Re: Installing an Electric Fuel Pump?
I also have a sport jet 90. This last winter I stored the boat outside with a boat cover. I winterized it properly except for one thing, removing the hull plugs. Needless to say when I picked it up the engine compartment was full of water. I live in Wisconsin so I'm sure it was frozen.
I got it home and pulled the plugs. The top two came out fine but the bottom third plug came out and water followed. So some how water got into the motor. I manually turned over the motor and pumped out all the remaining water. I put oil in the pistons and in the carb throat. I check the compression and its good.
But it looks like I am having a fuel problem. The mechanical fuel pump isn't pulling much fuel. I connected a clear line to a cup of gas and it barely sucks up the gas. I pulled the fuel pump apart and it seemed ok. The diaphragm didn't have an holes in it and everything seemed to be clean.
So I am wondering if the motor isn't producing a strong enough vacuum to pull the gas in because of freeze damage or is the pump just bad. I dont know enough about each one to tell. How can I tell if the motor is damaged internally without pulling it apart? Should I try to start it with a little gas in the piston? My next thought was to put an electric fuel pump but after reading this thread I guess that is out of the question. Any help out there would be greatly appreciated!
