    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.

    I ended up getting the pdf. it was easy, I used PayPal. I agree with those wanting the book the carry around, I have other pdf manuals and some printed. I'll get by with what I have.

    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...

    video of my motor idling

    thanks for the reply. I'm getting mixed feedback on this so I'm not doing anything too involved. as long as I'm not damaging anything. I've been sent down some rabbit holes before. regarding the idle speed, I don't believe it is adjustable on this motor.

    video of my motor idling

    I'm back at this again. here is where I'm at. 1. compression is at 125 on all cylinders 2. I tested for spark today and found good spark on all cylinders 3. I removed and cleaned what I believe are the low speed orifices on the carbs. 4. I pulled the plugs and checked the gap. So I'm not...

    Center toon shorter

    I don't see this causing problems, you'll just have to give it a try. It may cause the motor to sit up a bit higher out of the water...

    Volvo penta aq125a

    I'm pretty sure what you're calling the workshop manual is the only service manual available. approximately 75 pages? Did you set the points with a dwell meter? recheck the timing after adjusting the dwell?

    Anybody have "old" pontoons?

    I bought our '96 pontoon from the original owner roughly 12 years ago. we used it as is for a few years until the opportunity to keep it at the inlaws cabin on Leech lake,mn. I've done a bunch of work since, new helm, all new upholstery, added a third tube, new carpet and decking, etc. My...

    1 or 2 PDS bearings in my Volvo 270 outdrive

    there's no way to know what parts you need until it's broken down. just be careful, you can spend a lot of money without ever using the boat. it sounds like you have a thru hull water intake. if it works, I would leave it. dont fix what works, being 50 years old, I'd bet there's more pressing...

    Reverse Lock Mechanism Help: VP 280

    to me, the pawl in your pic looks fine. I've never replaced mine so I can't say whether or not you can replace them without pulling the whole assembly (which is quite involved since the assembly is held by the pivot tube). regardless of gear, can you physically pull up on the outdrive? the...

    Reverse Lock Mechanism Help: VP 280

    the pawls will catch in forward but should release if you hit something. so it sounds like it's working correctly. as long as it doesn't bounce up in reverse and it releases correctly when you tilt up, you're good to go.

    Older Ranger Inboard

    I reread your original post, didn't realize all the work you had done. I'm not real familiar with the Ford V8, but I'd imagine most 302s with a marine cam and marine electronics and accessories would work. there is no such thing as a marine specific block. some parts may be very hard to find.
