The oil lines on my Mercruiser 7.4 Gen V are leaking at the point where the hose is connected to the fitting. It's just a slight drip, but it's enough to make a mess. I'm looking to replace them, but have found out that they are no longer available. I'm assuming this is because people have...

Hi John, I know it's been about 10 years since you originally posted your elecetric fuel pump conversion information. I've got a '94 SeaRay Sundancer 270 with a single 7.4L Merc Gen V, and would like to do the same. For whatever reason I don't see the photos you posted way back in '07. Any...

I have a Bravo III that's stuck in forward gear. Attempts to use throttle only from the control arm at the helm didn't work. The boat still lunges forward. I disconnected both lower and upper shift cables. Upper moves, but the lower is stuck. I removed the drive, and the lower cable moves...

Anyone, I have a Gen IV (I think) 7.4 L Mercruiser that keeps detonating cylinders (#1, then #5). I've gone through 2 motors so far, and hesitant to replace the motor again until I figure out what's causing the pre-ignition. I'm thinking it's a fuel issue, but can't seem to isolate the...

These guys raked me over the coals. Last year I purchased a remanufactured 7.4L 454 Mercruiser from them. When it arrived the motor was severely damaged in shipment because they don't know how to secure an engine to a pallet. They used (2) plastic straps to hold the engine down. Well the...

Winston, I hope you didn't buy a motor from US Engine. After a year of battling with them ove a warranty, I finally caved in. They suckered my for the whole $3K. Wouldn't even give me the core value for the motor. So this is me doing my best to sabotage their name. Spread the word for me...

Just wanted to let anyone else know what the problem was with my bilge pumps. It came down to two severed wires. one of the leads on each of the float switches had either been severed, or the insulation had softened from the oily bilge water and the internal wired decayed. I replaced both...

I thought 30 amp fuses were big for bilge pumps too, but I checked them anyway. I can't imagine there being a seperate line going directly to the battery if all of the pumps are wired through the "bilge breaker box". The breakers should take care of any shorts in the line. I looked for loose...

Thanks Travis. I too have the "Sure Ball" float switches. I removed them both and manually moved the switch which did nothing. That's when I cut the leads and tested for power. Which showed no power getting to the switch. So, what I've found is the float switches are fine, the pumps are...

Thanks for all the quick replies. Both the primary and emergency pumps are functioning properly. When the bilge has water in it (manually added) I can flip the rocker switch on the dash, and pumps do there job. However, before flipping the manual switch, the flaot switches should of engaged the...

I have a 1994 Sea Ray Sundancer 270. I noticed over the weekend that both my primary and emergency bilge pumps did not work when the float switched were engaged. All the breakers on the "bilge breaker box" were not tripped. One thing I noticed was the rocker switch on the dash was only an on/off...
