got this wierd problem all of a sudden with my 1990 150 yamaha 2 stroke. has always started easily. now it wont start. i have spark and the plugs are wet. if i shoot some starting fluid in it it will fire right up and keep running great as always. if i shut it off it will start back up fine...
at high trolling speeds my 1990 9.9 4 stroke hi thrust will stall out and die after a minute or so. usually if i pump the bulb it will buy it another minute. sounds like a fuel pump but its new (the old one was leaking gas into the crankcase). bulb is always hard and its running off the main...
1990 yamaha 150. was running great and halfway through the day the motor now is 1) sluggish to plane, 2) will top out at 4000rpms and then drops to 3400rpms after a few seconds. it starts and idles and puts around great but its like it drops a cylinder at high rpms.
initially i thought it was...
all of a sudden my 1990 150 can only get to about 3500rpms and appears to be down at least one cylinder. i do get the occasional "full power" surge. when at idle i can pull the wires to the bottom cyl in each bank and it doesnt change rpms at all so it seems they might be the culprit.
it has...
my 1990 yamaha 150 has been running perfect for along time. yesterday i was out and everything was good all day on the water then it was having a hard time getting on a plane and couldnt reach WOT rpms. it was lacking power and at WOT like a cyl or two was dragging. at WOT i could occasionally...
ive got a 1990 150hp yamaha that runs perfect. the only thing is that the steering arm and pivot tube (the thing that the motor tilts on mounted to the transom and the steering rod goes through) are very rusty.
it looks like the only thing holding the motor up and i am worried about the rust...
got twin 1996 evinrude 115 ocean pros. was cruising along at near full throttle when the port motor died and kicked up rather violently. would not restart. looked down, the tilt cyinder had been cracked in the process and all the fluid leaked out. now i have no spark to that motor but it will...
Is there a definitive way to tell if the head gasket is blown?
I have a 1990 Yamaha 150 2 stroke. I fired it up and took off and in about 100 yards the overheat alarm went off, i stopped and shut it down within seconds. seaweed had blocked the intake. i fired it up a few minutes later and i...
i have an early 90's 9.9 4 stroke hi thrust, its equipped with a remote throttle and ignition control i believe model 703. it has fast idle, throttle/shift lever and ignition. my question is how do i choke it? its hard to start when its cold and i assumed the fast idle lever was also a choke but...
Im getting an oily film on the water around my early 90's 9.9 4 stroke. It appears to be from the exhaust because there is a little oil residue around the exhaust port. Is this normal at all? it runs great but i just got it and wonder if its from unadjusted valves or maybe bad rings. When i got...
Can i use some kind of non-marine paint? i have crappy looking bottom paint. Id prefer to remove it altogether but its too hard. I dont like the rough texture of the bottom paint and since i dont moor it all i want to do it make it look nice. The standard bottom paint is expensive, rough and...
It may be a little late but i just bought a grady white with a 1990 yamaha 150 2 stroke "precision blend" outboard. How good are these motors and is there anything quirky about them that i should know about? I've had several outboards but never a yamaha. the motor has very low hours as well...
just bought a boat with a 1990 yamaha 9.9 4 stroke for a kicker. i have never run it but when i checked the oil it smelled like gas even though it was very clean looking oil. Why would this be? preliminary reseach says running too rich or too cold. even though its old it has extremely low hours...
i just bought a boat that has some shoddy bottom paint. I dont moor the boat so i would like to remove it, is there a good way or should i just repaint it?
i am looking at a boat (still, if you've followed my posts) that has pock marks and alot of gelcoat blisters. for reference what does it usually cost to have the hull re-gelcoated? this is on a 25 footer. the boat is so cheap and otherwise excellent that it might be worth it. thanks.
