2005 Yamaha Fuel Pump Problems

I am having issues with clogging/failure of the Hi Pressure Fuel Filter. I have a 2005 2320 SL with 250 Yami 4 stroke and the boat is in the shop for the second time in less than 2 yrs they have replaced Hi Pressure Pump. I am finding out that are a few others experiencing the same problem with the 2005 model year. Yamaha is claiming that this was not a warranty issue sighting fuel contamination. I have a few buddies with Yamaha 4 strokes ('04, '06 and '07) who live and fish and gas up in the same areas I do and none of them have had this problem. This problem again seems to be centered around the 2005 model year. Has anyone else experienced anything similar? I would like to add that I change all my filters, oil and plugs and regularly use Ring Free. Filters never show any residue and the plugs are never fouled but I still replace all every 100 hrs.

re: 2005 Yamaha Fuel Pump Problems

I spent about 4000 dollars trying to get a simular problem fixed. It is a long process to explain, i had to clean out my fuel tank twice. and in order to keep the boat running good i had to clean my VST Filter about ever 20 hours. Ill PM you my number since it is a long story, If you are interested. My Problem was on my 2002 25 parker also and my yamaha os 25o Chris

Somewhat related, but not. Have a Honda 225 on my 25' Whaler that was clogging the hp filter as well. Not sediment, but water. My vent was ingesting water when I would stuff the bow into a big swell, this happens out there. The water would pass all the filters and water seps after the boat would sit and the water would settle. First startup after a rough water crossing, the pickup on the tank would suck up pure water and it would run past everything, as pure water does and colapse the hp filter, stalling the motor. The fix- clean out the tank and install a stainless flush mounted fuel vent. Problem solved. May not be your exact problem, but a $25 flush vent is cheap insurance.. Your problem sounds more like a bad series of pumps, hopefully yammie steps up to the plate. Fuel problems suck, they are proof that Murphy is watching..

Louie sorry to hear about your outboard ordeal. I hope Yamaha steps up as well and takes care of this under warranty. P.S you know you are always welcome to share a spot on rail with me on the High Five.

Have you tried a 2 micron Racor filter? The regular Racor filter is 10 micron. I hear Yamaha was having problems like yours so they actually started selling a 2 micron fuel/water separator under the Yamaha brand name. Hmmmm.....
