Its the depth Ive found the issue. I guess ill have to get out and about to have a look. Technically the manual says water up and just over the foil height i think. But i was wondering if its covering the water intake if thats really enough.
Boatfish. I've been watching this post now for a few days even offering a few options that you shot down. And it seems your real problem is the hydrofoil installed on the engine. I'm sure it is installed with a few bolts and nuts so why not take some time and remove it to verify everything internally is working in a simple trash can setup and then reinstall it afterwards? Sounds like you're putting in a ton of effort to make some makeshift container to use briefly to make sure the water pump is working when a little time and elbow grease would solve your problem quickly... You could look for a long time and try all types of contraptions and just as easily remove the foil and do the test so quickly and move on... Don't reinvent the wheel! JMHO!
gm I made that same suggestion in post #3. I have been trying to make other recommendations, but like you said no reason to reinvent the wheel. Although I believe the problem is Boatfisho is flushing after salt water use versus just doing a water pump test. I think that is why the aversion to removing the foil every time.
I have a large storage tub that's 25" long at the top and 16" deep. Sounds like the OP is going to have to build to fit or remove the foil. Is the foil REALLY necessary??

Easiest solution is a $10 plastic garbage can. If it's too high, cut it down. If it's too low, mount it on some blocks.
On my Yamaha F90, I had a similar problem - got a pair of rectangular generic muffs, and used person power to press the sides in - once it started peeing, it continued.
