Carver Owners Forum

With gasoline, I would not have it cleaned, I would have it removed. I am not sure if you did this or not? Also, if you did have the fuel removed and refilled with new fuel from the marina, is anyone else at the marina having fuel issues? It is not at all uncommon to get "new" fuel that is bad especially at the beginning or end of the season.
You could change the housings and filters, but you will most likely continue to have the same issues until the BS in the tank is filtered out. You may want to consider just keeping several extra (cheap) filters on the boat and run the heck out of it.
When your RPM's are moving it's most likely not because of debris in the injectors, its because of low fuel flow due to clogged filters. The cheap filters clog at the surface rather quickly, the raco filters will capture at the surface and deeper into the filter giving a longer life, but for your problem, it may be cheaper to keep swapping the OE filters.

my 2 cents. best of luck to you.

Tom, I did not mean clean the gas. They cleaned the tank. First two times they extracted, they ended up leaving gunk around. So this time they put KI (I think he said) and agitated the tank content by spraying from one end to the walls and all and after 10-15 minutes sucked it all out. So he actually extracted, as they attempted the first 2 times. I do not think its the gas station issue. there are 2 of them across from my dock and I used both to get gas from. Also I know for a fact that thank had foul fuel to begin with when I purchased it (actually I found out after going through all the mess that I been through). I aggree with you on the filter issue, thats what I been doing. Get them from Amazon and switching everytime they get clogged. I will do that until I know the problem is completely gone, then switch to a better filter. how can I tell which raco filter to get, is anyone using it on their carver 356 here, that can tell me?

If you just want to use a Racor spin on with your existing housing, the dealer should be able to cross reference from your existing filter #. If you want to change to a water separating Racor filter and housing, your existing housing most likely has 3/8 NPT female threads in and out. I would get a set up rated for at least 80gph or 120gph if you have a return line from the fuel pump. Of course make sure it is rated for gasoline.

10 micron filters will catch smaller particles and hopefully keep any thing from getting to your injectors. Mike

Mike, will it be ok to use 10 micron in 356 aft cabin mercur gas engines? I mean will it affect the flow, etc.? I got sidetracked, I was trying to find out what were the original filters on 2000 carver 356? maybe I can call carver to see if they can tell me.

Cpoint, I would rather have to change a plugged filter than have to remove and have my injectors cleaned or replaced. I think 10 microns is standard, if not Viper will correct me. You'd be better off call Mercruiser the engine manufacture than Carver for that info. Mike

Thanks, I will call the engine manufacturer. I know what you mean about fuel injectors, in my case I had to replace them at $3k for injectors, + labor

I just checked their site and see that it is quicksilver part# 802893Q. What I have on mine is 802893Q01. Anyone know difference between 35-802893Q and 35-802893Q01. What dows 01 at end signify?

Same filter. 35-802893Q is the old number and has been superseded to 35-802893Q01. You can also use 35-802893T which is the Mercury label instead of Quicksilver. The Merc is about $4 cheaper up here. These are the standard OEM filters for Merc inboards of that vintage. I'm pretty sure these are 25 micron and that it's the standard in gas apps.

Thanks, that's what I thought. I did see both online, they both say 25 micron. so if that's what the original was, which seems to be the case, I should stick with 25 micron. I assume 10 micron may cut flow down? I am guessing, I have no idea.
