    Mercruiser 5.7 EFI Fuel pump noise normal? With video.

    I bought a 1997 Maxum 2100 SR2 about a month ago. The boat is very nice but has an issue when cruising above 3500 RPM. The boat starts to backfire through the TBI unit. I pulled the distributor cap and found lots of corrosion, I could tell it was original, so I replace the cap, button, ignition...

    Trim leaking down

    I noticed this happing some last year before I stored the boat. With the trim all the way up, over a few days it will slowly start to come down. I pulled the boat out of storage and the lower unit was on the ground. I have no visual leaks and the reservoir is full. Where should I start looking?

    2 barrel Rochester rebuild question

    I am wondering which needle to use in the rebuild kit, the solid or spring needle. The instructions to the kit I bought say the spring needle is recommended over the solid.

    New U-joints feel like they are binding

    I just replaced both yokes and both U-joints. The short yoke on the drive had a groove in it causing an oil leak. I bought both yokes from this site, made by Mallory. They both look to be beefier than the OEM. I bought the U-joints from Advance Auto, they are made by Brute Force. Another member...

    Power Steering shudder when turning left

    The last time I had the boat out it seemed like I had no power steering at all. So I figured the pump was bad. I put on a new pump. Yesterday after work I pulled the boat out of the garage and fired it up in the driveway. I made sure to prime the pump before I started it. Anyway, when turning...

    First time out with fuel injection, 305 MPFI

    Well actually my second. I took it out yesterday and it ran horribly, the timing was way off. I was running on a factory GM TBI timing map. It started to rain so I had to load it up. I did some research last night and found the factory timing curve for a 350 Mag. I manually entered that timing...

    Bellows question

    Where do the 2 flat spots on the gimbal bellow go? I am guessing they are there for clearance around the hinge pin area since there is one on each side?

    Hinge pin stuck

    Well I bought a hinge pin tool and within 30 min it was trash. I managed to get one pin out but the other one is stuck. All the points on the tool rounded off. I was able to get the exhaust and u joint bellows out, so I can see the back of the pin. Are you guys just heating these things up...

    Merc Drive identification 1991 Alpha 1

    I have a 1991 Glastron with a 5.0 Merc Alpha 1. The water pump is bad in the lower unit and I want to make sure I get the right one. I noticed when looking for pump kits that I might be right at a year/model change. I am also thinking about going ahead and changing out the gimbal bearing and...
