Little update,,

Had to take a break because it started pouring rain so covered up the engine
and waiting for a about an hour (2 sandwiches, cold pops and some snacks).

Anyway I lowered that lower unit again on the 225hp and found that the
rubber sleeve, or rubber tube grommet that fits inside the impeller housing
cover got caught on the end of that copper pipe coming down from above.
Where the copper pipe has to fit into the impeller housing tubes there was
spun and partially was blocking the tube and flow. Now this would explain
both the gushing out the bottom and reduced pressure coming from that pee
hole. I hope. Havent started yet. But that copper pipe wasn't perfectly
round it had some kind of a dent looking at it, it wasn't perfectly
cemetrical so I sanded it a bit, took off the sharp edges, rounded it,
cleaned it then lubed it and lubed the female rubber pieces it is supposed
to mate into right down to that rubber grommet sleeve at the bottom which
was spun because of that oblonged shape copper.
Now I am only hoping that was what concerned me,,, will know in about later
when it stops raining, will report back.

Thanks for the words of encouragement,, fact is there is no day job as of
lately so I am happy to do this on my own.

So looks like this morning's job is dropping that lower end again and
seeing if there is something missing. There were a few extra parts in the
kit that i have for the impeller change , i thought I put every part back
on that I took off that was available to switch.

I think when putting it back together the tube that goes into the rubber
grommet thing there that is on the top of impeller housing might not have
completely went into that tube thing. I can only think that is the issue.

Or, I can go drop the boat in the river and see if it pees out much more
powerful,,, then everything is correct. This is my prediciment. I think
everything went back together properly, yet never noticed water coming out
from that space before, and never ran the engine on muffs in the driveway.

Would running the engine on muffs make the pee hole water tube outlet less
powerful?

Or should it be exactly the same on water on muffs on that back connection
??

Thanks again

Interesting update.

Got the 9.9 running Ok, I put the idle screw to 1.75 and started and it
ran
high so backed it out to where it was about at 4.25 it seemed to run ok
in
the driveway with earmuffs, idled very nice.
Thanks so much for the advice on that 9.9, so now that I cleaned the carb
and impeller I think the thermostat may be failing. It isn't a sal****er
unit but its been in salt water many times. About 15 years old. Either
the
muffs werent tight or the thermostat because I took the thermostate apart
and soaked that brass part in some CLR and cleaned the gunk out of there
and
put it back and really started peeing out that pee hole thing and idled
nice. Feel happy and proud I learned a lot on that 9.9.

So started the main engine the 225hp. Remember few days ago I changed the
impeller in that and thought all went well there. Now here is my
situation ,
I never started the engine in the driveway before with earmuffs, only
with
that thread in female part at the back where the pee hole view thing
pulls
out with sparkplug socket size wrench. So, for first time using the
earmuffs
I notice the pee hole squirter isn't as powerful as it was in the water.
Maybe half, And notice water gushing out between that space between lower
unit and shaft housing, not sure if that is supposed to gush out from
there,
I can only use the earmuffs in the driveway. I think maybe I might have
to
pull that lower part off again to see if I missed something when putting
it
back together. It was tricky as had to take the side cowl off to
disingage
that shifter rod.

So thats my plan in the morning. Unless one of you guys thinks that is
normal for a 225hp 1999 to run its water cooling system like that with
earmuffs. I should have paid closer attention to it before in the
driveway,
I only used that back feeder part. But in the river it ****es out much
more
powerful,

Any ideas?

thanks


Good on yer. Don't give up the day job yet but you are certainly
getting there.

Cheers,
