    Carter Universal Fuel Pump Problem?

    My boat has 2000 350 carburated Vortecs. The fuel pumps are Carter Universal 5.5PSI. The port engine started dying after running at idle for a few minutes. I found the 50 AMP main breaker had tripped. I reset it and it was up and running again. A few days later it did it again. I reset the...

    Starbrite Star Tron fuel additive

    Has anyone had any experience with this fuel additive. They have products for gas and diesel. It is enzyme based and sounds like the greatest thing since sliced bread if it works. The claims are "up to 15%" improvement in economy; one year of gas and two years of diesel stability; carb...

    Kohler Gen-Set problem

    I'm not sure this is the best forum for this issue, but it is an engine problem. I have a Kohler 6.5 CZ23 generator. It recently has been hard or impossible to start. I've had the local authorized guys down to work on it. They have replaced a couple of things that probably needed to be...

    Spark plug gap on carb vs. injected engines.

    My boat has 350 vortec engines with EST ignition and is carbureted. The manual says to gap the plugs at .030", while the TBI and full injected versions, using the same ignition system are gapped at .045". I called the factory and they confirmed this is correct, but the tech couldn't explain...

    Replacing shaft packings in the water

    Have any of you replaced shaft packings while the boat is in the water? I won't need to haul the boat for bottom painting for another 2 years but one packing is nearing the end of it's adjustable range. My thought is to dive under the boat and press molding clay around the shafts were they...

    Transmission Cooler Zincs

    I have twin 350 GM's attached to ZF Hurth vee-drives. The tranny coolers (simple torpedo shaped raw water heat exchangers)do not have zinc anodes (at least not that I can find). The boat is used only in salt water. It makes me nervous <br />having trans fluid running through an un-protected...

    Sticking secondaries

    I have twin Indmar 350 GM vortec engines (1999's) with Holley 4V carbs (I'm guessing they are 4160's)in a 34 foot ocean boat. As the boat is a fuel hog, I stay out of the secondaries. However, on occassion, when I test the secondaries they are stuck. They are vacuum actuated. I can free them...

    Force 15HP won't hold higher rpm

    I have a 1987 Force 15 HP with coils and points ignition system. The engine is very low hours, but sat for about 5 years. Engine starts and idles fine (after cleaning the carb). It will rev up fine but then quickly lose revs (in neutral or in gear). I cleaned the carb and checked the fuel...
