    1997 Johnson 25 J25TKLEUR

    This engine has the optical ignition. The owner prior to my customer removed the rect/reg. Owner states that he runs engine a while THEN it shuts off completely. And when he tries to restart there is NO SPARK on any cylinder. After it sits about 20 minutes, it magically fires back up. He...

    VIN table

    I was trying to find the year of a Yamaha the other day. I was on boats.net, and their listing is by model#, but you need the year which I didn't have. Even on Yamaha website, you can find it by model BUT it still doesn't show the year. I emailed boats.net and was sent this link...

    1996 Johnson 150 Faststrike J150GLEUC

    Initial problem, engine wouldn't start, usually, but sometimes it would, very random. Checked spark etc, wasn't getting any. Tested out to be power pack. Since I don't have the optical Tester, I replaced PP with one from CDI which came with new optical sense as well. It is ALSO designed to...

    1997 Yamaha 25 C25MLHV

    Most motors I deal with have a typical float needle that clips on float or just sits in seat base so float tab makes it level when closed. This one has the spring inside the needle with about a 3/16" needle sticking out. This needle contacts the tab on the float, normal stuff. Trying to set...

    mercury 50,500 shift cable latch

    On this motor where shift cable attaches to engine shift rod slide, is this latch able to be replaced without pulling engine? The diagram is crap and looking at it on engine I really can't see how it comes off? On the rear end there is a bolt which I assume is holding it on the actual slide rod...

    Mercruiser 1A600801

    1. On the carb on this model, is piece 25 a special tool? 2. Also, is this mixture screw one that is hidden behind a removable plug or do you have to drill out the cover over it to get to it? https://www.mercruiserparts.com/bam/subassembly/31842/12834/80 When I looked at it a few weeks ago...

    Yamaha150 1984-1990 wiring diagram needed ASAP

    I cannot find a correct parts list for these engines. None of them actually show the unit mounted in back between the 6 coils. Like this page, but no pages actually show the big box in back behind the cover...

    Fishing here on this one. Customer brought his boat over this evening and these are the things he mentioned. One day he had a low oil alarm. Added oil and it cleared. Good. The next problem was this one. I haven't worked on a Optimax since school, 10 years ago. He said he was running...

    1991 Mercury XR6 0C100861-0C239552

    This motor has no spark. Mercury book tests dcv at black/yellow wires on both switch boxes with wires connected. Should have 100-240vdc @ 400 rpm etc. I have 0 vdc. So then book says disconnect black/yellow from both switch boxes and retest. (1) If now normal, it is a wiring, ignition...

    Mariner 25hp 0D003174

    I've tried everything I can think of on this one. When I get it started it runs a few seconds, even sometimes up to almost a minute then dies. The carb had been cleaned twice, injector rebuilt, carb float set correctly and fuel pump rebuilt. The electrical resistance checks all good, had...

    Hey guys, my customer had a reverse problem (no reverse). He said he threw it in reverse with high rpms taking it off the trailer. The shifter is the old style with no Neutral lockout button. Anyway, I looked at it today. Nothing visually wrong. Shift cable is moving thru the full range etc...

    Hey guys, got a call today to troubleshoot lack of rpms and no idle etc. I connected my timing light to all 4 wires and they all spark. I checked the stator and trigger voltages - all great. I checked the switchbox voltages to the 4 coils - all great. I checked grounds and removed and tightened...

    Hey guys, working on this motor the other day which has no spark. Narrowed it down to what I thought was the power pack and replaced it, still no spark. Stator voltages and resistance are all great. Power pack to the coils I get like .8 to 1+ volts and that's it. Sensor wheel is good and I...
