Over the last few trips I have noticed I am using a little more fuel then usual. Last trip out I had a noticeable reduction in power. My port motor was running at maybe 25-50% less power. On plane you can even see a difference in the amount of water coming off the prop. Also sounded like it was missing a little bit.
Got it home and first thing checked the spark plugs. Bought boat in march with 500 hours and no idea when the plugs were done last. pulled the plugs and 5 had some carbon build up and 1 was wet with oil I think. Start calling stores and cant find the NGK. The Delco's look different so I ended up buying the autolite plugs. I had a charter today so needed it to work at least for a day until I can get the NGK's. Start up the motor after replacing plugs and where the hose for the pee line hooks to the outlet on the block was disconnected. This is very close to the intake. Then I check the oil and its VERY milky. I think it was from the water spraying by the intake and getting sucked in. Did 4 oil changes to clean it out and ran it on a trip today. After the trip the oil is nice and clean so it must have been that hose. But still sounds like its missing and loss of power
Just did a compression test and it ranged from 175-182psi. Is that good?
If that good then mechanically the motor is likely ok right? I thinking the water damaged a sensor or something. I know I once sucked a bunch of water into a landrover and damaged the mass airflow sensor.
Another thing to note. When at idle when I first started it this morning after a little while the red light on the key came on with a alarm. Was steady on. Then when warming up the motors for the compression test it came on again. I just restart and light goes away.
Also a note. When I did the compression test I did not disconnect the fuel pump and give it full throttle like the directions state.
Any thoughts? Because the light came on can I get it scanned and then can tell me what it is or does the light have to be on when hooked to the scanner.
