If you show oil on the dip stick, you are most likely good.You would need to be almost completely out of oil so the oil pickup in the pan sucks air for the pressure to drop. Adding more oil will not affect the pressure.

I thought it would clean very well and I thought that would be better. Bought two of them at the same time. I believe I had to remove that filter as it did not flow enough fuel. I don't remember the required filter size, 10-20 micron??? I should remember since it tripped me up and I had to throw away two new filters. I checked my book and I did not keep notes, sorry. You might check and see what you installed for a filter. This is the screw on filter mounted in the engine compartment.

I bought the same one that was installed before, not sure about the micron. You think this one is ok?

Her's the thread on the GT40

Hi Community

My ProBoss GT40 on a ski nautique 1996 has a special problem. If i give full throttle it stucks at 2800RPM and falls down to 2300RPM this process repeats then every few seconds. If i stay under the 2800 everything works fine. I dont know what the problem is, last year everything was fine with it. but this season is really bad to start :/ maybe someone could help me out? 😕

I did check the forum and google but can’t find this specific problem. I also checked the manual but cant find any solution for this failure. Is there any possibility that there is a fault by the computer snd i have to reset the computer? Is this even possible to reset the computer?

Please help me out i dont know what i can do to make this engine work again.

Sry for my bad english 😅
