  • New 150ss Suzuki 4 Stroke

    While in break-in period with only 6 hours the motor smoked so badly on start up I could hardly see it. I called dealer and he said not to worry about it because it has 6 year warranty. I told him I was very concerned about it doing that. I checked oil and it is at 3/4 on the dip stick. Waiting til 20 hours to take it in for first scheduled maintenance.
    Anyone else ever have that happen?

    I've just got the regular 150 and only have 4 hrs on it. No smoke and oil is the same as day 1.

      I think its a bit early to be concerned - while perhaps unusual, your experience is evidence of why there is a break-in. You may want to run it harder for frequent short periods (say 5-10 min at WOT) to help seat the rings - at least that is what I would do. And you don't have to wait 'till 20 hours for a service - for my F150 Yamaha I changed the oil and filter myself at 10 hrs - quite easy to do and made me sleep better.

        When the motor is not being used, how is it stored? Tilted up, or dropped down so it is vertical? Ideally it should be dropped down so it is vertical, will minimise issues such as you have reported.

        That said, unless it was overfilled, you shouldnt be getting so much smoke. A small puff is not unusual, though.

        Has it settled down now, or still smoking very noticeably??

          '''''''' I would be a bit concerned if I just bought a new motor and it was blowing out a lot of smoke at start up. Unless it is way over full because the dip stick is not at the right height, or as moonlighter said, something is not right, drain the oil and make sure the right amount is in the engine and the right oil. Pull the plugs out and have a look and see if it is one cyl or all.

            Alright. It has been quite awhile since my last post about my 150SS smoking at start up and it now has around 250 hours on it. It will not smoke on initial start up while backing off the trailer but only after I'm on the lake fishing. It smoked a week ago but the next 5 times out it did not smoke. Yesterday however it smoked quite noticeably two different times. The dealer says don't worry, it's under warranty. Suzuki says it is not excessive oil consumption because the oil level only goes down an inch on the dip stick per hundred hours run. The dealer ran a leak test with no problem found. Any input on this? Thanks

              I have a 2009 DF 90A, it has never smoked nor have I ever had to add oil between oil changes. When moored the engine is tilted up out of the water. The grandchildren run it hard pulling skiers and tubes and we also troll with it.

                Did the dealer check and if required adjust the valve clearances at the 200hr service?

                Pretty sure that is a required action at 200hrs and it may have something to do with the smoking. If its not done Suzuki may not play ball with subsequent related warranty cliams.

                  Don't leave it trimmed fully in when off. Oil _will_ be at back of pistons etc during normal running. If you trim full in then shut off, the oil trying to drip back into the case drips into cylinders and pools up behind pistons. Over time this seeps past rings settling into the combustion side. If tiled just a hair out, this same oil landing on the cylinder walls trickles towards the crank and drains nicely into the case.. If you don't believe oil will seep past the rings, try starting a car motor when the car has been on its roof for a few hours, enough oil in that case goes to the wrong side to hydro lock the motor.. In a boat motor the cylinders run front to back not up/down so they need to be allowed to drain towards the crank, not towards the head.....
