Ive always been told to never run it much above idle in a bucket. The impeller provides water for cooling at idle and reverse speeds but isn’t enough for higher rpm’s. Forward movement forces water in the intake pickup just to the rear of the prop to provide ample water for cooling.

sounds good.......i always started 1 1/2 turns out on slow, 3/4 out on fast.........end up after on the water, bout 5/8 out on fast, 1 1/4 on slow............each is there own........till ya run under load..........then proping will need a tweek, without knowing rpm, its all lost for peak performance.........

Slow speed is set at about 7/8 out from closed. I was able to dial this in very well and get a good flat idle. An 1/8-1/4 more lean and it will cut out. The high speed is at 3/4 though I really did not run it up over half throttle in the bucket in neutral. I figured that would need full throttle which requires one to be in forward. I was not sure if I could spin the prop in the bucket so I did not especially since i nabbed my neighbors bucket of the curb:shhh:

the 30hp sounds good..........where did you preset your slow and high jets at ?.......
now to get er on the water to dial them in...............remember to start with the fast speed first, then you can tweek the slow speed once tuned in on fast......

Yes, Joe had warned me about using starting fluid. The cylinders were oiled through the plug holes after the last no start and I just did a single spray to confirm that it was a no fuel issue and that the plugs were firing under compression.

I ran her a bit till she got warm and I can even get it started off the pull rope with no problem. I was surprised at the amount of oil in the water in the bucket, quite a bit. Never owned a two stroke that was not a dirt-bike or chain saw. This thing is pretty smokey, could be the extra oil I added to the cylinders taking a while to burn out. I have the gas at 24:1 per the manual. Need to do the recovery mod.

Should I check (drain) the lower unit oil or wait for more than 5 min of bucket run time to make sure I did a good job sealing it up?

I would be very careful with the starting fluid, if the motor is not getting enough fuel to start, it also has no oil to lubricate it. Pistons can score in seconds.

While I was waiting for my electronics I decided to work on some finishing touches. I NAPA aluminum brightered the whole thing and hit it with scotch-bright. Trey came through with the numbers and mini-feather craft sticker and they look great.



Joe came through the other day and I puttered around not doing any real work and messed with the motor. I was so excited I didn't take any pics. Well I got it back together. Tested the spark plugs and hears a good sharp crack of electricity and could even see the spark in bright daylight. So I hooked everything up and got a bigger bucket.



At least this time I got a few sputtering runs off the starting fluid and saw water pumping but it would not run. The sputter on fluid let me know it was a fuel problem which would have to wait for another day.

I pulled the carb off and was surprised to see how clean inside the motor was.



The carb was pretty clean but had a deposit in the bottom of the bowl.


Messing with cleaning the bowl I found that the tiny passage to the slow speed circuit was totally blocked with crud.

Put it all back together and.....

Good luck with the new parts Larry, did you replace the impeller already, I can't remember?
