    Connect alternator outputs of two motors to battery bank

    Thanks. This was my thought, too. I've left the small motor's 12V output disconnected until I sort this all out. Of course, I want to be able to charge my batteries while the large engine is off, so I'll need to sort out what extra hardware I need to combine the two charging sources. I realize...

    Connect alternator outputs of two motors to battery bank

    I have a Mercury 2-stroke 50HP outboard and a honda 4-stroke 8HP outboard on my boat. Do I need ti take any precautions before connecting the Honda's 12V output to my batteries so that it can charge them too? That is, do I need to do anything special when connecting two different alternator...

    '99 Mercury 50HP ELHPTO: carburetor idle screw adjustment procedure

    Thank you for the additional insight. This motor is on a 1974 Bayliner Quartermaster 17 (17'8" V-hull) that I picked up used and have been fixing up. I finally got it in the water yesterday (ocean off Victoria, BC) for the first time. I was really worried that it would be underpowered but it...

    Need help identifying 90HP V4 VRO model (1988 I think)

    It ran just fine, but I could see the throttle was only being moved about 25% with the control fully forward. I agree it isn't pretty. I want to slowly clean it up, but for that I would like to have the proper service manual.

    Need help identifying 90HP V4 VRO model (1988 I think)

    I agree that they are casting numbers, but there actually are several numbers there. What I am looking at (sorry for the blurry photo) are the two smaller 2-digit numbers on the casting, roughly lined up with the "vw-1" on the hose above them. "12", then a space, then "88". If you look to the...

    Need help identifying 90HP V4 VRO model (1988 I think)

    Hello, all - first post! I recently picked up a used boat that has a pair of engines. A 90HP Johnson V4 VRO and a Honda BF15A. The Johnson needs a little TLC (mainly throttle cable adjustment, I believe, but I would like to identify the engine. The welch plug inside appears to be missing, and...
