suzuki 85 hp problem

IWyk, with all due respect to all, Suzuki motors is the most difficult motors to sort, especially the older 2 stroke motors. They always test right in the shop and aware of the torque/load issue. I have read all your replies on this matter and yes, i could agree with your mitigation options. The main concern now is cold vs running temp! I will look back in faults found to similar problems that have been sorted.One thing I would like to ask for you Neville, is when your motor cut out, does it just die or does it give you the Suzuki"bla" sound and then dies.?
Neville,one thing you also need to consider (although you have stated that you have cleaned the carbs, method used unknown)this might well as be a fuel starvation, since no one has been fiddling with the timing.
The following procedure, jou have butterfly chokes and not solinoids, get the boat, realy slow in moving mostion and continue until you have sufficient rpm, trip the choke, don't let it vrek, continue with this procedure 5 or 6 time and it should be sorted.

Hi guys
Thanks for all the replies. I woke up this morning and that little itch in my throat had got me. MAN DOWN. So I did even look at the motor today. Maybe tomorrow but for now it's Medlemon and Acc 200.
When we discovered the problem we were on a dam. We eventually started the motor, engaged gear and crawled home. We did remove the cover and when my mate played with the butterflies we took of like a bomb. Also I think it made that typical Suzuki "bla" sound.

I need to agree here.
a possible air leak.
seems like its running lean.
cheap fix, but could be difficult to isolate

Morning,
So at the first opportunity I get into the garage and remove the cover. Here is the business end of the duck (photo).
So after opening the cover I stood back to get this pic. As I stood there I realised that all the clamps inside the cover on the fuel line and everywhere else have been replaced with tie backs. All except two clamps at the fuel filter. Well I will get that sorted but as only the boat dealer and my friend and I have worked in here since I bought it, I wonder where those clamps are now.
Anyway I wiped every part of the fuel line clean and dry. Got out the extra light and set to work on that fuel ball. It got hard and I kept it hard while looking for any telltale signs of moisture. I did not see any so I put paper towel around the pump and pressed the fuel ball hard again. The paper remained dry.
Tomorrow my friend who is far more clued up than me will run through the pro essential with me again. We will also check out all the other leads mentioned.
Thanks guys

ok went past Neville and checked his motor......
still looks good.
engine is clean.
we did discuss certain aspects that need to be done. doing this, to exclude that, bla bla etc.
his fuel is indeed being sucked back into the tank.
the primer bulb does not stay hard.
if you listen closely you can hear the hissing sound.
we know that this is something small only time will tell.
it must be noted:
motor was serviced by boat and caravan apex.
it was taken for a test run and all seemed fine "after service"
just before Neville was about to leave for holiday, he took it out for another test.
this is when the problem started.
Neville took the boat back to camping in apex but they could not rectify the fault. so Neville cancelled his fishing trip
the boat was again taken out with a technician from boat and caravan apex.
this guy seems not to be on the ball with regards to the problem at hand.
So when Neville gets time, he will take the boat out and do tests systematically to exclude them.
so we will be waiting for feedback from him.

Too many boat shops and mechanics who don't have a clue what they are doing. All well and fine to service an outboard and charge a fortune doing so, but very few who can troubleshoot and fix issues when they arise.
Let's hope Neville gets it sorted and keeps us updated. it is always good to learn from these incidence for future reference.
Nice of you to go past there Willem.
Ps. Is the primer bulb not suppose to be one way only?

well its not.
just take note, Neville's fuel line connection at the motor is the very old type.
we can speculate on what the problem is. but until the basics have been eliminated we'll have to wait.
yip, the techie was a new era technician!
sad thing is, the service was about 3k.
ag wel. kom ons wag en sien.

I own a Suzuki 85 that I purchased new in 1986. It was originally used for waterskiing on a speedboat and later carried over to my cabin boat. It is still in regular use and I think this is an excellent motor. I have owned various other motors over the years and this is still my favourite. I once experienced a similar problem with this motor, starting fine when cold and as soon as it got warmer and you pushed it into gear it would cut out. The problem turned out to be the following:
The prop picked up some braid and this damaged the seal at the bottom of the gearbox allowing some oil to leak out dropping the oil level in the gearbox. The main shaft coming from the power head to the gearbox runs in a bearing and this bearing was now running dry. With the bearing being tight the motor would die when pushed in gear. Hope this makes sense, but it is the explanation given to me by the mechanic. Only problem I ever had with this motor and probably caused by braid in the water and not a weakness on the motor.
