Fantastic pump...if all you want is to push water around in one direction.
After a year of running this pump on my 40B I have to say I am very disappointed. Especially after all the hype. Something I've never fallen prey to before until now.
1) I started out running it at 30% max as the flow was so strong. Today I'm up to 60% as it seems to have lost power over the last year.
2) Pushes water yes but keeps very little if anything suspended in the water column. Just keeps moving it until it gets caught up in the rock at the opposite end from the pump. Which for me has led to major detritus buildup in that area.
3) Paddle life is short. Bushing life is even shorter. Seems the constant water pressure causes them to warp over time. Also noticed the rubber bushings become easily degraded by calcium deposits. Removing them means destroying them. Which is a big problem as they no longer make them for my pump.
4) Must replace old paddles with new (not so improved) paddles in order to get rubber bushings that fit. Bushings & Paddles have all been replaced, remade.
5) It was easier for me to remove, rebuild and replace a carburetor on a 67 Chevy then it was to change out the paddles on this pump. What a PITA! I won't be doing it again. Hopefully it'll run as is until next year when I'll be able to go back to the tried and true.
