Great forum hope it works for me like it usually does. I just bough a 2002 four winns horizon 180 with the 4.3 v6. Previous owner had all paperwork showing maintenance since he bought it brand new. Test drove the boat for at least 30 mins all gauges showed no problems. Checked the oil while driving and it seemed fine no water. That was two weeks ago went out today to change the oil hooked it up to the water hose to get it warm. When I sucked it out of the dipstick tube it was grey. But on the dip stick it looks fine. I changed the oil and filter twice just to be sure where could the water be coming from? Between the two oil changes the water was running and I checked to see if water was getting in the oil pan via the dip stick and it was not so any suggestions will be greatly appreciated.
