I just recently purchased this boat and motor. It has 130 hours. The guy I had bought it from said he rarely used it, maybe a few times a year. He did say that he had fuel issues in the past for letting it sit so long without use or fuel treatment. I kinda figured it would need some type of fuel system cleaning. When buying I started it (on muffs) and ran it through the gears with absolutely no problems.(Did not rev above 2k).
Got home and put it in the water. Started and ran great for a short period at around 5800 rpm. Within a few minutes the idle dropped to around 4800 rpm and would stay there until I would stop and let it idle for a a short period.(1 minute or so) Then I would get it full speed again and within about 30 seconds it would drop again. It would never cut out or die, just drop rpm. The drop was kinda be gradual at first the drop off quick. within about 5 seconds.
It gets worse..About this time the oil light comes on few a few seconds then went off. I headed home. Noticed a oil slick in the water at the dock. I get home and find the oil is at the bottom of the dipstick. I can see some light oil residue around on the inside of the lower housing. The air intake seems to be somewhat wet but I really can't tell.
On to the shop((certified Suzuki dealer). Request a fuel system cleaning and to figure out where the oil went. Two weeks later I get a call saying that the oil light had come on and and the mechanic is not sure that after doing a $1000+ dollar fuel system cleaning there isn't other problems. I asked him how the compression checked he said he never did one. We decided I would choose my course of action dependent on the compression check. Calls me the next day and says that compression is good but there is burnt oil on two of the plugs and he was not going to do anymore work on it. I asked him what I should do and he said that's up to you but I'm not doing it. I asked him what would cause that and he said it could be carbon on the valves and felt the engine was "wore out". I asked him about doing a decarb and he said I could try that if I wanted. He said it would be easier to put a new motor on it then tear it down and fix. But he was done and I owe him a couple hours labor.
I'm lost on what to do other than a ring free cleaning.
