    5.0 MPI Outdrive Gear Ratio

    I have an 86 Sea Ray Sundancer 250 project boat. I have a donor boat with a 5.0 Mercruiser MPI (260 HP) with a Gen II Outdrive with a 1:62 gear ratio. My initial thought was this was incorrect as I was under the impression that V-8's had the 1:47 ratio. I did a little research and saw that in...

    82 Mercury 50hp cowl latch needed

    The cowl latch hinge on my 82 Mercury 50hp broke. It is part number 52739 and is obsolete. This is the latch that holds secure the top cowling. Does anyone have any idea where I can get one? I'm going to try calling around to local places this week but figured I would post here as well.

    82 Mercury 50hp No Spark from 2 of 4 cylinders

    I have an 82 50hp Mercury (s/n:06224664) that when I fired up for the first time this season sounded rough. I have confirmed that the bottom 2 cylinders (3 + 4) are getting no spark. I have verified that the plugs, wires, and coils are not the problem. I also verified that it was not a grounding...

    Adjusting the Rollers

    I have a dual axle EZ Loader trailer and my tongue weight is a little light. I am looking to pull the boat a little further up but the end of the boat is right at the back edge of the rear rollers. Look at the picture I've attached. What I'm thinking is for the rear rollers is to unbolt them...

    Clicking in foward - 50hp

    Hi All, I'm putting a 50hp Mercury (early 80s - 83 maybe) back on my grandfather's boat. It's been off since 2000. I've attached everything and just finished the cables. Before I attached the cables it was in neutral and the prop spun both ways like it should. I would click it into reverse...

    Tachometer Issue

    Hi All, I have an 1986 Merc 5.7. The motor runs great. I just replaced all of the gauges because most of them didn't work and the one's that did were on their way out. The tachometer was one that didn't work. I got a set of Teleflex Amega gauges and the tachometer is not working properly...

    Copycat Covers

    I'm in the process of having a memorable experience dealing with copycat covers and thought I would pass it along so that other people considering using them have this information before deciding to move forward or not... I have an 86 Wellcraft Elite 200 and had done an online quote inquiry in...

    Hi all, Is there any links to downloadable service manuals for Merc outboards? I have a early-mid 50hp that I'm trying to get going after not being used (but properly stored) for 10 years. Thanks!

    New outdrive - extreme vibration

    I just had a new SEI Alpha 1 Gen 1 outdrive and a new gimbal bearing installed by my certified Mercruiser mechanic and took it out today to start the break in. I got massive vibration when I put it in gear (forward and reverse) and did anything over than putting along at a mph. Any ideas...

    Bow seat back mounting hardware

    Hey... I'm re-upholstering my bow seats and side panels on my boat. The seat backs and panes are attached using these plastic double sided things. Anyone know where I can get replacements as a lot have broken removing the panels...and what is the correct term for them? Thanks! Mark

    1986 5.7 Alpha 1 outdrive problems

    I have a 1986 Mercruiser 5.7 with an Alpha 1 outdrive. The last time I took it out it developed a problem. It stalled. When I put it in neutral, started it up, it fired right up no problem. But when I shifted, it stalled. Tried again...same thing. Started again, pushed in the throttle to...
