Huuuuuuge help!! I've replaced almost everthing else on my smaller mercury (mariner) but this did the trick.

[@BetaGod]

same problem here on a 90hp 4 stroke carburator mariner.. tried new coils without any result! Suggest? i lost around 1k rpm and 10knots

I have a 1987 Johnson 150 V6 bro I can get to 40mph no problem but once I get there and continue to hammer it down, she boggs down and almost stalls unless I let up

i am having a similiar issue. don't know where to look anymore. My Mercury 90HP outboard 4 stroke at full throttle after 30 seconds starts jumping RPMs between 3k-4k and it just keeps shooting up and down non stop. Please help.

Subscribed immediately, thanks so much man! Exactly what was wrong with mine.

Have exact same issue, even have the same motor! Unfortunately I replaced x2 coils, wires, spark plugs, fuel filter and have fresh fuel…and still have same symptom.. when near WOT struggles to get onto high RPMs…messed with choke to see if it was needing fuel but made no difference…it would actually bog due to running rich with choke, I pulled carb off and didn’t notice anything clogged or out of ordinary. Went as far as pulling reeds off…they look fine I guess? Made out of metal…rubber seal looks good…not sure at this point?

I have a xr6 and will bog out during takeoff. I shut her off and she takes off fine but once gaining speed she starts bogging out again. Shop said it was fuel pump so I had that changed but still bog out
