Thanks yeah I'm not putting it in gear because I'm afraid to if the idle is as high as the tach is reading.My Faria tach is wired correctly but there has been a question about if the pole setting on the rear of the tach is set correctly,that's why I got the Tiny Tach to compare.I do have a question about the set up on the Tiny Tach but I think I got it right as the other two settings were worse. A standard two stroke 2 cyl spark plug will fire with each revolution doesn't it? I couldn't find any info on my engine about that but I assume that's correct. If it is then it should be giving me correct readings and then that puts me at a total loss. I think I'm going to get up the courage and go ahead and put it in gear. If it goes into gear smoothly than I'm not going to worry about it,if not then I have to find a way to get it down...wish me luck!

P.S. When I first start it I'm putting it in fast idle for a few minutes until it warms up a little bit then I'm dropping it down to my lowest rpm setting,that's what your hearing.

Alan,

Don't gear at high revs without load, won't go into gear smoothly, you need to turn CCW your idle carb screw to lower revs to suggested revs. If other 2 TT settings gave worst readings, then the one you are currently reading should be the right one. If counting with siamese Ignition Coil you have 2 sparks per one engine revolution and assume one spark per revolution if counting with individual coils per cylinder.

Happy Boating

OK then the diagram I'm looking at has 2 CDM's which is what on my engine we are talking about when we say coils correct? So then it is firing one time per revolution which would make my setting correct and is the default setting. That means the readings are correct and I need to get back to work and get down to at least 1000 correct? I guess it's time to check the spark which I was going to do anyway. Thanks for your help.

I'm going to drop the idle down until it stalls this time out. It has stalled on be before but then I don't think I had done a link and sync as good as it is now. I also have been lowering it until it sounds like it's sounds likes it' lugging but this time after a good warm up I'll go until it actually stalls and see were I'm at. I use another forum too and someone said he was sure something in the carb was not clean enough so if I can't get it down I'll take off the carb for the third time. The second time I didn't clean only worked on the float and inlet needle so maybe I didn't get it clean enough the first time...we shall see.

Once engine is sufficiently warmed, drop idle rpm to 1 K. Shift forward, let engine idle for some minutes to see what happens ? Use muffs preferably, post results. Haven't seen a carb issue in which you experience high revs unless butterfly is not returning fully to its home position. Lube butterfly outside and inside shaft bushings with thin oil, lube while rotating shaft back and forth to achieve a smooth operation.

OK thanks. The carb sure looks clean to me.This time I used Mercury Power Tune to clean it. I blew through the gas intake,if that's what it's called,and no air got past the inlet needle so that's sealing properly.Looking through the tube that goes down into the float from the top it looked like it might of been dirty but it looked nice and clean when I got none with it. I'm going to say if this cleaning doesn't fix it it's not a dirty carb.Next up will be spark which I didn't do today because I was cleaning the carb.Will give a full report tomorrow after running the motor and attempting to get the rpm down.

I just ran it in a can. Dont have no rpm meter. Sounded faily quite so i geared it and switched smoothly. If it sounds good then put it into gear already, leave that tach for the birds

Some issues :

Squirting Power Tuner will not clean carb interior, just carb throat and engine internals. Does your butterfly fully opens back when closed for first cold starts. Check that is not jamming somewhere, lightly lube both side bushings for smooth butterfly return operation.

I took the carb apart for cleaning and used the power tuner as a carp cleaner to clean out all the holes then let it soak overnight. The butterfly works as it should opens fully and snaps back to closed every time. You can see through most of the holes in the carb and none of them were clogged or looked dirty,I have a small light made for firearms that worked good for that.I have to believe now that if the problem still exists it's something else causing it...fingers crossed.

Just wondered if you went to the Mercury forum section to check your problem? Sure most folks don't look at our inflatable section and they look very busy over there.

I did and I got very few replies most coming from inflatable boat people. I asked for help on another forum too and got little help.One guy insisted I had the tach on the wrong setting.He went so far as to add links to different gauge companies instructions for gauges made for different makes of engines. Finally I took a picture of my instructions,which were very different,then thanked him for taking the time to try and help me. He probably still thinks I am wrong and is mad because I didn't listen to him.

I really started this thread so other people,especially new boaters like myself could learn something about setting up and using an inflatable boat.Posting about my engine problem is just part of that learning process and If I get help here too that makes it all the more better.

Lower idle rpm to 1 K >>>>> go for a wot test >>>>>> report back findings.

I'll be testing my idle on muffs tomorrow,I expect it to be good, then I can put it in the water after I get it registered!

A little aside,I got my dog a doggy life preserver the other day even though he's a super swimmer.If for some reason he should have to stay afloat for a long time in an emergency he'll be able to do it.Here he is jumping off a dock.

Not trying to rain on your parade but
Don't you think you should have gotten the boat and trailer registered before you did all this work?
And please don't say registration is simple.
It never is.

Good luck!


So overall decent trip (did not have to row). Couple issues: When in gear going from fast throttle to idle speeds it almost always cuts off but restarts easy. another issue was i do feel its either sucking air from somewhere or its misfiring i don't know the difference (thinking its sucking air from fuel pump). I am hoping these are easy fixes. It does seem to idle a little high when when i turn clockwise half turn it seems like its not getting enough fuel and chokes until it finally cuts off. So overall felt like it was running decent at mid to high rpm's.
Now the boat issues: realized after i couldnt get on a plane that my keel was deflated flat. Doesnt make sense to me because the keel is always covered by the bow bag and there is no reason it should be flat (inflated it before i left my house this morning). On the good note, while i was crabbing a school of dolphins came to greet me which was cool.

Why isn't it? I bought it brand new and I had no problems with the last new boat I bought.The trailer is already registered and I bought that new also.

That is very cool. I haven't had a chance to put mine back together and test.I'm thinking if I get done doing all the simple repairs and tests that I think I can do and it still doesn't run right I'm going to take it in. I was directed to what many people around here say is a really good shop so will use their services if need be.
