Have Boat Questions? Ask a Boat Repair Expert.
Hello, my name is***** will be assisting you.
Do you have SmartCraft gauges, if so what is the alarm code or the text that it is displaying?
Deos the alarm say Lift ump time out?
Did your tech replace both floats?
Is it always the same engine with the problem?
The alarm will reset after every key up. Is there a primer bulb in your fuel line?
Some riggers do not understand that the engine does not require a primer bulb. That is why I have to ask.
Most of the time when this happens it is the float that causes it. It can spin up the shaft that it is on and not allow the lift pump to turn on. A code of lift pump time out, would mean that it ran for longer than 180 seconds. This can be due to either sucking air in the system or a restricted fuel line. A clogged inlet filter would do the same thing. Make sure that all of your fuel hoses are tight, if you have a filter in the boat, make sure that it only has one gasket on it. You may also want to check the pick up in the fuel tank to make sure that you do not have an issue there.
If you see the lift pump alarm again, try to slow the engine down some. If it is the float, that will allow it to drop down and then fill the FSM with fuel again. The you can take off again. If the issue is more at idle, it may not be the pump, but a hose inside the FSM that is broken. That doe not normally happen on the 10 model, but it could.
If it does sound, shut the engine down, then turn the key on, engine off, for 10 seconds. Do this 5 or more times. That will reprime the system and you can get going again.
Personally, I dont think that I would have replaced the pump. Unless I had checked all possible items including the tank first. Float yes.
Yes, that is when the pump ran too long.
Have your guy inspect the pick u in the fuel tank and the filter in the boat if you have one. You should be ok out there since the parts are new. If it does happen to you again, it is going to be an issue in the boat and not on the engine. Could be something as simple as a loose hose clamp allowing the syustem to draw in air.
