Re: Excessive oil consumption 115 HP Mercury
Thanks The_Kid that helped a ton. Well here is the update spent the whole day doing the link and sync, timing adjustment, idle setting, cam and follower, oil pump you name it I did it. All thats left now is to adjust the top 2 carbs air/fuel mix tomorrow when I hit the water.
Pros of doing this procedure, I realized things go way out of whak over the years. The timing for idle speed was about 8? out and the WOT timing was 18? out, she was running at 40?BTDC at WOT. I am expecting better performance from the old girl tomorrow. Everything went well, except for the air /fuel mix which needs to be done in forward gear at idle. When I was done I hooked up the water hose and decided not to give her any throttle on the start. In the past I had to give her full throttle from a cold start, this time first crank she took and died, second crank fired up and ran smooth as silk. I was real impressed.
Cons of doing this, you have to keep your wits about you at all times, know your parts and where they are located. The last con is something I will need to do more research on, my throttle cable is set correctly with just enough preload. At idle the cam and follower have the correct gap, the carbs are all closed but for some reason I run out of throttle travel when accelerating. Its not much but when I bottom out on the cable retainer I have about 1 or 2mm of carb plate movement still to go. The only way I can see this improving is if I reduce the cam and follower gap, but the spec is only 0.125mm to .57mm and I am at 0.3mm at the moment. I am not sure how much this will effct performance as I mentioned the carb plates are only about 1 or 2mm from perfectly horizontal.
I will post again after tomorrows river run, interrested to see my oil consumption after the oil pump adjustment.
