    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...

    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...

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...

    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

    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...

    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...

My F80 is getting a little water in the oil and due to a previous water intrusion issue that I fought with on another outboard I'm trying to figure out how the oil pan is mounted.... in case I need to inspect/change it out. The...

    Fuel Pump Test?

    1999 75HP Enduro - I just saved this outboard from the dump. The owner said it was overheated and running rough before it died. Turned out that it was not reliably firing on one cylinder due to a damaged wire going to a coil. I cut and repaired the wire and got the outboard running fair. I...

    Brand Recommendation

    I'm interested in finding a cheap ($500) 15-19' fiberglass boat that I can mount a Yamaha 75 Enduro outboard on to use for inshore fishing in NE Florida. I'd like to find a typical runabout that I can take the windshield off of and add a seat in the back to run the tiller. What would you guys...

    Bunk Slide Alternatives?

    I had the ironwood pacific brand on my old trailer, they were great, but occasionally cracked. In my opinion, all the brands are all too much money for what they are. Around $200 for my application. (Four 12' 2x4s) Unfortunately since I live in AK I haven't found anyone who will sell me...
