    Furuno Model 1712 radar

    I was mistaken it looks like the Radar was added to the boat around 99 - 00 time frame, at least the manuals say they were printed in 99. Still makes is 20 years old technology. The Garmin GPS was add around 2007ish again that is the date on the manual I have for it.

    Furuno Model 1712 radar

    Hi, My name is Mike and I usually hang out in MerCruiser and restoration forums, I have question about the Radar system on our new to us 1990 Sea Ray SunDancer 310. She was originally equipped with a Furuno Model 1712 Radar. We are bay/fair weather boaters and have no real need for radar, so I...

    Rehab SportCraft 222 1983 deep V hull cuddy walkaround

    Haven't been around much and was catching up. Looking good. I like the use of the Panduit raceway to hide the wires coming out of the ceiling, my rep would be proud.

    MerCruiser 7.4L Bluewater Exhaust

    Over the last couple day since the weather started cooperating I have completed installing the exhaust and refilled the closed cooling systems with coolant. All that is left is to connect the 2 center exhaust tubes and re mount the coolant over flow tanks. Both were in the way of re doing the...

    Thanks for the replies. There is fume detection system and it seems to function. We bought the boat mid November and it was only in the water a couple of days before she was hauled out. I'm still playing and learning all her systems. By season end I will lknow ever inch of her. Anybody want...

    Bilge Blower replacment

    FYI I Found this on Boat US web site. "The best plan is usually to have two blowers, one to blow air out and the other to suck outside air into the engine space. However great care must be taken that the outside air intake is free of CO and other fumes."

    Bilge Blower replacment

    Thanks AD always nice to hear from you. My 250 only had 1 but it was much smaller. So I will put it back the way I found it. Just not sure if the in coming should be extended low or not. I posted on Sea Ray forum also.

    Bilge Blower replacment

    Not sure if this is the right place to ask this question but here it goes. I am in the process of replacing 1 of the 2 blowers in our new to us 1990 Sea Ray 310 sundancer. Both were working but 1 makes a horrible screeching when turned on. Before removal I ran them and noticed that 1 draws...

    MerCruiser 7.4L Bluewater Exhaust

    Yesterday after work I ran to the boat to re-install the raw/sea water pump, while I was doing so I noticed the hose going from the circulating water pump to the heat exchanger was leaking AF. A quick seach on the internet reveals this hose and the following generation 7.4L hose is NLA. There...

    MerCruiser 7.4L Bluewater Exhaust

    SUCCESS!!!!! All bolts are either out or loose, I have not removed outer manifold on port motor yet but since all the bolts have been loosened that is an easy task to remove and replace. These fluted sockets worked great grabbing the stripped bolt heads. Once I had both center manifold off i...

    MerCruiser 7.4L Bluewater Exhaust

    When I took the old Manifold out of my truck I noticed what looks like a date code next to the casting number 1F97. Is is possible these manifolds are 25 years old? They are part of the closed cooling?

    MerCruiser 7.4L Bluewater Exhaust

    Well I had some success yesterday although not exactly what I planned. Although I was unable to remove the bolt I am struggling with I did remove the Port engine center manifold which gives me much more room to work. Note there would have been enough room to slide it off the cut bolt even with...

    MerCruiser 7.4L Bluewater Exhaust

    Thanks Bondo, but it's not the bolt you can see it's the one on the manifold to the head that you can not see. The elbow to manifold joint was leaking right at bolt the arrow is pointing to and ran down and corroded manifold bolt. I do not think the bolt is frozen in the threads as all others...

    MerCruiser 7.4L Bluewater Exhaust

    Was going to try and use my dremel with the cut off wheel, but the are so fragil I was thinking of buying something better to use. Any recommendations? It is ver tight between the engines and I can not see the bolt head at all. I'm going to try and contort myself in there for better vantage...

    MerCruiser 7.4L Bluewater Exhaust

    Thanks Scott, yes that is the plan. I will update after I get to the boat. Stinks not having it in my yard like the 250 Dancer. Question, on the 7.4L in my 250 I used stainless bolt for the manifold with no issues. Came right out after 5 years when I replaced the Manifolds. I thought I...

    Hi all its been a while. Weather is looking up and marina needs me launched mid April. I am so not ready. Today we started removing the crusty old exhaust, started on starboard motor outer side all came apart with no problem. Center side did not go as well but all in all could be worse...

    MerCruiser 7.4L Bluewater Exhaust

    AD I agree, that what all the diagrams I saw show. As mentioned above I expect to find aftermarket junk for a gasket. I was going to head to the boat today to take some notes and photo but its gray and to cold out so I think I just going stay home and keep the fire going.
