Hello All,
I am recently a "new" boat owner. I've been reviewing the forums and have only recently joined up. I appreciate any feedback and advice you all may give and hopefully can learn some to help give back some day. So my sincere thanks in advance. I hope the post is not to long, just figured id throw all the info i had.
Here is my story:
I picked up a nice 1988 olympic 17' with two outboards, an early 70's Merc 1000ss and a 1989 Johnson 60 hp. Ive chosen to focus my attention on getting the Johnson up and running and so far it seems ok. She is a salt water motor that is showing the signs for sure. Ive got it all hooked up, built a deep running test tank and stand and trying to get it tuned properly so my kids and I can have a safe/reliable running outboard for this summer's boating season. Im familiar with two stokes(dirt bikes and the like) but not sure just how much applies to outboards. Im a decent mechanic and try and take care as i go, without back yarding it too much. Ive found a good shop manual resource online iv been following but have come up a little short on trouble shooting. I have been hesitant to run the motor at high speed even on warm up lever.
The Gist:
Starts and "runs" in the tank- haven't put it on the boat yet as i wanted to work out any and all bugs in the tank as much as I can. Have not run it under load.(though it runs it does NOT run as well as Id like).
Will prime with electric primer but will only run with the primer level in the manual position.
Smokes rather excessively at times. White/bluish smoke with black oily discharge rising into tank. Seams to be rich but as i don't know outboards and im hesitant to make assumptions.
Small tube from bottom of powerhead cylinder, on carb side, at bottom of spark arrester/silencer, periodically spits out grey(light at first now dark) gunk that smells like fuel, leaving a think residue on the inside at the bottom carb.
Excessive fuel collecting at carb air intake side(while running at idle and low speed) leaking out into intake side of throat. there seems to be small puddles collecting at the mouth of each carb. started of as clear fuel/mix but now has turned cloudy white.
Revs up(seemingly) excessively on warm up level and drastically, it goes from rough low speed idle to high speed( again im hesitant to let it but i know two strokes love their powerband).
plugs appear ok- black/bown electrodes, more to the black side(again maybe rich?) however the bottom cylinder does appear cleaner on the ceramic(maybe water indicated?, I REALLY HOPE NOT)
What Ive discovered and done, hopefully nothing too stupid:
Shows signs of "work" being done-wires cut and spliced, some bolts/nuts that don't appear oem. I haven't touched the wiring much except to clean contact points showing signs of excessive corrosion and when the starter was replaced.
Opened solenoid and de-carbonized-Drilled out rivets and opened up to find it well used. removed carbon build up, sanded contacts with 600 grit, reassembled, riveted back together with hand rivet gun. works much better under load.
Turns over well- I had to replace starter due to previous person maybe overheating the starter so the had winding's let go. ran a draw test to determine and pulled apart, found broken windings and replaced.
Compression is 100 +/- 3lbs per cylinder(good/bad?)
Spark is good- used an old Johnson spark tester as well as grounding plugs and exterior test. New Plugs.
Water is streaming(peeing) from indicator port and through exhaust on the stem and out of propeller(also briefly tested at Idle on Muffs outside the tank). So far the heat seams consistant through out the block but not sure of opperational temp?
takes fuel well- have an original in the box brand new OMC tank, No rust or corrosion present inside or out. new fuel lines, connectors and bulb. fuel filter is unimpeded.
Removed carbs and removed build up, cleaned jetting and any Shellac i found. some green build up in bowl but not much.
Reeds appear in decent shape- All there, no gaps or cracking visible, gaskets also appear in decent shape
Running 50-1 gas/oil mix(johnson brand oil, new fuel 92 octane) as the VRO has been plugged by previous persons. most likely will try out VRO at later date but want to focus my attention on the power head and getting it running first as ive read the vro can be touchy.
Gentleman if you have any ideas or direction its much appreciated. Its my first personal boat and want to get it out on the bay so my family and i can share it. Thanks so much for checking out my post and getting back with your ideas.
