Hello all,
So yesterday I took my new to me 1988 fourwinns horizon 200 with the OMC 4.3L and cobra out drive for a test ride. Boat ran great coasting through the river at about 10mph. Once I got out of the river I opened it up and the boat was cruising great at 30mph for about 8 minutes, then I slowed down and was coasting back towards the river at 10mph again and the engine shut off. I immediately tried to crank the engine over and all I get is 1 small crank. The motor wouldn't turn over and it sounded like it was locked up. At this point I'm thinking the worst. I open up the engine cover everything seems normal, warm to the touch not hot, no smoke. I should mention now that through this whole ride the temp gauge stayed at 0 which made me a little bit nervous. So after inspecting the engine nervously for 10 minutes I decide to try and crank her again and she started turning over ! So I pumped it and gave her a little gas and she fired back up. Engine sounded good didn't see any issues at all. I was pulling my anchor up and was going to head back in but after about 3 minutes of idling the engine made a strange noise almost like it was gargling which lasted 2 seconds and she shut back down. I tried to start her up again and she turned over fine but took a couple tries to start back up which when she did I just killed the motor and called for a tow. 15 minutes later I tried again and she cranked reaaaaaaal slow then after 10 seconds of cranking she was locked back up. My tow arrived and we brought her back to the dock and I tried cranking her 1 last time and she fired right up and sounded great for about 20 seconds and then I shut her down and loaded her up. Anyone have any idea what's going on? I sure don't, this is my first boat. I'm thinking maybe it is overheating and that is why the engine seemed to lock up? Also the thermostat staying at 0 makes me skeptical, also at 1 point after the boat was sitting for 10-15 minutes without running I happend to look at the temp gauge and it was at 130 degrees and that was the only time it wasn't at 0... I'm lost anyone have any ideas?
