Boat has been running well and it was time to do an oil and fuel filter change (94 Hrs.) and a lower unit oil change (194 Hrs.). Did the engine work yesterday without a hitch and since Dan was doing both of his today I mooched his trailer after he completed his work so I would not have to drive to Vista to get mine. After fishing last Sunday I noticed 2 things; while setting the trolling lines I got a whiff of diesel exhaust above the transom which has NEVER happened, and in the slip at the end of the day I could hear a chirping noise coming from the top of the outdrive. I also saw more smoke at idle than I normally do and I normally only see that at start up. Well I thought it was a good idea to check it 6 hours ahead of schedule and my fears were correct; noticed a little sludge on the drive dipstick and when we pulled the drain plug it looked like a 1930s era soda squirter - 1-2 quarts of clear water followed by maybe 1 quart of slimey synthetic fluid. Since I didn't want to leave my boat out on Dan's trailer( I'm not sure he would have went for it either) all weekend we just refilled the case and buttoned her back up with new synthetic and put her back in the slip. The plus side is the chirping noise went away and there were no metal shavings on the drain plug; the bad side is a needed overhaul first of next week with probably complete bearings replacement. I hope the fish don't go wide open this weekend as it will be tough to stay off the water since I was able to go out only 1 of 3 days last weekend.
My smoke problem could be injector(s) related; everything else seems fine.
I guess it's just the cost of doing business !
P.S. - Dan's oil-to-water ratio was much better than mine!
