496

Ahoy, New to forum, seeking help with an 8.1 in a SeaRay 370. In the process of diagnosing suspected faulty injector number one on port engine (physically swapping injector one with neighboring injector three, to see if fault follows), I encountered a fuel leak at the fuel rail/supply quick...

Hi everyone thanks for answering so many nEWB questions! I am looking for a 28 Sundancer about 15 years old. I have now seen one with twin V6 motors, and one with a single 496. Owner of the 496 is selling the "less maintenance" angle. I am wondering if there is any knowledge out there about...

I've got a sundancer with mercruiser 496's, 2009 model year. Which by the way, I heard was the last year they were made. Something in the lower unit let go this weekend with 550 hrs on one engine. I'm trying to figure out the easiest and best way to get it repaired. Mercury only sells long...

I'm having a problem with overheating and the engines going into "safe mode". It only happens over time when running pretty well full rpms. The temp gauges read 175 when it drops to guardian mode. I live 100 miles from any mercruiser dealer that can work on my boat. I replaced the water...

Good evening, First – I have tried to look at the other postings on Bravo 3 Outdrives for similar items and reviewed what I found. Not finding one that matched – if I missed one, I’ll apologize in advance if this is duplicated. Summary of my normal maintenance – boat is stored inside storage...

I'm new to the forum and considering purchasing a Sundancer 280 for coastal cruising in New England waters. I'd be interested in hearing from other 280 owners as to its seakeeping abilities. How is she on a beam sea, how tender, does she ride dry, etc? I'm an experienced helmsman and know how to...

I have the 496 (closed cooling) with Bravo III's - last week when out the starboard engine hydrolocked. We had idled into a lock and the engine would not start when exiting ... it sounded a lot like a dead battery and as a result of persistent attempts I spun out the starter. Back at the...

I've read dozens of threads on 454 repowering, but it seems like most threads are for larger cruisers with multiple engines or smaller ones where the 383 stroker is a natural choice. I have a 270 Sundancer DA and have received an offer for my engine which is working fine but has 1200 hours on...

I have a heat exchanger that needs to be replaced in my 2003 340 Sundancer (496 engines). I have the part number but here in Ottawa the price from Mercury Canada is $1700! On-line in the US they range around $900 +/- . I haven't purchased any parts from a US on-line site (its a new boat for...

I went to install my Lowrance EP-60R fuel flow sensor on my 496 MAG. Seemed simple enough until I noticed that the fuel lines on the 496 are the -8 size 1/2" inner diameter and the sensor is sized for the 3/8" inner diameter lines (-6 size). Has anyone installed an EP-60R fuel flow sensor on...
