I'm pretty sure our T37 is powered by a W40. We overheated while motoring to our new slip at NAS Pensacola and if I were a betting man, I'd put my money on the impeller. I read that it should be a Sherwood 12 blade.

Did I get the right one?

That appears to be the correct impeller. I recently had a series of overheats on my W50. What I found so far is the cover plate is worn where the impeller rubs against it. This was causing bypassing of the water flow from discharge to suction and not enough flow through the pump. I couldn't get my pulley to come off so I could replace the pump with the spare (And the yard guys have twisted an allen wrench in the attempt!). I replaced the cover plate with the spare and things are better.

Spare pump cover plate on the left. In place pump on the right.

Once I can get the old pump off, I am going to install the spare.
