First i would like to say hello to all,I am new to this type boat and i am helping my buddy next door with his new purchase. He just bought (95?)speedster with 1 rotex 2 cyl engine with one dual carb. The boat was not running. The old owner said he had overhauled it ran it for 30 mins in a lake then it just stopped. 600 bucks later my buddy owns the boat and trailer. We pulled the engine apart and replace a broken crank, we installed it and it turns clean, fuel to the carb yet we lost the spark to the plugs it comes and goes we checked the small wire to the coil and it gets juice so we replaced the coil and still nothing. If you have any ideas before i buy a manual for his boat (WHICH I WILL DO ANYWAYS), Just to get it started so he won't feel so bad. He doesn't have to much money thats why i am helping him out.
