Guys, guys. This was a nice congenial boater thread. No need to ruin it. Ryan is asking good questions and should receive good answers.

Now back to Evinrudes. I have heard that the reeds can deteriorate over time. But sometimes they can build up with carbon not allowing them to seal correctly. Regardless, I believe that the reed is on track with the troubleshooting.

Guys, guys...Donne' started the ****. No one else.

But, I should have had more sense than to respond to the dumb ****, so my bad!

Ryan, sorry about that. Keep us posted. This is interesting.

So over the weekend I took her out on to Pewaukee Lake (larger lake so
I could have a bit of anonymity while smoking up the place) and did a
double treatment... Put some in the gas tank again and sprayed some
right into the carb.

Smoked like hell, but when it was done, the motor DID run better with
more power at high speeds (she planed out quicker), low speeds sounded
somewhat better and the sneezing frequency was reduced by about 50%,
basically from about once every 2-3 seconds to about once every 4-5 or
so seconds).

I'll take it out again this weekend and do another treatment just to
see if it reduces anymore and I'll bring somebody with me so I can
adjust the carb while they drive.

I'm not very optimistic that I'll get off that easy, but its a game
plan to follow!

Have fun and let us know how it turns out.


So I took it out again yesterday to play with it and give it another
dose of Seafoam...

When I came back in and was loading up on the trailer, I must have
been grumbling more than I thought, because another guy was launching
and came over to see what's up... One thing lead to another, and he
offered me $500 on the spot to take the boat and motor off my hands.

I took the money. lol BUT, he agreed with you folks here that from
the way it sounded he was pretty sure it was the reeds. Apparently he
rebuilds classic motors on the sides and either he'd rebuild it
depending on the condition of the innards, or he'd use it for parts to
rebuild others.

Either way, the problem is off my hands.

Thanks for the info, guys.

Ryan


If you are happy with the money, it was a good deal all around.
Those old motors will run forever if you don't mind working on them a
lot and can live with the 2 stroke quirks.
It sounds like you found the right guy.

What kind of boat are you thinking about now?

I can't say enough about how great the new 4 strokes are.
I suppose someone may have a horror story but I got 3000 hours out of
my 2002 merc and still sold it for a third of what I paid for it. I am
not a fanatic about maintenance and it did fine. I am almost 900 hours
into a 2012 Yamaha now with nothing at all done to it but oil changes
and a squirt of grease here and there.
I did lose 2 thermostats but neither were catastrophic failures, just
a nuisance running hot thing. OK if you went slow. (2 screw fix)
