Yesterday while trying to get my boat back across the gulfstream from Bimini I was experiencing major engine malfunctions. Problem was with the hurricane in the Atlantic the seas were rough enough that I had to push it on across. No way could I stop and work on my engine in 6 to 7 foot seas. Once in trouble I made the decision to push it untill it broke or made it across. My buddy boat was there with me in case I had to be towed or even abandon my boat to save my tail. It took over 10 hours to cross but we made it....Anyway enough about the trip (adventure). My engine wouldn't push me more than about 7 mph full throttle. I could cut back to idle for a few minutes then I could get full throttle out of her for a few moments at which time she would just power back again. I actually crossed the gulfstream at 5mph and burned 50 gallons of fuel doing so. The reason I know is I have a 50 gal tank and ran out 1 mile from Ft Lauderdale. My buddy boat went and fetched me a 5 gallon can of gas and once fueled up she ran fine for some time when the trouble began again.<br /><br />I don't think she was running hot but do suspect a faulty temp sensor may have been sending a signal to shut down the engine. Does this make any sense? Any other ideas? Hope I didn't do any damage to the engine, under any other circumstances I would never push a poorly running engine for 10 hours but I had no choice.<br /><br />Thanks for any advice.
