I have a 1998 Sea Ray 400 DA and the fridge has quit working....maybe. I have had the boat for 8 years and never had one issue with it. In the last 2 weeks it has been sea trialed, mechanically inspected and surveyed. Now the fridge does not work. The light comes on in front with battery or...

Over the last few years I have a little water in the forward bilge. Everyone told me this is normal. In this time frame I have had a few water leaks as well (water heater, fresh water pump, coolant hose, etc.) so I never put a lot of thought into it. I also never noticed the forward bilge...

I have 1998 SR 400 Sundancer and the windlass is struggling to pull the anchor up due to slipping. I’ve replaced the spring in the tensioner but it’s slowly getting worse. It is a Progress 1, but there are about 4 different sizes. Where can I find the size stamped on my windlass

So, I’ve lost a hose on the seawater pump before and I know the engine temp rises quickly. So my question is, if you lose coolant out of the internal cooling system will the engine temp rise quickly as well. I lost coolant in the bulge and found a leaking cap On the internal cooling system...

1998 sea ray 400 with 7.4’s. About 3 weeks ago the starboard engine wouldn’t start. After calling a mechanic he suggested changing the ignition module. I couldn’t find a marine module so I got one at the local automotive store per his suggestion. Once installed it fired right up. I ordered a...

So As I head back the 10 miles or so on the port engine, should starboard be in neutral or forward?

The marina mechanic, who is no longer there, told me something about repairing the shaft seal and after looking at it I’m a bit confused. Port side shaft seal is leaking. I placed an endoscope to view. At idle there is a slight drip. At operating speed a bit of a spray. I was told that...

No issues until this weekend. The port engine oil pressure is significantly higher than normal. It’s around 60# at idle and 80# running 3600 rpm. What would cause this? Understand gauge could be incorrect but has been spot on with strbd.

1998 400 with 7.4s. I noticed some water in the bilge so I took a borescope and fixed it on the port side shaft packing gland. Sure enough it leaks at higher rpms. Since I don’t know much about this I need some education. My understanding is sometimes there are extra packing rings installed...

1998 Searay 400 with 7.4’s. When coming off plane the port engine will roll the RPM’s down to about 600 as it should, but the. It will rev a little on its own and fluctuate between 1000-1100 rpm’s. Not every time, but I would say the majority of the time. If I use the throttle to rev it a...

I’m replacing the oil line that attaches to the oil filter housing on 1998 400 with 7.4’s. It doesn’t look like there is any thread compound or anything on the one I am removing. Any recommendations on thread compound for the brass fitting that screws into the filter housing or should I leave...

1998 400 Sundance. Came down a month ago to check on the boat and the batteries were dead. Turned on the AC converter and it popped up to ~5 amp draw which was pretty normal. Batteries charged overnight and all was good. Came down to dewinterize this weekend and batteries were dead again...

What is the best way to clean the spark arrestor? Soak it in gas/solvent? Also, I assume it comes off without removing the manifold on 7.4's? Sure looks like a tight fit to get those bolts out.

I have a 1998 400 Sea Ray w/EFI. I fired up last night to go to dinner and the starboard engine did not immediately fire off as it normally does. I tried it again and it cranked for a few seconds and started. We proceeded to dinner without any further incident. However, when we went down to...

After using the shower in the forward head of my 1998 400 Sundancer for the first time this year, I noticed the valve in the shower would not close all the way allowing water to drip out of the shower head. I assume the valve in on/off knob for the water has deteriorated due to age and needs...

Has anyone ever repaired the check valve/non-return valve on their fresh water pump?

I've been considering installing a spare battery and charger. I wanted to install a battery that was only for my sound system and a single bank charger for that battery. I purchased a ProMariner 6 single bank charger to fit the bill. I was surprised when I received it that it had a cord with...

Recently I noticed the voltage readings on the meters of my 400 SD occasionally jump up to a little over 15 volts for a few seconds while underway. I have digital volt meter that is separate and it confirms the same voltage. Typically the voltage runs about 13.2v-13.5v. The last 2-3 weeks I...

Generatot starts right up and runs fine, but no voltage output. The only thing I did since the last use a couple of weeks ago was change the starting battery. Starts right up but new electricity. Any quick suggestions?

My boat (400 SD) always seems run right at 160* F on both engines. I changed both gauges last year. All this year they have been at 160* F, until this past Friday night and they both were running 165* F. So, Saturday morning I pulled the strainers out and they had a fine film of algae on...
