Re: PLEASE HELP ....1999 Johnson 90HP

I went over to my mechanic and explained my issue ...
He thinks my issue from the start has been a bad fuel pump , i was having this issue a few weeks ago but the No Oil Light was coming on ...

Which would probably happen if it was starving for gas correct ?????

I removed the oil injection and this came again ...
The wierd part is it does not do it while running 3500-5000rpms , but when going slow (no wake) it does .... No Vacumm ?

Im going to pull the fuel pump off and have my local mechanic rebuild it and take a look ?

How would i check the tank vent ? Its on the side of the boat ....
I think its good but why not check it ....

Hope this fixes the problem.
As for the fluid, I don't know, never owned a motor that had it. I have one I've been working on, but have not had to even touch the TnT system.

if you didn't snag a manual yet..

I think you are throwing parts at it at this point, you might get lucky or spend a lot of lolly and fix nothing.

The fact it runs fine at higher rpm tells me its not fuel pump.
Methinks carbs.

Re: PLEASE HELP ....1999 Johnson 90HP

Am i correct or does the Fuel Pump work off of Vacumm ?

Gets good Vacumm at High RPM's but in a no wake area is when it acts up ..
When the Vacumm is low ....

If i pump the bulb it clears up and runs fine , if i dont pump it , it bucks like its running out of gas ....

Yes i ordered a Manual just awaiting its arrival ...
