Have you checked the anti-syphon valve on the fuel tank. Does the primer bulb want to go flat. ???

Seeing it's a 2000 model built by OMC, you may just have a bad system check gauge. They did have probs. See if you can find a loaner just to plug in and try. I still keep one in my tool box just for that purpose.

okay---so thats the complete rpm gauge unit---so maybe its a fluke it just happened after i changed fuel filter

Find the tan wire that goes to the vacuum switch on the port side of the mtr and disconnect that and run it. It could also be a bad switch. The switch is plumbed into the fuel lines.

also ive read up on the check engine light and buzzer its caused by a vaccum---or restriction correct----funny after i changed this filter to a seasense unversial on this started happening --could this filter be to small of inlet and outlet to let the fuel go through like it should----it had plastic one on it--this type on there now is metal with glass see through with removable filter-----also as i was removing the filter the small line that hooks to the fuel line in a tee going into the pump came loose i put it back together it goes into a small valve like with two wires coming out of it hooked up to a plug--everythings hooked back up but could i have done something else not knowing ---taking guesses here but i dont see unit just going bad without any warning exspecially after ive done what i hae done which seems to be the root of the cause according to what iam reading--if i had not changed filter and this happened --yes i could think it might be a bad unit--possibilites?

Re: 2000 johnson225 ho check engine light and buzzer coming on

If it were me, I would remove the new filter completely for testing purposes. Simple enough.
