ray this ones for you

[curjones]

I have a 175 cover on my boat. The transom Id says 220 aeto. I called a local dealer and they told me that yahama doesn't make a 220 and that model numbers don't end in o or 0. In one of my eariler post you told me if it is a 220, I would have to use premium fuel because of knock sensors which I have. What is the deal I know you have the answer. I need carb rebuild kits and fuel pumps. I went to the Yamaha parts site and they dont list 220 either. I did find reference to 6g7 in some other online parts dealers. I also found the serial # stamped on a plug on the block and the #'s 6g5-00. You're the man. and anyone else who knows let-er-rip

I got an email today they said the model number was an overseas number, any one know if there is a cross refrence #

The 220 sold in the states was called a V-6 Special and had that designation in the model number. It had noticable differences in that the top carb had a throtle position sensor and the heads had a knock sensor in the starbord side as well a the standard heat sensor and a computer module mounted on the rear.<br /> For the carb kits, if the carbs are Niki or teiki will determine the kit you use. One has a single bowl and one has a double bowl. There were two different versions of the single bowl with different size floats. The other parts were the same in the kits.<br /> The floats were either short and stubby or long and lean. The short stubby ones will work in either.<br /> There were very few 84 models sold in the states and I don't have a cross reference for overseas models.

Re: ray this ones for you

you're right on Ray, The carbs are dual float, teki. Have seen the TPS on top, two thermo sensors on top of heads. Will look this up and try to remember ;the starbord is that the right side or left as you are driving the boat (I'm a cadet)the reason I'm asking is there are two different types of sensors about mid point of the heads one is a single wire on the left side the other is a two wire. What pn# is the carb kit or who can I buy parts from that will understand what I'm looking for. Is this motor a 220 HP? I was wondering if the 220 stood for cubic inch because they were sold overseas where metric is the standard of measure

Re: ray this ones for you

Ive got to back up here. Assumed that it was dual float got home from work and they look like a single float in the middle. They still haven't delivered my manual. I got a number for tech support and the guy told me to look at v6-special. There is none listed for 1984 but v6 special is listed in 1985 and the dual float is listed in 1986 under a J series there were two v6models in 1985 and 1986. Without over thinking this thing I'm betting the single float carbs are the same. I am decarbing the engine now before I go through a rebuild putting in my second dose of seafoam in right now . 1st dose didn't look that bad. Any more advice

Re: ray this ones for you

The single sensor wire is for the knock detector. That motor does require 93 octane fuel to keep it from going into retarded timing. detonation is most likely to occur when when planening off the boat The dual wire sensors are for heat. The needle and seat and bowl gasket should be the same for all of the V-6 single float models to rebuild the carbs. A worn bowl gasket can give a hesitation in planening off but what you are describing sounds more like a safe mode from detonation due to too low an octane. Starboard is the right side looking toward the front of the boat.

Re: ray this ones for you

interesting thread. i have just come across one of these engines but the module you mention is missing and the tps plug goes no where. you mention 93 octane gas, that would account for my lower then usual compressions. how will this motor run without the tps/controller and knock gear. how the heck am i going to hear it ping over the rattle?

Re: ray this ones for you

If the TPS and computer module have been disconnected or removed, which you can do the motor will run very poorly since the timing will be locked at -7 degrees unless the stator has been changed to a manual one to advance the timing. Low compression will not be caused by this removal or disconnect.

Re: ray this ones for you

the low compression part i understand. ill check the timing tomorrow but i believe the stator wouldve been changed because this little beauty has been on fire at some point yet none of the wiring looks melted.
