by the PO it did not seem to blow cold. The first thing I noticed was the hose from the thru hull valve to the strainer look to be in sink your boat condition. I...

    Help with Vacuflush system

    Thanks AD, always a pleasure to hear from you. I will read through the link you sent when I have time. I was planning on replacing the filter just haven't gotten to it yet, it does look long over due and neglected. The head system on our last boat was not functioning but we made do so it has...

    Help with Vacuflush system

    Hi All, We own a 1990 310 Sundancer this is our first season with her and so far we are very happy. One issue we are having though is with the Vacuflush system. I knew from before purchase the seal between the bowl and the mount leaked so the system would not hold any vacuum, I have since...

    1972 Checkmate MX-15 Rebuild

    Hey Zool, figured I would drop in here give kudos on your build. She is going to be real cool when done. I swear I remember seeing that boat on the bay by LBI and commenting on the Chrysler back in the 80s. Hope you are enjoying the big Sea Ray, I know we are enjoying ours.

    Re bedding bow hatches

    I am sure this has been mentioned before but here it goes. After washing the bow/deck of my new to me 1990 310 Sundancer I noticed the head liner around the forward V-Berth hatch was wet. I figured it needed to be re-bedded as a PO put a bead of sealant on the outside but had it down on my...

    Furuno Model 1712 radar

    Yesterday afternoon while the wife was napping I decided to pull the Radar cover, my plan was to make sure the plug did not have any corrosion and to re seat it. What I found was an even easier fix, as soon as I got the cover off I noticed the belt between the motor and the spinning radar thing...

    Nav lights only work battery 2 or both

    Dingbat what you stated is why this is so perplexing. I will try and follow the source in the rat's nest under the dash. "Nav lights normally wired direct to house. Follow nav circuit back to source" Port engine single battery with simple on/off switch. I have not really tried to see what is...

    Nav lights only work battery 2 or both

    Yesterday while showing our new to us 310 Sundancer to a friend, I told him I had replaced the masthead light on the windshield and the stern light on the transom, when I flipped the switch I had no nav lights, I was like wtf they were just working. The boat has 3 batteries, one for the port...

    Furuno Model 1712 radar

    I was at the boat earlier this week when the sun was still with us, it's been gray and rainy here, just for fun I turned on the radar. It seem to have and issue and I get HD-sig-miss error. Manual says to check cable connection, which I will do. Any other suggestions? Not that I plan to use...

    Furuno Model 1712 radar

    I appreciate the feed back, and have decided to leave the Radar where it is because it will be more work to remove and fill in all the holes including the large opening in the dash. I did turn it on and it looked to be functioning although I read through the manual after that so who knows. I...
