    Good morning. Thank you for the information. The marker that stabilizes at idle at 45 and at high speeds fluctuates from 0 to 60 is the PSI (attached photo). Do you know how to test the relays? I will check the engine harness connector to the ECM harness. Thank you very much for your...

    I only sail along the coast, short distances and I don't go over 3000 rpm. This is my first boat, my family and I really like it and due to my sailing style, it serves us well, even though it doesn't have a high-powered engine. In any case, I'll take the advice of someone with more experience...

    Regarding the distributor, an important piece of information is that in November/23 the distributor was showing oil residue, at the time the mechanic said it would need to be replaced. I found the original part only in one place (in Brazil) at a frightening price, so I bought a similar one...

    Ok, I understand the difference between compression and leak tests. As I said, the compression test was performed with the values sent in the initial text. According to the technician, only one cylinder is below the expected value, but this, according to him, would not be a reason for the engine...
