Location: Bloomington, MN | The 2005 Honda is running pretty rough at low speed. I brought into the shop with full intentions for having the full nine yards of maintenence done even though I can handle the basics. Appartently the 3 carbs are clogged, and I have always used 91 oct. + a stabill like conditioner. The motor just runs rough at idle, but apparently the carbuerators need an overhall. The cost for this procedure to be done is close to $1000!!!! This includes new plugs, oil change, and new filter, lower unit lube. Is this a normal cost of up keep for a 6 year old with low hours on a Honda???? Never use any fuel that has ethanol in it. I always thought that 91 oct. was free of this evil element, and due the hope and change going on they will glady put the B-Screws to you! Since I work constantly and the boat is there, and I need it this weekend...Labor Day cocktails won't be on me! The new 70 hp Yamaha tiller looks fantastic, but since it requires me having a entire new boat, that ain't happening!

Location: Ames, Iowa | Do the plugs, oil change, filter and lower unit yourself. Plugs might be tough without the right tool. I had the jets cleaned out in the carbs due to gumming after I bought roughly the same motor and it sat over winter with old gas in it. That was 3 years ago and it cost me $137 at Longville Lakes Marine in Longville, MN. I was off the water for a day. That's a great motor and with the right TLC it'll be great for a long time. | |

| Hey Clark, hope you and family are doing well.
I'm on the same page with DJ on this. The most likely culprit is a bit of varnish in the idle jets - they get clogged easiest because they have the smallest orafice.
In addition to plugs, fluids and filters you can also try this: Dump the fuel tank into your almost full daily driver, and drain the fuel out of the fuel hose and the carbs (directions are in the manual - hose bib on the side of the fuel bowl with a small drain screw that you loosen and then tighten back up to close). Put fresh fuel in the tank with a dose of Sea Foam and run it for a while in the driveway with your rabbit ears for water. If you only have a small bit of schmutz in the carbs, or the problem is bad gas or plugs, this will have taken care of your problem.
You can also try shooting a bit of carb cleaner around the carb bases while the engine is running. If the problem is a loose or deteriorated carb base gasket you will hear a change in the engine sound for a second when the cleaner gets sucked into the crack.
If the above doesn't solve the problem you should be able to get someone to pull and clean the carbs for a lot less than $1k. With a 2005 engine it is pretty doubtful that you are looking at anything worse than varnish or a bit of crud.
I've done plugs, fluids filters and carb draining on my Honda 50, and all were pretty straightforward jobs.
Regards from the Tryners.
