    Major engine malfunction today and could use advice on next steps

    Thank you for that. I have a cap and rotor distributor cap the crab style. My coil looks like a small device with some fins. It look like an old fashion coral the shape of a small soda can. Are you saying I could’ve possibly cooked the coil or the cap and rotor? I’m going to check for spark...

    Major engine malfunction today and could use advice on next steps

    Had four amazing days with the family at Catalina island and upon returning today had some major issues which led me to be towed for the first time in five years of owning my 1997 Parker with a 2007 Volvo penta 5.7 G.I. – F. I was heading back, cruising at around 3200 RPM and all the sudden...

    Bogging in relation to distributor

    It’s been super easy to get a free one each time. They don’t even bother looking at what’s wrong with it because they know it’s got a lifetime warranty. If they ask, I just tell them that the amount of corrosion was surprising. The first link points to a distributor cap that has brass. The ones...

    Bogging in relation to distributor

    The line of products is called Echlin and they carry a lifetime warranty so the counter people are always very cool about exchanging it. I’ll try to find the article that talks about why Napa developed the special style crab cap to address the issues that plagues the other ones...

    Bogging in relation to distributor

    I switched out those cap and rotor and ran the boat for two straight hours at around 3200 RPMs and did not have any bogging. Because these cabin rotors come from Napa, they have a lifetime warranty and I’ll probably just swap them out every 3 to 4 months regardless of condition. It’s kind of a...

    Bogging in relation to distributor

    Here’s a follow up. I change both the cap and rotor and for now the bogging seems to have disappeared. Around 75 miles today and for the first half stay right around 3100 RPMs and only return home bumped it up to 3300 RPMs. No bogging occurred at all today, this cabin rotor is made by NAPA in...

    Bogging in relation to distributor

    Boat is an hour away but will post soon. Should I switch over to a cap with brass? Here’s the type of rust that is starting to get on the bolts and why I thought it was a smart idea to pick up a very expensive part for such a low cost

    Bogging in relation to distributor

    Cap Just sitting out for like 4 to 5 months. Is this enough to cause a bogging situation?

    Bogging in relation to distributor

    Thank you for the help. Ill try your suggestions. The boat was from the east coast then Texas and had some corrosion when I received it. I store it in dry storage ( an open lot here in CA) but close to the shore where there is heavy salt air from large surf. The manifold I have shows some...

    Bogging in relation to distributor

    1997 Parker 2520 with a Gi-g 5.7 New block installed 2007 based on the casting numbers. It is the crab style cap. 700 hours. Low pressure, idle psi, and high pressure taken on the rail are at spec. And at 3000 RPM the fuel pressure remains within spec. I found an incredible deal on an intake...

    Bogging in relation to distributor

    Just posted below. And to clarify if I back off the throttle from the bogging and let the boat just idle for 20 seconds it can ramp right back up to 3000 RPM I might not bog for five minutes or 15 minutes.

    Bogging in relation to distributor

    I’m really not sure how to answer that, but it is the crab style cap sitting on this distributor If I did need to order another one, would it be an automotive one or a special marine one?

    Bogging in relation to distributor

    I have had a bogging issue for close to two years. It seems to happen above 3000 RPM and can be random. I have done everything to the fuel system that would be related to bogging. New fuel lines, fuel pump, running on a spare tank, removal of anti siphon valve, change filters, and fuel pressure...

    Dealing with bogging for too long and need help because I've done just about everything!

    The current block is 100% GM. It is fuel injected with the Vortech style intake manifold. I do not know what the original block was in 1997 or what was on it. For whatever reason, the previous owner decided to put in the new block in 2007 and my assumption is that many of the old parts like...

    Is this the knock sensor?

    Dealing with bogging for too long and need help because I've done just about everything!

    I will do another compression test. Roughly one year ago, I did a compression test and the mechanic noted that there was just one cylinder just barely under the 10 percent threshold. For my own mechanical knowledge, let’s say there was one cylinder that had really bad compression either due to...

    Bogging also happens with fuel cap off.

    I replaced the anti siphons with a regular fuel barb. No bearing and spring. Problem exited before Racor installation.

    1997 Parker 2520 with a Volvo Penta 5.7 Gi-f 750 hours. Block is from 2007 so maybe the heads and manifold and other parts were transferred over after the 1997 engine was replaced. Purchased the boat a few years ago and had a new VP fuel pump put in. I have never heard it whine. Bogging tends...
