I have a smooth running ‘94 Evinrude 8Hp, but have been on the lookout for a spare prop.
I came across a farmer who had tossed this ‘91 Johnson 8HP in the scrap pile. Said he lost the water pump & overheated. Sat in his shop for a couple years, his kid went to look at it & said it was seized, so it was being thrown out.
Seized or not, it was worth what he settled for, a few beer tokens, or the cost of a used prop.
Took it home, sprayed some fogging oil in the spark plug holes, & it pulled over easily. Turned out he had it in reverse gear when he showed me it was seized...of course it wouldn’t turn over.
I tested for spark, no joy. However, the kill switch looked broken, so I put the multi-meter on, sure enough, no circuit. Wobbled the kill switch around & got continuity & it will jump blue spark across 1/2” gap on my home made tester.
Ignition seems good, so I decided to go deeper. Compression seemed low, (60psi both jugs), but when I tested my 4 stroke pressure washer, it also read 60! And that engine starts runs fine. WTH... two bad compression gauges in a row?
I pulled the head, gasket looked OK, but I don’t know the significance of those bubbles, which are on both sides.Nor the grungy stuff surrounding the thermostat, it seems metallic.
It appears there was some sort of ring surrounding the thermostat, but it now corroded.
It definitely got hot, see the discolouration on the head paint.
The head is definitely warped somewhat, I can just slide an .005” feeler under a straightedge, near the Center of the head.
This kicker shares many parts with my ‘94, both are Belgium made. I don’t like to break it up if it’s a good motor.
Thoughts on repair?
At minimum, I will need a new kill switch, & gaskets for head & inner/outerexhaust cover, & probably a carb clean.
