Hello I just purchased my first boat. Its a 1987 18ft Bayliner bass boat. With a 1983 200hp Johnson on the back the numbers on the motor are J200TXCTD the cover says Magflash Sea Horse. I checked the compression before buying and it read 115,120,120,120,118,110 And from what I have read thats ok. It had been sitting a couple years so I drained the old fuel and mixed a can of seafoam with a couple gallons of premium and she cranked write up and purred like a kitten reved up nice and smooth. had it in a tub of water and water pump worked great. so I took her out in the bay the next morning. Idled through the canal great go to give it some gas and it just dont do anything past 1/4 throttle so I figure ill idle around for a bit and give the seafoam a chance to clean up the carbs. Give it a bunch of gas and she reluctantly gets up on a plane now and once planeing has all the power in the world I got scared a couple times and was only at 4000 rpms so im zipping across the bay and over five minutes time slowly lose power but she lets me idle back to dock anything over idle just bogs and dies. once at dock wont even start now not a spuder or nothin. I noticed when I went to pull the carbs off theres no filter anywhere but i cant find anything about a filter for this motor. I was thinking it might have been sucking in the foam falling from the cover. I took apart a carb and it looks spottles i was realy kinda hopin it was just gummed up carbs. need help im soo new to outboards
Took her down to the boat ramp and she runs great but I think it should have more power a 200 on a bass boat i would think i should have no problem getting up to plaining speed. Yet its still a stuggle then once plaining all the power in the world. So I brought her right back to dock so i dont do anymore damage. I pulled one carb apart she lookes spotless inside checked compresion still the same as before .
