    Only starts at WOT

    Ok one more update (as I fall into a googling rabbit hole) is that today when I was working on some other stuff, I touched the ignition coil (is that the correct name for the part in the attached pic?) and it was HOT to the touch. I realized that the ignition was in the key-on position. Turned...

    Only starts at WOT

    ::update:: it now seems that I can get it to start with the throttle at about half mast (2-3k rpm’s?). But only after engine has been sitting for a while. Once warm I can’t get it to start again. I assume Scott Danforths advice about a rebuild still holds…but just adding in this update in the...

    Only starts at WOT

    With only intermittent use of the boat and a whole DIY engine swap that happened the first year, I feel like I spent the first 3 years “fine tuning everything”. There seemed to be lots of little issues that were slowly ironed out. Two years ago I seem to remember it finally running fairly well...

    Only starts at WOT

    Yeah it’s old :( the carb was rebuilt about 6 years ago and I don’t put many hours on it each year. Was hoping I didn’t need to dig that deep into it but I guess it’s time…

    Only starts at WOT

    I have a Volvo Penta with a 350 5.7. It’s a Rochester quadrajet carb. Hasn’t run in a year, and right now I can only get it to start when throttle is wide open (or close to wide open). I get one shot at it…if it doesn’t start that first time it won’t start at all without a little gas down the...

    Volvo Penta 3.0 stalling issues

    I know the boat sat for at least two years…but I’m guessing it actually sat longer. We replaced the anti-siphon valve, inspected the pick up foot, made sure the vent line was clear (the one up to the filler neck), and replaced the fuel filter again (this time with a paper filter instead of the...

    Flow reducer in Y Pipe?

    i'm a little confused by that parts diagram. It makes it look like only one riser has a line plumbed into the thermostat housing? Or maybe it's drawn in a way that you can't see that the second riser is also plumbed into it (see attached pic)? I'm assuming my boat is correct in that both exhaust...

    Flow reducer in Y Pipe?

    Sorry just to clarify some of the language and names of parts: water flow goes from pump to the manifolds and then the risers are above the manifolds? Then from risers to elbows and out the y-pipe? For what it’s worth I attached another pic that shows how it all attached to the y-pipe. If that...

    Flow reducer in Y Pipe?

    I can take a better pic tomorrow…but this one shows 3/4” lines I’m talking about. Where they meet (that little red T fitting) they combine into one line which runs into (or from) the Y-Pipe. It was in that combined line I found this little reducer Thanks so much for all the help!

    Flow reducer in Y Pipe?

    It’s a 5.7 block from a Chevy truck that was marinized. I don’t know much more about it. The outdrive is a 280 but the Y-Pipe I bought used from someone.

    Flow reducer in Y Pipe?

    Hey all. I have a VP280. I was replacing a piece of old hose (3/4” or so that runs off the YPipe and splits off to each riser) and found what looks like a reduced in it (see attached pic). Is that supposed to be there?

    Volvo Penta 3.0 stalling issues

    Working on a 2001 Volvo penta 3.0GSPA that sat for many years before I acquired it. Syphoned out the old gas. Put in fresh gas, seafoam, spark plugs, fuel filter, etc. First day ran great, but only ran at low rpm’s because I couldn’t get out to somewhere where we could open it up A month later...

    Steering helmet pin

    Hey all. I just installed a new-to-me transom shield/steering fork/helmet on my Volvo Penta 280 and am realizing that the bolt that screws into the outdrive is too small for the helmet (see attached pic). Is there a bigger bolt that I can get, or is this helmet a different style and not going...

    Putting a VP280 back together...

    Ah dang I was supposed to do this with it still hanging? Oof that was a mistake. Marina crane got it as close as possible and then I thought I was supposed to finish it off with the weight on the stringers. Ok I’ll have to try and schedule the crane again. So basically with it hanging I start...

    Putting a VP280 back together...

    Sorry to beat a dead horse on this but I don’t want to strip anything out. Right now the bosses on the pds are about 3/4” from the bosses on the transom shield. I know this gap will need to come in quite a bit. At what point am I counting on the bolts from the clamp ring to pull everything into...

    Putting a VP280 back together...

    Thanks Scott What I’m wondering about is putting the clamp ring back in though. I’ll push the motor as far as possible to the stern and align it, but I assume that in tightening the bolts the motor will pull a little bit to the stern? Is there a certain torque I’m aiming for? Or just get them...

    Putting a VP280 back together...

    hey all, i'm just finishing a transom and stringer repair/replacement, and wondering how i might best put this back together. it's a volvo penta 280 and an AQ260. here are two questions in no particular order: -rubber rings: does anyone have a part number for the rubber rings that are supposed...

    Adding a temp alarm

    I have a VP 280 (350 5.7) and there are no audible alarms on any of the gauges. I’d like to add some in but not sure how. I assume engine temperature and oil pressure are the two most obvious ones I should consider? I see an “Alarm For Engine With Audible Warning Kit” online for $45 that has...

    O-Ring Re-use and/or part numbers

    Hey all. I'm slowly putting a Volvo Penta 280 back together and trying to figure out what rubber gaskets should be replaced...and where to source replacements. Here's a list of the things in question: -Rubber Rings: Is the rubber ring that sits behind the sealing clamp the same as the one that...

    VP 280 Engine Alignment

    Am I being naive in thinking that if I get the stringers within 1/2” of their original height I should be able to nail it on the first shot? With the mounts set in the middle I probably have a good 3/4” to move in either direction…
