I have a 1997 Dynasty 19 foot with a 4.3L Mercruiser engine. I just started to use the boat after it has been in dry storage for 6 years without use. It was winterized before stored. The boat was working great before. Here is my situation now. The boat starts off fine. It dies sometimes at the beginning when put in gear. After a while it runs fine at high speeds. When slowing down from moving to neutral the engine turns off. After a while of use, the engine at low speeds will pulse the RPMs. The boat will literally pulse back in forth as long as i keep it at low speeds. Typically at high speeds it runs fine but once the boat wouldnt accelerate and wanted to die. Typically after it dies it take 5 mins to restart. It feels like the boat isnt getting a constant flow of fuel. I have put fuel cleaner in the boat and new fuel. I am heading down to the lake this weekend and want to have some supplies to try and fix it. I have been reading on the forms and hear that it could be a few things including coil, fuel filter, spark plugs, carb, and vapor locking. Any ideas? Which things should i try to fix first. Thanks.
