I’ve been having a mind numbingly odd issue with my Yamaha 25hp for the last month or so.
I ran out of gas at WOT about 300 yds from the boat ramp. Tried to get the motor started, failed. Got it back to the ramp, busted my bowl gasket due to it being flooded. Rebuilt the carb.
Since the...
The folks over at Crowley Marine were able to get it answered. Makes sense, as there was no water running through it at the time. Posting this in hopes that it helps someone in the future. Thanks all
I believe the imp shredded while using a bad water hose performing repairs. Not enough water getting in I guess. I'll be dropping the LU this week. Hopefully all the little chunks will turn up without issue.
Unfortunately Yammy's website does not have manuals dating back far enough for my model...
My main question is: does anyone definitively know what this indicator light is trying to warn me of? If it's a low oil level or temp gauge then I know it is a faulty indicator, but if it is an indicator for no/low oil pressure or water pressure, then I know I've got a problem on my hands...
The tank was more than halfway full. I'm thinking I'll drain the tank, clean, refill with good fresh oil, and check again. I'm debating on deleting the oiler system all together. The fact that this light comes on so consistently with the flywheel makes me skeptical of how much information it...
This could be a stupid question, but would anyone be able to enlighten me as to what the emergency signal light... signals?
Last night I took my 25 2 stroke out for the first time since thanksgiving, and the first time since rebuilding the fuel pump.
My impeller was shredded and the motor was...
Hello. I have been unable to locate a rebuild kit or part number for the fuel pump on my 1991 Yamaha 25hp 2 stroke. I have called up my local yam dealer and came up short handed. I have seen people on this forum talk about rebuilding or replacing them, but I have had no such luck finding a kit...
Took it out on the water. The impeller is not nearly as powerful or cold as I’d like. What other seals should I be checking out? New housing gasket and new housing. I’ve blown out the passage ways with an air compressor. Surely the water outside of the housing has something to do with it…. Right?
Very general question that I have not been able to find the answer to online:
Should there be water in the lower outside the impeller housing? I have been fighting with a 4hp trying to get it to pump water. New housing and a second new impeller and I’m finally getting water inside a bucket…...
Before I replaced the impeller I had some water coming out, but not nearly enough. After replacing I had the same amount, if not less. I then shoved a pipe cleaner as far in the TT as I could and the water flow stopped completely. This is why I suspect an internal passageway is severely blocked...
I’ve pulled the CDI, carb, gas tank, pull start, everything. I have removed every bolt I can find. Do I need to hit it with the pry bar, or is there a secret bolt I’m missing?
I have a 1993 (according to model number) 2 stroke Yamaha 4hp. I am trying to figure out why it’s not putting water out through the tell tale (I’ve replaced and rechecked the impeller 3 times). After exhausting my options I’ve decided to remove the powerhead to take a closer look at the...
After toying with it for a bit I realized the clutch was not fully engaged in reverse when I attached the linkage with the barrel nut. After prying the lower linkage into reverse while spinning the prop I was able to get everything synced up correctly. No more clicks/rattles/knocks in neural...
