I have an 1995 150 HP Johnson Motor on a 17 ft Sea Pro Model # J150ELEOM. When I first bought the boat used, the boat was having a fuel issue that lead from one thing to another. The first issue was that once the motor reached RPM speed's of 5500 it would run for just a few minutes and then die off unless it was kicked back down to 4500-4800 RPM's and then ran fine. At the time the carberators were cleaned and the screen that is at the bottom of the pick up tube that goes into the gas tank was removed from the tube with a wire that I pushed down the pick up tube line to remove it. Also I replaced the fuel wator seperator and also installed all brand new fuel lines leading from the gas tank to the engine as well. After the gas lines were replaced, changed the spark plugs out to the OEM Champion brand spark plugs, and removed the screen that is at the bottom of the pick up line that goes into the gas tank, the engine started running better at 5200 RPMS just not at 5500. For the next couple trips it worked fine until the engine started to have an even worse fuel issues. NOTE: THIS BOAT IS BEING OPERATED AT A 2 STROKE 50:1 RATIO EVEN THOUGH IT DOES HAVE A VRO, BUT THE VRO IS NOT HOOKED UP AS FAR AS THE OIL PORTION.
long story short to this date the all Fuel lines replaced from tank to engine, fuel water seperator replaced, VRO fuel pump replaced with a Non-Oiling Pump, the Red Plug thing that is on the engine for the Choke was leaking so that was replaced. Carberators not cleaned out but the mechanic stated that they were clean when they inspected the drain plug from the bowls, and also the fuel lines dont have any air leaks.
So Right now the engine at full throttle will run perfect for 2-3 minutes and then has to be shut off to cool down cause of over heating issue. If the engine is ran at 3/4 Throttle it will run great with no rpoblems of over heating. Any advise would be greatly appreciated.
