Water flow
 

I am having water flow issues on one motor.
We have changed out the impellor- was perfect., back flushed everything.

Problem is that I am not getting good flow to strainer. One has the water going thru like a toilet bowl and Starboard is just about half that flow.

Any ideas? Changing water circulation pump this week.

Check your hoses for cracks. I've seen hoses with small cracks cause this problem. Sucking air.

i would also look for an obstruction in the drive itself, if something got wedged into the passages of the scx

I have been looking for leaks but none noticeable.

I was thinking this also- It started Shootout weekend.

Now how? I guess pull drive? I looked at intake holes in nose and they appear clear. We flushed water back out also.

I had this same issue, I put a brand new mercury pump housing on, it had a casting flaw. When I installed it, in between the 2 bolts that are close, the new housing had a hairline small crack, I thought it was a drip from hose, but it wasnt, I replaced with a borrowed older housing. Full pumping, no problems. Just that little air and it made erratic, half pumping situation. Good luck!

FYI this was 4 weeks ago

Did you check the connection/ fitting at the transom assy for blockage ?

Its Dark back there lol. With the Stellings boxes Hmmm. Need to see about that. Might be able to pull hose lose in box?

What size hose is this? I might just get several feet and replace.

As for the impeller housing its the Stainless steel from Hardin( I think).
Bad part is tanks are Full and I do not want that sitting all winter.

Better to fix it now, burn the gas, and be able to sleep at night....lol. I hope it's simple for you, good luck
