115 merc 4 stroke fuel pump

[brigeton]

As stated I have a 115 Merc 4 stroke I bought last year. Before that the boat had a 90 etec. I have a spin on fuel filter and need to change it.There is no squeeze bulb in the fuel line. If I just turn the key on will the pump fill the new filter and how long will it take? If I try to start it and the filter/fuel line isn't full will it cause any alarms? The dealer I bought the motor from is out of business now cause the owner died last winter.

Ya fuel pump should fill it , turn key and you should be able to hear it start then when it stops you should be good to go

There is an inline fuel filter that should be changed as well. I changed mine a couple times, never an issue with starting after.

Are you talking about a water separating filter. If so it is good to fill the filter with gas before spinning it on.

Thanks for the replies. I really didn't want to fill it with gas first because any spilled will go into the bilge. I guess I can put it in a plastic bag then screw it on.

Never had any spill. No different than taking it off. Put a small plastic container under it.
