    fuel gauge sending unit test

    this test worked well. I had good steady resistance change through the motion of the float, so I think the sender is good. I'll have to check the wiring once I get back to the machine. thanks!

    fuel gauge sending unit test

    thanks for the reply AD. when the sender was hooked up, the gauge wasn't giving any reading. Is there a way to test the sender using a multimeter?

    fuel gauge sending unit test

    this should be an easy one for you "smart guys". long story short, Bobcat quit, seemed to run out of fuel. narrowed it down and figured out it was a broken pickup tube. pulled the tank, sure enough. The fuel gauge hasn't worked it 10 years so I thought since it's out, fix it. Can you guys tell...

    Resurfacing marine plywood decking

    CCA Plywood is commonly marketed as pontoon replacement decking. I used it when I replaced mine with no noticeable issues since then, roughly 8 years ago. I'm curious about these comments...

    Decided to replace the decking

    on mine, there was black butyl tape on the crossmembers where the plywood seams were. apparently to keep water from splashing up and through the seams. Not sure you need it if you're just making a floating raft. I was able to source the old style treated plywood, non corrosive, at a local...

    Resurfacing marine plywood decking

    when I wanted to replace the carpet on mine, I ended up replacing the plywood as well, mostly because the carpet was stuck so well to the ply. I had to remove everything anyway including the fencing and the channel around the edge. I've never heard of resurfacing plywood...

    Volvo Penta AQAD40A + 280 problems

    Welcome. the outdrive kicking up is a common issue but rarely is it the Pawls (hooks). You should get a factory manual for the 280, and study the tilt release system to realy understand how it works. there are many variables. I can't help with the steering, mine was always a bit sloppy as...

    Adding third toon

    if you raise the stern by adding a middle toon, you better have room to adjust your motor down. If not, you're going to regret the whole project.

    Adding third toon

    when I added my third tube, I also upgraded my trailer from a scissor style, which doesn't support the tubes at all, to a two bunk trailer. the middle tube hangs free, while the outer tubes are supported. The middle tube is not that heavy, I'd say 125 lbs, never weighed it. I only trailer...

    Adding third toon

    if your new log doesn't have a built it transom for your motor, keep the new log in front of the existing motor pod. That's what I did.

    cooling system

    If it is a volvo version of the 351, its model name is AQ240. Is it overheating?

    AQ125a overheating

    the aq125 is supposed to run at 180-190 deg, it has closed cooling. set the points with a dwell meter, then readjust the ignition timing every time you adjust the points. you also may want to try a prop with less pitch to help get up on plane.

    pdf service manuals

    thanks for the replies. The manual I need is for my 2000 90hp johnson. I checked the link Scott posted, and they do have the manual. it's $100+, and I have to wait for shipping. when I saw the Pdf version for 19.99, my wallet was happy and I can have it right away.

    pdf service manuals

    can't find a service manual for my motor. Has anyone ordered a pdf version from Watercraftmanuals.com? they have many in pdf form. Just don't want to get scammed.

    video of my motor idling

    yes, its run just like this for 12 years, but now I can't remember what I did with the idle mixture screws when I rebuilt the carbs. I may have left them since they are not specified in the POS manual I have. it's been a great motor.

    video of my motor idling

    not sure what you mean by cold idle, but when started cold, it idles high for a couple minutes, then idles down to between 800 and 1000 rpm in neutral.

    video of my motor idling

    this, you may be onto something. Unfortunately, my nonfactory manual does not have the correct info about my motor. it doesn't think my carb has the idle mixture screws, but it does. does anyone have a good manual that has the correct initial setting point for the screws?

    video of my motor idling

    I misspoke the idle is adjusted by the timing. Not at the Carb. I don't think the idle adjustment is the issue. it idles fine but rough, on two cylinders you said.

    video of my motor idling

    thanks! I've searched for a factory manual for this motor on occasion with no luck. with the exception of a slightly rough idle and a bit more vibration up to 2000rpm, the motor runs great. it has excellent throttle response with no hesitation at any time. I may try a different plug and see...
