Hi all, i have a Merc 5.7 EFI. Recently i have noticed a high pitched noise coming from the engine while it's running. Seems to be more pronounced when the engine is warm vs when it's cold. It doesn't seem to change with change in RPM, it's just a constant high pitched humming sound. I have...

Hi all. Engine is a merc 5.7 efi with closed cooling. I've noticed a bit of the green antifreeze dripping into the bilge lately so i started to look around closer. On the port side i noticed a few drips on the boot of the spark plug. Using my camera i can see a small puddle of the AF on the...

Hi everyone, i'm looking for any tips on how to check the fuel pressure on my 5.7 EFI. It's something i have never done before but would like to start doing as part of a maintenance routine, if possible. Also, i have reason to believe the fuel pressure may be too high as there is an obvious...

Hi all, I am at the boat replacing all my ignition wires. I got to the coil, pulled off the wire and this came out (see photo). Uh oh, that can't be good. Can anyone with knowledge help me out, I'm assuming I need a new coil? Thanks, Jeff

Hi all. Engine is a merc 5.7 efi in a 2002 sundancer. I was at the boat today doing a few things and decided to start the engine and let it warm up since i havn't used it in over a month. Turning the key once gets the standard 2 beeps and the priming of the fuel pump. Then when i turn the key to...

Hi all, been noticing this sheen in the water lately while running the engine (photo attached). I had the mechanics scope the engine and they said everything looks fine (fuel pressure, computer tested, not running rich, etc). While I trust their word, this doesn't seem normal. I wondered if...

Hi all, Before having the mechanic diagnose my engine, i'm curious if anyone on here has some ideas for me. Merc 5.7 EFI in a 2002 sundancer 260. Lately the engine is putting off a lot of exhaust/smoke at startup and beyond. It's not a black smoke, just excessive exhaust. It smells like exhaust...

Hi all. Looks like I need new props for my bravo 3. The shop is pricing the OEMs for $850 a piece. Does that seem about right? Are there cheaper alternatives without giving up performance and longevity? I have the bravo 3 on a 5.7L efi. Max WOT as labeled on the engine is 4400-4800 rpm. Any...

Hi all, Curious if there are any ways to tell when manifolds needs replacing? I know that if they are clogged enough, water won't pass through and the engine will over heat, or even worse if there are leaks. But, are there signs to look for before it becomes catastrophic? Will the engine temp...

Hi all, hope everyone is enjoying the summer heat. Hoping someone can shed some light on an issue i ran into the other day. Fired up the boat before heading out and it started up fine (when cold it cranks for a few seconds before it fires up, and that is normal to me since i've had it). I...

Howdy all. My 02' Sundancer 260 is starting to get some rust spots on the swim deck. I figured the swim deck was made of fiberglass, so i'm not sure how there are rust spots. Has anyone seen this and know how to best get rid of them/prevent them from spreading? Thanks

Hi all, last summer my remote oil filter lines were showing signs of wear and were leaking oil into the bilge. It was a slow leak, but over time the bilge got pretty full of oil. A few months back i replaced the those lines with new ones and it appears the leak is no longer happening. Because i...

Hello, My boat has a Standard Horizon GX2200 series VHF radio in it. Being new to the boat as of this past summer. i havn't spent much time messing around with the radio, but with some travel plans set for this spring/summer, i want to ensure it is working properly. It seems i can receive...

What do people out there use for bedding in their v-berth bed? The few times we have stayed on board, we have just thrown blankets down over the stock cushions and it's been alright, manageable for a few nights. But i'm curious if anyone uses sheets, or has custom made sheets or uses mattress...

Ive been looking for what engine oil I need to use for my engine. I have the Merc cruiser 5.7 EFI in my 2002 DA. The previous owner has some bottles of Quicksilver 25w-40 that he gave me, and I've used it to add a little here and there with the oil leak I've had. Now that it's repaired I want to...

Hi all, looks like my pro marine battery charger is not charging the batteries on my 02' 260 DA. It is a Pro Marine Flyback 20-3 (assuming it is the original but not sure, photo attached). I'm plan to take a trickle charger down to the boat later to charge the starter battery enough to fire it...

Hi all, I've been noticing the bilge in my boat getting thicker and thicker with oil lately. Figuring I had a leak, so I checked my oil level and it was indeed low. I looked around and found the hoses that connect to the oil filter have oil at the transition from pipe to hose. I cleaned all that...

Hello all, I've seen this topic thrown around a bit but have never heard any definitive answer. I typically cruise my 2002 260 DA around 3500-3700 RPM. In calm conditions and little to no current, the built in speedo reads about 28-30mph while the GPS unit reads 20-24mph. To me the speed of ~28...

2002 DA260. After a little rain recently i found some traces of water that trickled in around the windshield. What I found appears to be some bad rubber trim between the frame and glass in a couple areas of the windshield. In a couple spots specifically, on the lower trim pieces, i can push on...

Does anyone know where the fuel tank sending unit location is on a 2002 260DA? Having some issues with the fuel guage sticking around 3/4 tank. When i turn the engine off, the needle goes to empty, when i fill up the tank, the needle moves to full. However, once the needle gets down to 3/4 tank...
