So I just bought a used 2007 Supra Launch ssv in April. Have had it out about 10 times now, with no issues, but it is getting progresively warmer here in southern Nevada and it was 105 degrees yesterday and we were running for about an hour and then shut down while we floated in a cove. I restarted it twice to reposition in the cove, started fine, but then it was off for about an hour and when I tried to start it again it just barely started then died. Tried to restart a couple more times but just wouldnt run. I remember reading about vapor lock, so I opened engine compartent and put a cool towel over the engine, i would have poured water on the fuel line , but did not know where it was. After cooling for about a 1/2hr it started and ran fine and surfed and played for a few more hours but I did not shut it down again till it was on the trailer. I did a quick restart on the trailer no problem. Engine temp was running about 164 degrees, is that a normal operating temp?
Anyone had similar issues operating in hot temps?
Elsewhere I have read about insulating fuel lines and was wondering what to use and do I just insulate the metal lines near the engine or the rubber ones also that are back near the fuel filter?
I also read a post somewhere else that said this is a known issue and back when their boat was under warranty Supra had the dealer put in a second fuel pump. Any thoughts or experience with that?
Thanks for the help.....Dale
