I spent all day at the boat, the trim tabs have nothing to do with my problem, only that when they are up the engine rpms go up from 4500 to 4800 which is where I have my problem. Only on port engine, starboardengine water pressure is normal. Engine temperature stays perfect at 154 degrees. I...

Hello, I have a survey on Monday and no way to get to a mechanic or diagnostic reader for a code before then so I hope some of you have some ideas with all your experience. I have a 2007 320 Sundancer with 2 350 mercruiser mag mpi with v drives. My starboard engine will go wide open throttle...

Hi, I have 2 350 mag mpi engines in my 2007 320 sundancer. While climbing into the bilge I hit one of those cheap plastic drain plug and the head flew off leaving the body with the screws and it looks like a hole in the middle still in place. I'm sure this has happened a lot and I'm looking...

hello all, I have a leak in my port side trim tab. The pump is close to it and there is a metal tube that goes through a small hole in the transom. Any suggestions would be appreciated I can't even find good pictures of the entire assembly. Also, my boat is in a slip. thank you so much

hi all, i have a 2007 320 sundancer and the stiching along the top of the rear seat bolster that rests against the transom is unravelling probably due to years of the boat cover fitting snugly against it. I can see two bolts in the back hatch where my power cord is, is that all that's holding...

I have a 2007 320 sundancer with 2 mercruiser 350 mag mpi engines with v drive. I can idle out of my marina and can go 1000, 1500, 2000 and 2500 rpms with no problems. When I get it up on plane at about 3800 rpms it runs beautifully for 2-3 minutes and then the starboard engine shuts off like...

Can an individual purchase computer software or system to show error codes? What is the most economical but effective product to do that? I have 2 mercruiser 350 mag mpi engines, 2007. Thank you

Hi All, I have a 2007 320 sundancer with 2 mercruiser 350 mag mpi engines. Are the fuel filters in what i believe is called the fuel cooling module the only fuel filters on each engine? Are these also what are called water separating fuel filters or is that a different type and place? The...

I have a 2007 320 sundancer with an open raw water cooling system on 2 mercruiser 350 mag mpi engines. I am planning on running barnacle buster through them via the strainer and let them sit for 4 hours per their recommendation and then flush the barnacle buster out. My question is does the...

I have a 07 320 Sundancer with twin 350 mag mpi mercs and a v drive transmission. I was getting an alarm and going into guardian mode which they fixed with a water pressure sensor. This was/is all on the starboard engine. That engine works great cruising at 3800 rpms or so but when I put the...

Hi All. I have a 2007 320 sundancer, I replaced the 4 duckbills which were in bad shape and while I was there also replaced the plunger. Worked well then the vacuum pump wouldn't shut off a few weeks later so I replaced the pressure switch. Now the vac pump runs every 2-3 minutes for maybe 5...

I am having a diver clean my 2007 320 sundancer for the first time. It is has 2 350 mercs with a v drive. From what I have researched I think there is a bar on the transom and one on each of the trip tabs. Are those the only ones on the outside of the boat? I don't see anywhere that there is...

sorry for another question but I have searched high and low on the internet with no luck. 2007 320 sundancer. Got an alarm today, checked temp and oil pressure, voltage, etc and all looked good. Stopped for 30 seconds and the beep subsides and so I tested it out and beep was gone and boat ran...

2007 320 sundancer. Finally got to go out today and relax on our new to us boat. Wasn't sure how long the 4 batteries last approximately with my anchor light, 2 refrigerators, garmin and stereo on? I was running my generator after 15 minutes because I was so afraid of not being able to start...

I am just getting used to the 2007 320 sundancer I just bought. My wife would like to anchor close to shore as we can to enjoy part of the day. The draft on this boat is listed at 33 inches and it is an inboard with the drive shafts and props coming out the bottom of the boat (forgot the...

I have all the duck bill valves and a new plunger, etc. because my vacuum is running all the time. My question is would you replace that stuff while the unit is on the boat or would you take the vacuflush unit out of the boat, replace everything, and then put it back in? Pretty tight either...

I am very diligent about flushing my 320 sundancer with salt off after each use. I have quick connect snap in fittings for my hose so that's pretty quick. My problem has been getting the sea cocks closed and then reopened. They are waaaaay down there and even with the sea cock helper tool I...

I have a 2007 320da, I have read through everything I can find and know that the cockpit refrigerator is ac/dc. Is the galley refrigerator just ac? thx

my 2007 30 sundancer has a small norcold refrigerator outside and is leaking oil. Looks and feels just like motor oil. I'm pretty sure it's coming from the fridge because there isnt anything around it. Any ideas and can it be fixed, these things are $800-$900. By the way, it still seems to...

I just got my "new to me" 2007 320 sundancer. It will be in salt water to I would like to flush it as often as possible with salt off. Do I have to get down in there every time to turn off the sea cock that draws in the salt water every time, they're pretty far down in there (twin merc 350)...
