    Mercury 80 won't crank with plugs installed

    Updating in case it helps someone else. Worked with Mercury techs today to diagnose the issue. With the plugs removed and engine oil drained (there was some gasoline in the oil), the motor cranked easily enough but a lot of fuel was spurting out of cylinder 4. We swapped an injector to rule out...

    Mercury 80 won't crank with plugs installed

    Thank you very much for the quick reply. Motor last started in shed with muffs in Jan/Feb and run idle for 10 mins to keep things operational. Boat has not been in the sea since. Assuming issue is hydrolock (and potentially bent rod), why would removing spark plugs from cylinders allow...

    Mercury 80 won't crank with plugs installed

    Twin Mercury 80 HP 4STK (2007) not turned over in 2 months. Hot climate and stored under shade. Port engine fires up immediately. Starboard engine does not crank. Starter engages but cannot turn flywheel. Attempted to manually turn flywheel but very stiff. Removed all 4 spark plugs and manually...

    Starter clicks but won't turn

    Starter Wiring Diagram Starter Wiring Diagram So I found this while moving through the OEM prescribed trouble-shooting steps. It's pretty much identical to the existing wiring set-up... it even has the metal strip (tagged 'G' in the my pic) which connects A and E. The only difference I...

    Starter clicks but won't turn

    Re: Starter clicks but won't turn : ) I'm positive the wiring set-up has not been changed since when the engine was last run. To make life a little easier, I've tagged all 6 terminals in this pic: A: unused terminal on starter relay B: +ive cable from battery C: from ignition switch D...

    Starter clicks but won't turn

    Re: Starter clicks but won't turn Interesting observation... I was thinking about that myself. But, bear in mind the engine was running fine with this wiring set-up prior to storage. I'm not saying this wiring is optimum, but that's how it's been since the motor was purchased (used). I'll...

    Starter clicks but won't turn

    Update #1 Update #1 OK. Starter removed. Shaft rotates quite easily. I think we can toss out any jammed scenarios. Electrical trouble-shooting now... will keep you posted.

    Starter clicks but won't turn

    Hi All, Re-commissioning an engine which has been in storage for some years. Crankshaft is rotating and pistons are moving quite normally by rotating the flywheel. On attempt to start, the solenoid engages (or at least I can hear some relay clicking) but no further movement. After repeated...

    Groovy Drive Shaft

    No prior experience so must ask: At what point do grooves on the driveshaft become critical? The pic shows the upper shaft from a '97 90hp. Arrows indicate worn areas - caused by contact with the seals (impeller hsg + bearing hsg). In your opinion, do I need to replace this shaft? If not, then...

    OMC > BRP Part Numbers - Help!

    Hope this isn't in the wrong section of the forum. I'm having difficulty searching for Evinrude parts since many websites/catalogues are using a newer numbering format. Example: I need a new prop shaft. Both the BOATS.NET and the BRP Official Catalogue list this part as: 0436834 The aftermarket...

    Are new shims a must?

    Hi all, Need to replace the prop shaft, so need to remove the driveshaft. Two questions: 1. If the driveshaft is removed and then reassembled without changing anything, does it still need to be shimmed with the shimming gauge tool? 2. Is it advisable to re-use the same shims or should I...

    Trusting a used prop shaft

    Hello all, I've borrowed the pic from an existing thread (hope the original author doesn't mind) since my outboard met with a similar accident. Skeg took the brunt but while the prop was severely bent, it didn't break off. http://forums.iboats.com/showthread.php?t=433141&page=1 1. I stripped...

    Mystery Hole (Probably a stupid question!)

    Hi, Can't seem to find any info on this hole as shown in the picture. I've checked various schematics but it is not detailed or even mentioned. The lower unit belongs to an Evinrude 90hp (1997). Is this for a pitot tube? But all pitot tube references (as researched online) are for the 115hp...
