    Co-pilot installation trouble

    I ordered a tiller kit to convert my remote control/electric start 1A3G312EK model 30hp EFI four stroke to a tiller steer and got the 898103A92 co-pilot kit with it. While I was attempting to install this kit I realized that the 8mm bolt/stud that screws into the swivel bracket was too small to...

    The subject motor is a recent purchase: Model Number: 1A3G312EK / Serial Number: OR568876 manufactured in 2013 It needed a fuel system overhaul and three new injectors but now that I have it running I'm looking to get a tiller kit for it. The motor is currently a remote control configuration...

    30HP Merc EFI Four Stroke Wiring

    I believe I have a Mercury-badged Tohatsu that I purchased used a couple weeks ago. I'm curious if I can get help identifying what connections need to be jumpered in order to get it to start for a test run on the stand without controls or a tiller before I spend a whole bunch of money getting...

    Questions about 30HP EFI four stroke

    This past weekend I purchased a used Japanese motor Model Number: 1A3G312EK / Serial Number: OR568876 manufactured in 2013 It was a remote control setup but the seller had no controls or cables so we couldn't start it. I did a compression check using the manual starter rope, inspected the oil...

    F25 Sudden Compression Loss

    After running fine for five hours, my 2002 F25 missed for a few seconds at half throttle, quit running when I slowed down to investigate, and would not re-start. Compression was an even 140psi prior to the issue, it is now an even 90psi on both cylinders. I've verified good spark, fuel, and...

    F25A Timing

    Aloha, I'm currently troubleshooting a 2002 F25A for a friend that is not running right above 1/3 throttle. The carburetor has been soaked and fully disassembled and cleaned and blown out with compressed air twice, valve clearances have been checked, powerpack and CDI have been swapped with...

    2002 and 2004 F25 power heads interchangeable?

    I have a 2002 F25MLHA that I'm helping a buddy with, it has gear case issues and we are also hoping to convert it to a short shaft. I picked up a 2004 F25MSHC short shaft donor motor with a good gear case. I was hoping to take the good power head off of the 2002 and put it on the 2004 but see...

    NS25C2 Revs Up and Down

    Well, opening up the CD ignition unit didn't work out quite like I had hoped. It's fully potted so there's no dremeling away around the edges and popping off the protective layer on this one. No reason for me to hem-haw about ordering a new one now. (I might have hammered on it a little once I...

    NS25C2 Revs Up and Down

    I was gifted the subject motor a few weeks ago and was told that it "surges". Well, I gave it a look over, checked compression and found 130 even on both cylinders, tested the kill switch circuitry, and verified spark on both cylinders. I then drained the carb bowl, flushed the lines with fresh...

    SUZUKI DF175 Tilt / Trim

    My buddy asked me to check out one of his 2006 175 four strokes, down trim works, up trim doesn't. Relay does not click when trying to trim up. Troubleshooting: - Disconnected each of the switches, first the pan switch and actuated the binnacle switch with pan switch disconnected. Negative...

    1980's Dixie CC

    This boat has a couple soft spots on the deck; one up in the bow and one behind the console. The transom has a couple lengths of aluminum channel attached inside the transom for support. I'm considering it for a project boat for a thousand bucks with a nice trailer. A question that I have is...

    F225 Rigging Questions

    I'm rigging a 2005 Mercury Saltwater Series 225 four stroke (Mercaha) with Yamaha controls. Ignition, tilt/trim, tachometer, warning horn, and warning indicators are all working. I ordered a replacement cam/throttle arm to change my 703 control box from a push-to-open throttle configuration to a...

    Oil Pump Issues

    I replaced the oil pump on my 1999 F80. I had the lower unit off when I did it. Now I can't get the lower unit drive shaft to go back together with the new oil pump shaft as I'm trying to reinstall my lower unit. I'm turning the drive shaft and can feel the splines contact but the shafts wont...
