I have a 1995 150 looper. I was runninig yesterday at 4200 rps. Engine temp was OK @160; Water pressure ~ 25 psi. I use VRO fuel pump replaced with latest version two years ago and I just replaced the plugs. (Champion - correct plug)
Was coming back in after about a 60 mile trip and one engine went from 4200 RPM and dropped rapidly. I shut her down immediately. Tried to restart and nothing. Im thinking siezed? Check the oil tank 1/2 full. I had disconnected the level switch several years ago as it falses all the time.
I pulled off the engine cover and felt the heads on the flat spot and they were equally hot. A two second touch was pushing it but you could hold your finger on them.
The engine alarms are all functional and I'm very aware of them. Engine did not go into SLOW - it just slowly lost power and quit.
I tried to start it again and it fired but you could tell it wasn't running "right" - but no bad noises.
After running it 15 miles back in when I get to the dock I notice a definite tapping sound - its still running poorly- stalling at idle and not up to power.
So I check the compression with warm engines and throttle wide open. Per my manual
port-stbd - from rear
70-105
78-102
100-102
Reading the plugs -
dry & black - lt brown with a sheen
dry & black - lt brown with a sheen
lt brown with a sheen - lt brown with a sheen
Accurate examples of my plugs can be found:

Sorry for the looooong post but I wanted to provide as much info as possible.
So with the above information - where do I start??? - Besides here
Thank you all for your much needed assistance!
