    Omc 351w king cobra ignition conversion

    That's the Cap they use on the internal coil units...they also have an EST style distributor (external coil)...though I've never installed one on a boat engine...

    4.3 Mercruiser - randomly dies

    Way back in time, we used to use a 'freeze spray' when troubleshooting many electronic devices...haven't looked for any in years but it might be worth trying, especially it you think the part(s) in question have a repeatable 'fails hot then cools and behaves normal' behavior.

    New Crusader Owner needs help with engine tuning/timing

    good on the old oil...bummer on the WX... The Merc S/S elbows had a short production run so hard to characterize the lot of them...that said, I got over 15 years on mine...only gasket weeps since. I couldn't say positively on the compatability with the crusader manifold but surely wouldn't bet...

    Gasoline Vapors in the Salon

    make sure you use the proper marine rated hose for what you change...and the AWAB hose clamps are about as good as it gets...

    The distributor is their standard designs - they will set it up for whatever timing curve you desire when you purchase it. Like Lou said, the EEM parts are very hard to find and are priced accordingly...I'd go DUI (over EST), if it will fit, soley because you have flexibility with the timing curve.

    Gasoline Vapors in the Salon

    hopefully, the surveyor has one of the professional accreditations?? I'd discuss the situation with him and see if this is 'new'. There should be something clearly stated in the report if it existed when it was surveyed. Its possible some work was done and something was missed in the process.

    New Crusader Owner needs help with engine tuning/timing

    the oil dipstick...if the engine gets frequent use, little water may make it into the pan. Its a rise in the oil level due to the water in the pan...you can also see the water once enough gets into the oil. could be raw water on the plugs/in the cylinders or corrosion - it the engine was run...

    New Crusader Owner needs help with engine tuning/timing

    poor choice of words on my part... if you have only the elbows (no risers), then only the elbows should need the regular maintenance (replacement). Depending on the use and the operating environment, they typically have a 5 year service life. Some people have extended it a couple years with...

    New Crusader Owner needs help with engine tuning/timing

    so they are fresh water cooled - real good, especially in FLA... Do you have any maintenance history? Specifically interested to see if the exhaust risers have ever been changed?

    New Crusader Owner needs help with engine tuning/timing

    What's the serial number of the engine? Have you pulled and checked the spark plugs? I'd say the timing, if it is consistent, is in the realm of the original specification - what manual are you using? You should NOT run the engine above idle when operating it off of a garden hose...in the...

    454 carb engine wants to backfire/die after 20 minutes, only under load

    as stated previously, (assuming the described conditions are accurate) this describes a fuel starvation issue. Starting a new thread, with your specific details, may yield something worthwhile...

    454 Fuel Pump/Pressures

    I am certain both Crusader and Marine Power had TBI equipped engines that had at least two different operating fuel pump pressures. That they may map to a specific version of MEFI controller is coincidence, not a consequence. (Marine Power refers to these as the 9 and 16 PSI TBI systems.) The...

    Winterizing closed cooled 5.0

    FWIW, the hydrometer will on assess the concentration of antifreeze in the coolant mixture...you should also measure the pH, at a minimum.
