    97 Johnson 90hp Bogs after sinking

    Powerpack was the culprit replaced it and runs like a dream again.

    97 Johnson 90hp Bogs after sinking

    Confirmed when motor has spark the orange/red wire going from the powerpack to the optical sensor has almost 13v (10.5-12vdc) is the recommended range so a little out of spec. Powerpack ordered should be here in a few days Removed thermostats, they screw into a blind hole with no water flow...

    97 Johnson 90hp Bogs after sinking

    Alright will remove thermostats next time engine is running and check for adequate or equal flow from both ports. What would the proper way to bypass the temp sensors temporarily to deactivate SLOW be? Can't find a video or forum on this engine on how to bypass but I've seen other Johnsons that...

    97 Johnson 90hp Bogs after sinking

    Since it sank the telltale has been abnormally strong and one head is warmer than the other im concerned there may be a clog in the head somewhere causing the higher backpressure. Do you think this is possible? Do you know of a way to clear out the water passages in the head? Can I blow...

    97 Johnson 90hp Bogs after sinking

    Ok update, We went out to troubleshoot and discovered a yellow/red wire on one of the powerpack 4pin connectors had come unpinned and I could see the weather seal so it wasn't seated enough to make contact! Thinking surely this was the source of all the problems I reseated it and put the motor...

    97 Johnson 90hp Bogs after sinking

    Ah I see the 2 banks are slightly offset leftside being slightly higher So is it 1/3 .............2/4 or 1/2 3/4? This is so frustrating we have 0 spark now after the last time it died, moved the bad wire, replaced the coil pack no change. It's like there's a main issue causing loss of spark...

    97 Johnson 90hp Bogs after sinking

    Ok got out to the boat today to do some troubleshooting on the water, planned on testing the temp sensors and coils and also got some new coils to install if they were bad. This issue only arises under load so I popped the engine cover whial my buddy drove and as soon as I started pressing and...

    97 Johnson 90hp Bogs after sinking

    Absolutly! Not something we are doing regularly just something I noticed during troubleshooting and found odd. I was thinking if carbs were clogged it wouldn't high idle or rev in neutral but it does so I ruled out carbs for a bit and started leaning towards coils. I will search up testing...

    97 Johnson 90hp Bogs after sinking

    Ok now this is interesting! So since the sinking the tell tail has been unusually strong, like it used to shoot say a foot with adequate pressure and now it shoots like 3ft and if you Rev the engine it shoots almost 10ft like a pressure washer with a zero tip. Was thinking it was a sign of a...

    97 Johnson 90hp Bogs after sinking

    Visually inspected oil tank after sinking, no signs of moisture and oil bulb was still firm. Should we clear that system somehow? After not finding water in the oil tank I assumed the system being under pressure kept any water ingress into that system. I should add it was the rear of the boat...

    97 Johnson 90hp Bogs after sinking

    Hello all, New here hoping to find some help. My buddy has a 97 Johnson 90hp 2 stroke outboard (J90eleuc) that recently sunk in fresh water (bad storm & bilge). Was submerged 12hrs tops. Now it won't go over 10% throttle without shaking and bogging. I'll give everyone the steps as they occurred...
