In doing my aftercooler maintenance, I'm also going through my fuel/oil cooler. I stripped the paint of and then let it sit in a mix of diluted muriatic acid to clean it. It cleaned up nicely. after closer inspection, I noticed these internal cracks on the seawater inlet side from the seawater...

I'm looking for a good, high-quality tie down to replace the factory cheap ones that came on my boat. Looking for something that will hide the old screw holes or I can do a cut out to accommodate the new ones. Does anybody have any recommendations?

I thought I'd post this in case anyone might need some info on the aftercooler maintenance on a 2008, 48 Sundancer. I pulled my port side aftercooler today for routine maintenance. I bought this boat last March and it had no record of ever having the aftercoolers actually taken off and sent for...

Cummins QSC “low seawater flow” alarm came up today for the Port engine. Cleaned strainer, plenty of flow into strainer, Impellers only have about 80 hours on them, plenty of water coming out exhaust. Ran boat and it doesn’t get above 165 degrees and runs at the same temp as Starboard engine...

I have the dreaded cracked hose problem on my 48 Sundancer. After evaluating the work needed to get to the hoses, I decided it's probably easier to overhaul everything. So, I'm planning to overhaul my entire sanitation system this winter from the toilet bowls back including rebuilding my VG4's...

Anyone know what model bow thruster is on the Sundancer 48 or even better, which anode I need? I'm placing an order from Boatzincs.com for other anodes and though I might as well order this as well in prep for upcoming winter haul out.

I've got a problem with my hydraulic lift and it won't go down. It was working fine and now when I go to put it in the down position, it make a rapid "clicking" sound, I believe at the "down" solenoid. It is a General Hydraulics pump pictured here. I had the problem before and the red knob on...

48 Sundancer ....I'm replacing my exhaust hose this weekend and looking for some suggestions on the best way to cut the new one down to size.. It's a 3" hardwall, corrugated, wire reinforced hose. Thanks,

Well, it seems like I've spent the past two weeks in the furthest parts of my bilge getting on top of deferred maintenance. My exhaust hoses look like they can use replacement. Anyone have experience with the Trident, 252V Silicone Blue Cora-Sil hose? Is it worth the extra money?

As I'm going through my boat one area at a time, I discovered I have the dreaded sanitation hose problem. Has anyone taken on the job of replacing this on their own? I don't intend on doing it but would like to be educated on what this entails. Also, the picture is the hose that runs alongside...

Ok so I want to do an upgrade on my SV20 underwater hull lights. Sea Vision makes an LED retrofit kit for the SV20 Halogen that comes with the 48 Sundancer. Has anyone done this? My problem is, I can't get the old reflector tube out of the brass housing. Has anyone done this? If so, how did you...

Ok, I've been going through my entire boat bringing everything and I mean everything up to new ( when I'm done with this boat ya'll are going to want to buy it because it's going to be like new) . And, I'm pretty knowledgeable on figuring everything out, this one I can't figure out what it is or...

If anyone needs info on a 48 Dancer Heat exchanger inspection/cleaning I just did this today. I was going through replacing all of my anodes and swapping them from Zinc to Magnesium (salt to fresh water move) and came across a problem getting the anodes out. Since this is a new boat to me, I...

This weekend I was able to get out and run the boat. All was fine but then ran into "low fuel". This wasn't a problem as I was headed to get fuel but then all of a sudden I got an alarm stating "low fuel pressure" and I couldn't get to full RPM's. Both engines would achieve about 2K RPM. I had...

I don't have power to my raw water pump for my AC units. Anyone know where the breaker is for this AC power run? Is there a GFI somewhere? I suppose I could try and follow the power wire but it runs into a big bundle that's all tie strapped up. Thanks!

Does anyone know where the coax gets spit out from the TV antenna to the 4-TV's on a 48 Sundancer? Basically, where is the splitter?

My 4th Sea Ray Sundancer....recently new to me. my Sundancer 48! I've learned tons about my Cummins QSC 8.3's thanks to SeaBoard Marine. If you have a diesel boat and don't know about their site, it's a must visit:https://www.sbmar.com/search-sbmar/ It took me about a year to find my boat...
