My son has a 89 bayliner with a ford 2.3 motor with a carburetor. It overheated than ran normal, overheated, etc. Brought it to a shop and took care of the problem. Ran okay afterward as long as you SLOWLY accelerated to top speed. Had it looked at again with no luck so after taking it out again using the SLOW acceleration method and getting it up to full speed for about 5 min. it begain to slowly loose power until it no longer ran and would not start. Checked the oil and noticed milky white mix. I assume the head gasket is blown because of the milky mix. Would that also explain the way it ran prior to dieing? I am thinking a simple head gasket replacement will take care of the problem? Any info. concerning the problem would be great - thanks
