make 89 Sunbird model corsica 175 ok got the make model year listed now for the problem ..installed new starter then took gas cover off to check out the fuel hoses. see the top of the sending unit and the fuel outlet covered with crystals similar to rock salt or sugar . boat is only run in fresh water entire life. kept covered when not used on trailer. well took wrench to the fuel line out let it broke off at base where the gas line snugs up to elbow of gas tank connect and gas tank is solid white plastic.. any ideas what the crystal dust is ?? and cause never seen this before all the 10 yrs have owned the boat thanks! also put in fresh rebuilt starter from local shop my original starter and havent put any power to it , as seen the above fuel tank problem, but i tried turning the engine over with a socket and breaker bar on the crank shaft and engine wouldnt turn over.. so going to pull starter off and try manuel turning engine, maybe the starter shop put on too long of part that goes into flywheel ?? he did mention something about putting on a longer something??? maybe the little gear in bendix i dunno ?? thanks guys be back in a while to take starter off.. this messes up this weekend 1st chance to take boat to lake
