We just sold our 2002 glastron gx185. The woman I sold it to, does not have any former experience with boats... she's been on them , but never owned... she has friends who have boats and work with boats. We did not summarize the boat before handing it over to her... we took it out for a test drive, approximately 1 hr. A couple days later, she and her husband take it out... approximately 2 hrs... she says all was fine until they docked the boat, then the engine exploded and goop spewed out. Her mechanic friend is saying it's a cracked engine block due to improper winterizing. 1st off, we definitely winterized the boat back in October, even though we brought it down to Southern California where we do not get freezing temps... we winterized it anyway. When I took it back up to lake Tahoe, by the weekend, it was snowing, but im told it would have to be for a few days in pretty cold Temps, we were in high 20s low 30s for one day. Plus, my new boat which was also in those same conditions without being winterized, had no problems when we took it out right after the snow. Im wondering what else could have caused this... could it be something else other than a cracked engine block?
