Hi there,
I searched the iBoats forum for my particular problem and could not find one that involved something that I noticed with my alarm. The outboard is a 1999 115hp Johnson 4stroke with external oil tank.
I have only run the outboard with muffs when observing this problem. The problem is a fuel restriction alarm (1second on 1 second off repeat), but this only happens after 5-6 minutes at idle speed, I have left the alarm on for 5+ seconds and then put the revs on (both in gear and out of gear) and the alarm speeds to about half second on half off for about 2 seconds then it just stops, meanwhile there is no noticeable change in revs, smell or heat on the outboard. I have done the following to try and single out the problem; used premixed fuel at 100:1 ratio to see if the alarm stops, it changed nothing except a much smoother idle. I have also replaced the fuel primer bulb because I noticed that there was fuel sometimes coming out one side. I have also rang the boat repair shop that I usually use for checkups and such but they have been to busy to be able to help and suggested that the fuel pump is probably worn out and does not take in enough fuel at low revs (something along those lines.)
In 4 days we are going camping for 8 days to do some serious boating, so I am looking for some help or second thoughts on whether the engine could be run as it is or not. The reason I ask this is because exactly one year ago the outboard had the same problem but the alarm would go off after about 10 minutes at idle or only on very rare occasions, so I assume it has gotten somewhat worse. Should I drive to a further away boat shop tomorrow to get this fixed or is it something that can wait until afterwards.
I'd appreciate any help/thoughts!
Cheers and happy new years.
