    This is one of those areas where there are varying theories. The theory I hold to is that the Raw Water Pump (RWP), as a positive displacement pump, will suck the heck out of anything in its path. The nature of this pump makes it self-priming which is why it’s used in marine applications. And...

    Fuel return

    If your fuel tank pick up tube’s bottom screen is plugged up, it will require a through tank cleaning, not just a shot of air (and agree bad idea). With your dual engine set up you have the best troubleshooting arrangement possible. Start at the Fuel Pump side and swap the hoses even if need to...

    Fuel return

    Ok so not some funky dual tank mod with a single engine. And the elevation works > i.e., if one engine can pull from its tank then the other engine should be able to as well. So back to the bad anti-siphon valve, a weak fuel pump or some sort of other blockage that your hand siphon can overcome...

    Ah, i see. There is no impeller in my SX-M outdrive. What do you have?

    Fuel return

    If you can pull fuel with a hand siphon pump but the fuel pump seemingly cannot, then the anti-siphon valve on the tank may be an issue or the fuel pump is. It’s confusing that you have a dual tank set up and I am also confused as to why the tank vents have a “Y” in them > perhaps this is...

    Starter for V8-300-C-A

    “Shocking” the area where it threads into the block as well as the starter housing around the bolt head by using a ball peen hammer and whacking it can help loosen it. If you have a pneumatic hammer with an anvil end, use that. And agree an impact wrench is much better for breaking loose bolts...

    I have posted what I have learned to date (link). It started off as a request for the upper seal of the distributor. Once my investigation is complete I’ll post the finding under a new post. For the muffs > it seems that most shy away from using them on the VPs. There should be on your engine a...

    You have the infamous plastic distributor housing. There are several fixes. One is getting the Dorman 90449 Vortec Distributor Repair Plate (link). I personally do not like this option as you can lose it into the bilge during cap replacement. But it works. Two: if the holes are not too baldly...

    2003 4.3gl PEFS overheating, please help

    There is no air bleed. Did your previous Raw Water Pump (RWP) impeller disintegrate due to the corrosion inside the housing? Was this the first start of the season? Also, you said “replaced the impeller and pump”. The rubber impeller is in the RWP on the crankshaft. Did you also replace the...

    VP SX oil leak?

    While there are procedures for pressure testing its involved with needed fitting and gauges. Instead pull the boat and once all dry wipe down all the fitting into the cylinders as well as making sure there is no oil residue on the cylinder rods. A difficult place to get to is where the cylinder...

    Time for Riser & Manifold > VP or Barr?

    For the Riser, I was planning on using the Permatex Aviation (80019) material recommended by others, but the dynamic of putting on the risers mentioned above precluded that. For the Manifold, back in the 70s, when I was first learning to rebuild engines, I understood that putting gasket sealer...

    Distributor installation – is this right?!

    Well, this is one of those cases where I must have been seeing things. I got back to this ‘issue’ and pulled the dist. and did a through inspection. No shinny areas where there should not be indicating something rubbing that should not be. A scope inspection of the hole showed all is as it...

    Volvo Penta Drive Belt - Lots of dust and quickly wearing??

    Just thought of this: also post pictures of old worn belts focusing on the area of the wear: the edge, the ribs, etc. And in the engine compartment where is the largest collection of belt dust. This should help narrow down what the issue may be.

    Volvo Penta Drive Belt - Lots of dust and quickly wearing??

    CaptnO, Assuming pulley is not loose on the shaft, runout is caused by either a bent pulley or a bent shaft or both. Thus, fixing can be replacing the pulley only or the entire pump assembly. However, I re-read the entire post and three things stood out to me. In post 8 Lou commented that in...

    Time for Riser & Manifold > VP or Barr?

    Finally! I was able to get back to the boat toady to finish off the Manifold and Riser job. While all ended up well, great in fact, there were a few lessons learned. So, posting here for others if they undertake this job. Overall, it’s a straightforward job with no special tools needed but they...

    Volvo Penta Drive Belt - Lots of dust and quickly wearing??

    If the pully can wobble on its shaft, like it’s a loose fit on the shaft > that is an issue! If the pulley is tight on the shaft but wobbles when you turn it (called runout > i.e. as the pulley is rotated it traces a back and forth profile (without the belt on, and you can turn the PS Pump...

    Fuel return

    I was able to get back to another job on my boat today so took off the access cover for the fuel tank and took pictures. Hope this helps.

    Dubs, good point I was focused on the engine side. Jrato: The full fill ‘cap’ typically also has a vent line and the two hoses (a large fill and smaller vent) are routed to the cap. See this link for some pics and how they work.
