Hello, new to this forum. I have a 1953 Scott Atwater 10HP Gold Pennant. Can anyone tell me where the water intake is located and I’d the water discharge is the series of holes on the back center of the lower unit. Many thanks, Mark

Nice motor!
I have a 53 Firestoone, same motor. I ran real fast with mine, noisey but very much fun. Welcome to AOMCI!!

It’s likely the impeller. A few tips:
Be careful taking this all apart. I’ve done a few of them in the past few years and the driveshaft is often stuck in the crank. Don’t even think about using a hammer on the anti-cav plate below the pump housing, it is very fragile. Work from the top end by loosening the powerhead and rocking it to break the driveshaft free of the crank. I believe there are folks that rebuild these impellers, so if you have the core, you may be able to get a replacement. I used a very inexpensive Honda impeller, but a few modifications were necessary. Its use required making sure that the original impeller insert is flat on the bottom, not deformed from corrosion underneath and trimming down the height of the impeller insert. Then a strip of brass was formed and soldered to reduce the ID of the insert. The motors have pumped well with these mods, but once done the motor cannot be returned to stock without replacing the pump insert. On other Scotts, I’ve used the Honda insert, modified, but I’ve never tried that with the Pennant (straight leg) motors. As noted, these motors are pretty loud. I’m considering some sound deadening liner on the covers; I think most of the noise is from covers rattling.
Best of luck, hope to hear about one more on the water.
