I have two 1993 Force 120's on a Trophy Walkaround. The port motor will began to lose power, rpm's steadily dropping until it quits. I checked the fuel connections and re-primed using the priming bulb. It starts great and gets going...up to 4000 rpm's...in a minute the problem repeats itself...I re-prime, she starts, runs and quits. I must have been losing prime...the bulb was flat each time I re-primed. So far I have replaced the fuel lines from the fuel water sep to the fuel pump and to the solenoid...I have new fuel water sep cartridges. There are other fuel lines to replace, and the primer solenoid too....what can you suggest? I think I should go ahead and take apart the fuel pump. I have a manual, but it only has directions for the two-stage pump....this one is square shaped. Thanks.

Re: jbeale

All pumps are basically the same just make sure you put it back together right.Do both pumps with new diaphrams.New squeezie bulbs??
Do you have 2 pick-up tubes?It sounds like one of them is plugging up.
I'd change the both hoses from the tank and the primer bulbs.
Ethanol is really screwing up a lot of stuff.J

I will get the diaphrams? When I read about the dual stage fuel pumps there was a warning to make sure and get screens which arn't included in kits....I'll ask our local Mercury Parts and Service about that too. This is obviously not dual stage...are you saying that all I need is diaphrams? Is there a kit to get? I already installed new "squeezie" (primer) bulbs and fuel lines from the tank, fuel water seperator, pump,and...well, I can't identify the last connection near the "primer relay"(?)...what do you mean by "pick-up tubes?" My friend said vacuum tubes...that the same? Where I last connected the new fuel lines must be directly below the primer relay and vacuum lines...right? I have been using a Mercury brand concentrated mix of fuel stabilizer and enhancement.....the fuel looks fine; I haven't seen anything to indicate that it's bad, but it has been about 70 gallons in the tank since October. By-the-way....I appreciate your help, and I'm glad to have found this website.
