I’m having a problem with my jet ski it’s a 2005 Honda f12 aquatrax when I took it out it was going about 53 mph but then 2 hours later it is only going about 37 mph do you have any idea what it can be? I changed the spark plugs and oil
There is an enrichener in the EFI system for cold starting.. sometimes it fouls the plugs put a dab of anti seize on the new plugs to keep them from seizing in the heads,
I have a Yamaha SX190 jet boat that I bought with 15 hours on the engine, last year. It too doesn't go as fast as it should. I will try the same. Thanks!
Hello friend, I have a Jetski Yamaha XL800 before I ran at 60 mph and now only at 30 mph I already changed spark plugs and nothing can you help me thanks
Glad you got it fixed my dude
@Sean B, yeah I'm glad too. It was the spark plugs.

How many hours did u have on the spark plugs ?
@alexjrful, I think I had like 55 hours.
I have a Yamaha SX190 jet boat that I bought with 15 hours on the engine, last year. It too doesn't go as fast as it should. I will try the same. Thanks!
@Darrell Brown, yeah, maybe it needs an oil change and replacing the spark plug. Please let me know the outcome! Thanks 👍

Were you able fix it? if so how?
1987 Yamaha wave jammer 500 won't go past 3 miles an hr. Do u have any idea what it could be
@Cuauhtemoc Chavez, I'm not a mechanic but based on my experiences I would check under your Waverunner (impeller). Second check your spark plugs.
Thank you for this video!
I have had this happen on my two jetskis.
It’s good that is an easy fix.👍
