Hopefully somebody can help with some ideas here. I am working on this boat that has 8.1 horizons with 450 hours on them, boat is 8 years old. Engines have run perfectly since new. The last two times out I have had a problem starting the port engine after anchoring for a couple hours...

What do you guys think of this. These fuses are off a a boat with 8.1 horizons. I am pretty sure that they looked like this since the boat was new. I just assumed the burn marks were from somebody using a torch to heat up shrink tubing when they assembled the wiring harness to the starter. Now...

Has anybody discovered that their IAC muffler is suddenly missing? If so, did it get sucked into the engine intake or did it run down the 2 foot long rubber hose that goes from the air intake to the IAC valve? Is this worth investigating?

This boat has 8.1 horizon inboards. For the last year when the engine is running the Port voltage needle at the gauge and smart craft wanders from 12.5 to 15.2. It does not seem to matter what the engine rpm is. I also have noticed that before startup sometimes the voltage on the port only...

ZF 63IV Chirp or "Ding" noise when changing direction of gears (UPDATE 4/19) Hopefully somebody out there with transmission experience has seen this before. 8.1 horizons with 500 hours on them. Put the transmission in gear and all sounds normal. I hear the usual "clank" or "clap" that is...

I have upgraded my SC 5000 System View to the new Vessel View 4 and would like to sell the SC 5000 to somebody here on ClubSeaRay. It is from a 2007 340 Sundancer with 8.1 horizons. I have owned the boat since new and the unit has worked flawlessly. This boat is under cover on a freshwater...

I would like to hear what you guys are using for a general use moisture meter. I am not looking to spend more than $100. Is the "pin" type the best or the "pinless" type? I have seen a couple of "pinless" types at Home depot for about $40 but it sure seems like the "pin" type would be more...

Has anybody replaced the bilge blowers on their 2003-2008 390/40 sundancer or 2003-2009 420/44 sundancer with the Jabsco blowers? My concern is the Amp draw of the Jabsco unit is about 11 amps which is triple what the existing blowers pull. Setting aside the obvious issues with the boat's...

I would like to replace the Shurflo 3.3 GPM fresh water pump that came with my boat with the new Shurflo Aqua King II 5 GPM pump. The old pump is rated at 45 PSI shutoff pressure and I believe 25 PSI restart pressure. The new 5 GPM pump is rated at 55 PSI shutoff and 40 PSI restart pressure. An...

I need help trying to find the trade name or technical name of the tan colored gel coat used on the dash of a 2004-2008 searay sundancer. I understand it was probably provided by a company named Spectrum. Thanks for any help on this. I have a small repair to do on the helm.

I have had this problem over the last few years. After I drain/flush the hot water heater I will have air in the hot water system for about a month. After a while it eventually gets purged out but I bet it takes about 4 to 5 water tank fills for the problem to subside. This is causing my...

I have a Atwood water heater that is 6 years old and it develops heavy white scale buildup inside the tank and also in the hot water lines. I first noticed this a couple years ago when I was getting very low water flow at all the faucets on the boat. The Cold water was fine, it was only the...

What do you guys think about this ZF Hurth 63IV. Since this boat was new the Port transmission fluid has always turned darker much faster than the Starboard transmission. Every year I change the fluid and filter at about 40 to 50 hours. When you wipe the dipstick on a white paper towel the...

(Photo links added)WTS custom bedding for 420/44 sundancer and maybe 390/40 sundancer I have for sale a professionally made V-Berth bed cover and pillow shams that replaced the "Goldenrod" color bed cover that came with the boat (2007 44 sundancer). It is a "slate blue" color, no pattern, and...

Hope somebody can help me out on this. Just got the bottom painted on a boat (pettit hydrocoat) and in the process the fine black sanding dust from the removal of the old bottom paint has stained the gel coat with black spots. It seems that the overnight dew moistened up the dust and turned it...

Does anybody know who the oem is for the water flow sensors/alarms that are installed at the seacock on a current model 50/52 sedan bridge? They warn of a reduction in raw waterflow to the mains. I need to replace both of them and would like to carry spares. I assumed it was sherwood but they...

I just got a look at a 8.2 Mercury Horizon. From the looks of it they have made some good improvements in serviceability. There is a 380 hp and a 430 hp version. This engine will come with a catalyst system that looks real easy to service. I wonder if it will hold up as well as the 8.1...

Can somebody tell me how much my wot rpm will change if I increase the pitch on a 380 da with 8.1 horizons 2.5 reduction gear? Right now I am getting 4680 rpm wot under full load. I would like to go from 22x23 props to 22x24 but am concerned that 1 inch of pitch may be over kill. Maybe 1/2...

Does anybody have experience with having warranty work done on a Sea Ray equipped with Man diesels? I know I may have to fly somebody out to the boat to do the work, but can anybody recommend someone from the Georgia/South Carolina coast?

I have what I would describe as "hard" water spots on my windshield. I can remove them if I use Flitz polish with my rotary buffer but I know there has to be a easier way. Does anybody use a liquid spray-on type remover? Any ideas are appreciated.
