First off thanks to all of you for all your posts! After doing much research on this site I was able to resurrect my Force.
Now for my problem for the second year in a row my fuel pump diaphragm has ripped after only 3 weekends. I have no clue what could be causing this problem. Any help would be appreciated. Details on the boat 1987 18' Bayliner Capri with a 125HP Force. The boat sat out of the water for about 5 years before I got it. I have rebuilt the carbs, replaced the spark plugs, rebuilt the fuel pump including replacement of the (3) check valves using Sierra 18-7806-1 Marine Fuel Pump Kit. All new fuel lines including primer bulb. New inline fuel filter. Drained all old gas and flushed tank. Replaced the impeller and lower unit seals. Ran 3 cans of Sea Foam. 17 Pitch prop.
The boat runs about 4500 rpm at WOT that's according to the original tach. Before the diaphragm ripped the boat ran like a champ was able to pull a skier with 5 adults in the boat so no complaints there. Any help is appreciated. Thanks in advance.
