  1. Rebuilding the Volvo MD7A

    Gear & Maintenance
    In my continuing efforts to finish rebuilding the Cape Dory 30, I tackle the sticky inboard rebuild. In my case it's the Volvo MD7A. With parts not being made, it's a challenge finding them but in my experience but for the most part a thorough online and offline searching yielded me results...
  2. Volvo MD7 Overheating but exhaust water cold?

    I have certainly seen several threads on the volvo MD 6/7 engines overheating, and I am hoping some of those folks who have dealt with this before might be able to recognize my symptoms to help me narrow down what needs to be fixed.

  3. Volvo Penta MD7A fuel problem

  5. MD7A or parts for sale

For the long term, I'd need to remove it from the boat for rehab and since I'm outsourcing all the work it just doesn't pay for me...
  6. MD7A Exhaust Manifold Port identification

    I have a MD7A on my Cape Dory 28. I just got it 3 months ago and replaced the impeller, cleaned the thermostat housing and removed the exhaust manifold due to the large amount of debris. There was quite a bit of clogging so it was worthwhile. I believe I've figured out the flow pattern from the...
