Hi,
My outboard gives a solid alarm at about 3300 RPM and drops to idle. I shut it off and it starts right back up. I can run again at around that RPM for a couple of minutes, then happens again. I haven't tried to run faster to try to avoid extra damage when it drops RPMs. I have posted this prob. on another forum and got some good feedback but the problem continues. Here is what I have done so far:
-New heat sensors on exhaust manifold
-New t-stats
- New HP & LP fuel filter
-Water pump has about 5 hours on it now
- Inspected most of the coolant lines
- Checked fuel pump pressure
These things did not help the problem. So I bought the HDS kit. I found that the engine temp was fine while running fast and slow speeds. But one thing I noticed on the screen is that my High pressure oil sensor was OFF and my low pressure oil sensor was ON. Should they both be on or off? I will try to post a pic of the read out while the engine was running at idle.
Someone suggested checking my crank shaft end play. Not sure how to do that. Any help would be greatly appreciated.
Than you for your time.
