    1988 Evinrude loses spark to #4 after quick start drops out

    I just checked, still have original powerhead. By quick start I mean that it starts very easy, idles high until motor reaches about 95 degrees and then drops down to normal rpms. Then once warm, it starts very easy idles high for about 5 seconds and then drops down to normal. It is during...

    1985 looper 140 and a 1985 looper 120 powerhead exchange

    Hello all! I am currently running a 1985 140 20 inch shaft looper which has low compression on 1 cylinder (around 115 on 3 and 105 on the other). It still runs but is lacking at WOT. Just replaced the head gaskets and found moderate scuffing on the 105 psi cylinder. I don't if it's normal...

    1985 140 Johnson looper 20 degree temp difference between port and starboard

    WP gauge is connected to the adapter plate, Checked the gauge by shooting some compressed air in the line seems to be working correctly. Dropped the lower unit and connected the ear muffs to it and turned the water on. Plugged the water outlet with my finger some water was coming out along the...

    Also I don't believe there is any prop slip. The prop has a new hub and I marked the hub and prop and the marks are still aligned. Further the fuel pump has been rebuilt with OEM parts, and new power pack.

    1985 140 Johnson looper 20 degree temp difference between port and starboard

    I changed the impeller about 16 months ago. I am not running an aluminum prop. It is an older SS model prop # 387520 . I don't know but performance can be all prop related. I am thinking I should be running around 53 mph, 7 mph seems to be a lot to make up with a better prop.

    OMC Prop needs new Hub

    I have an older OMC SST prop 389924 (14.5 x 19) that spun the hub. I ordered and received hub 387157, the label on this hub reflects the hub is for an aluminum prop. Can it be used in my SST prop? If not, can anyone provide the correct hub part number? Thanks

    1985 140 Looper Exhaust Problem?

    This is a new to motor and first looper (miss my crossflow already). Just a quick question regarding the exhaust. I do not have any water or exhaust coming out of the two top exhaust ports while running the motor on muffs. I took the deflector off so I could put my finger in the holes. Could...
