Re: 1997 Johnson 225 fuel restriction alarm.

I have the same motor (actually 2). Try a remote tank and see if you still have the same problem. I thought I had a restriction problem or a weak fuel pump so I troubled shot everything turned out to be low fuel and a bad gauge. BTW mine smoke pretty bad but when I ran on a remote tank the smoke almost all went away pointing to a problem with the something but I haven't found it yet.

One thing I am wondering is as someone stated do you really need 2 filters (spin on and the inline one)?

Depends on the filters.

In my case I'm running a 10 micron Racor with sight glass upstream of the 20 micron in-line on the motor. Running a 20 micron filter upstream of a 10 micron is fruitless.

Re: 1997 Johnson 225 fuel restriction alarm.

I have a couple of problems and I'm looking for some help:

Problem #1:
At full throttle I start to lose power and I have to squeeze the primer bulb which is soft and it will pick right back up to normal speed running fine. It will stay hard for a little while and go soft again sometimes minutes later during the same test run. Any thoughts?

Problem #2:
I start the engine and within 3-5 minutes At low idle speed in nuetral and also when in gear at low speeds under 5 mph I will get an alarm that goes off ( 1 beep per sec. )This will continue until I rev the engine in nuetral or go faster than 10 mph in gear and then it stops. If I'm in gear going at a trolling speed and it sounds I can move the trottle and go faster and the beeps get faster ( 2-3 per second ) and then it stops beeping. The alarm has never sounded at speeds 10 mph or faster... Once the alarm goes sounds I can speed up and the beeps get quicker as I speed up. If I slow back down they get slower. But once I reach a certain speed around 9 - 12 mph they alarm stops..... I can run the engine at a slow a trolling speed and it will sound and then I can go fast and it will go off until I slow back down then within a few minutes of going slow again it will sound. Any thoughts?

Engine is a 1985 Johnson 90 hp.

Questions: What would make this alarm sound? Heat, Oil, water pump?
