    Trim Pump Issues

    1995 Merc Bravo 2, 5.7. On one of my drives, I can only get the drive to go up if I remove the "down" hose from the pump itself. Fluid flows freely out of the down line then as the drive goes up. If I leave the down line attached, the pump really seems to bog down, almost like a hydraulic lock...

    Twin I/O Alignment

    I'm wondering about the I/O alignment on my twin screw boat. When the steering wheel is in the straight forward position, both drives look like they are not quite straight. The port one looks as though it is steering to the right just a bit, and the starboard one looks as though it is to the...

    Perma Lube Gimbal Bearing?!?!

    I just opened up two new merc Bravo transom kits [kit # 30-803100T1] to have a look at everything. Much to my surprise... :eek: both gimbal bearings are a "perma lube" bearing, with no hole in the outer race so it can be greased. In addition, the kit came with instructions and a plug to thread...

    Anode Question

    This might seem like a dumb question, and probably is, but here goes anyway.;) In the merc anode kits I bought, there are serrated washers included with the new fasteners. Do these washers go directly under the head of the bolt, or between the anode and the drive itself, to help ensure a good...

    Re-painting Merc Outdrives

    After doing plenty of research, and talking with several companies about their paint products, I decided it was time to refinish my outdrives. The paint was coming off in several areas, and it was time to do them before they suffered any corrosion damage. The first step was to get them media...

    Coupler Runout

    How much runout is acceptable on a Bravo coupler? Today I was double checking the alignment I had done last week after running up the new engines I bought. When I went to stick the bar in, it was tight going in, with grease marks just on top. I got my wife to bump the starter, 90, 180 and 270...

    Engine Alignment / Adjustment

    Need a bit of advice guys. Ok, so I'm installing two new Mercruiser 5.7 357 Magnums, in a twin screw Chaparral. The starboard side engine went well, and had no issues getting it to align properly. The port engine seems to be a different matter. The alignment bar only goes into the coupler...

    Removing Bottom Paint

    When I purchased my Mariah Davanti Z235 last fall, one of the things I wanted to do to it was remove the bottom paint, as it was UUUGGGGLLLYYY! I did a fair bit or research on sanding it off, having it soda blasted, and also looked at using paint stripper. After getting some quotes for sanding...
