Smoother intake?

[FSHER]

Hello,
Another miss regarding assembly/build quality on my Yamaha 210 FSH is the intake in general. Both intake screens/grates have gaps where they meet the hull and the back sides of the intake ducts are 1/4 or more higher than where it connects to the impeller housing(I think that's what they connect to). Am I wrong in thinking that the intake should be 100% smooth flowing? I'm sure the affect is very little to negligible but maybe it s not? Maybe if the intake was smooth the water could flow better and decrease issues slightly. Is the flow disturbed just enough to make it easier for weeds to get tangled up?

Is it crazy to want to fill the gaps to smooth them out and or maybe file the intake ducts down to make them level with the impeller housing?

Give us some pictures........but you are correct most gates use caulk to smooth out the gaps......I getting ready to pull my jets for maintenance and recalk the gate gaps ..........my port engine is picking up the sea grass in the gaps a little more than I like.

I fill mine with silicone by hand and smooth them out - it won't last super long, but it'll help for the season.
