Hey
Just purchased my first boat and am looking to get the 89 Johnson 70hp 2 stroke serviced. Called a reputable place for a quote ans was told minimum $450 - $550.............
Can anyone recommend somewhere I can take it to in the Perth area, North of river, where the cost is a little more reasonable?
Outboard just need a service and tuneup, plugs are fouling and is running a bit rich thus stalling when hot and going from neutral into forward.
Cheers!
so, where do you live?
cheers

Mate the motor is not worth that much.
how about having a crack at it your self! order some parts get some oil and plugs a service manuel and let us help you out with some details. Hell it's only a 3 cyl lawnmower, and an old one at that.
A marriage licence should be like your fishing licence!
Expires every year and you get a 3 day pass when you go interstate.
I called another joint and was quoted $350 for service, but was warned it could well be over $500 if the carbies need any work...... Told the bloke bout the fouling of plugs and stalling and he seemed to think a leaking carbie.
Anyhow there is no way in hell Im spending $500+ on servicing the motor, I think considering the age of it and price i paid for the boat it makes it a an unrealisitc thing to do.
I am pretty mechanically minded and am more than willing to give servicing it a crack. I have receipts from the previous owner showing servicing done at a dealership, last july the carbies were cleaned and adjusted and from what he has told me the boat has virtually sat in his garage for the past yr with little to no use. So I am doubting the leaking carbie theory.
I have managed to find a workshop manual, its a pretty broad one covering many models though so its a little difficult to follow.
The plugs in the boat are oily and black, probably not producing a decent spark either. The motor is definately running a bit rich and I think the fouled plugs are contributing to the stalling when hot. The VRO was removed last service and thus the idle etc was rejigged, I dont think the idle was set properly under load.
Anyhow I am mixing the oil in fuel at 50:1 and am going to replace the spark plugs tommorow and see how she runs. From there I think i might have a fiddle with the idle speed screw and see what effect that has. The motor runs fine, starts first turn, idles fine when cold and performs ok, just seems to be a bit rich and intermitently stalls when going into gear and hot.
Any other reasons for stalling when hot?
I prolly should have started a new thread specifically on this topic, sorry
Cheers for all replies so far, really appreciate it!
I cant recomend enough coughing up the cash to the the genuine paper manual for that motor.
If the johno manuals are anything like the merc ones, it will all be there in detail.
most of the stuff you need to do isn't complicate or expensive in parts, just dirty and time consuming.
When I first started looking at this stuff I could not bleieve how simple and straight out crude some of these motors are.......if you can manage typical motor repair tasks on a car, it should be a dodde.....you just need to be fussy.
cheers
Its the details, those little details, that make the difference.
best reason for a carby to leak , no fuel so seals dry up and go brittle and leak like seives . sucking in air may cause the rough running too
$ 550 was the price that I was also quoted for a yearly service.
Can someone let me know what the correct plugs and the gap is for this motor?
Thanks for your assistance.
Graham.
My workshop manual says Champion plugs QL77JC4 or L77JC4 gapped to 0.040
