Last fall on the water, I noticed had very little (<2 psi) water pressure at idle and couldn't get 10psi unless I had the RPMs up and moving fairly quickly. I got around to taking the lower unit off and believe I found the culprit. I think the gasket had a tear in it which was causing the impeller to not create enough of a vacuum to pull in water until at high RPMs. Looking at the impeller itself, it looks fine to me, but I figure I might as well replace it now while it's all apart.

I inherited the boat from my dad so I don't have all of the original manuals on the engine for part numbers. I do know it's a 200 so I'm hoping that narrows it down enough. Here is a picture of the parts I'm working with and hope to replace.

I've searched many different sites, but I can't seem to locate the water pump kit I need. I've seen some that look similar to what I have, but not an exact match. Hopefully some here has some guidance for me... thanks!
