the biggest thing is that you don't want a big variation between them.
5 ether way is fine but if you had 1 cylinder showing 107 lets say, that could indicate an issue.

I had my outboard serviced and on the report it says

2) 120
3) 125
4) 120

Cheers :) ]]> Wed, 26 Feb 2020 19:33:18 +0000 https://www.fishing.net.nz/forum/forum_posts.asp?TID=133006&PID=1774042&title=good-compression#1774042 https://www.fishing.net.nz/forum/forum_posts.asp?TID=133006&PID=1774038&title=good-compression#1774038 Author: smudge

1st make sure measure correct.
2005 manual
" 1/ run out board till full operating temp reached, shut down
2/disconnect crank shaft position sensor
3/move throttle linkage to WoT
4/ turn over on starter measure max pressure on each cylinder

Sry cant find pressure specs.. I would think around the 115lbs ???.. Thu what looking for is difference between cylinders. Anything over 10/12% indicates something wrong.

Also a engine that has a build up of carbon in the chamber has a higher compression, assuming that the rings etc in good condition .. hence why looking at the variation.

G’day

I was wondering what you guys would consider decent compression for a 1998 Johnson 90hp ?

Cheers
