    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...

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

    Hi everyone. I have a new to me 1988 Evinrude 120 Model E120TLCCA. Had the boat out for the second time today running this motor.

    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

    Replaced the water pump. Now running with 30 psi and not over heating . Guess I'll try finding a better prop to help with performance. Thanks guys.

    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...

    I have the water pressure gauge tube connected to the small water tube going to the water control valve. Got that location on this forum. Thanks for your help.

    On Sunday I will post a picture of where I connected the water pressure line on the motor. Possibly wrong spot.

    I did on the 21 pitch and got 19% slip which is pretty poor.

    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.

    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.
