New to the forum. After year and a half of algae and excuses from pool guy I found TFP and figured what was really going on. Got the TFtest kit, found CYA and FC were 0, fired pool guy, cleaned and balanced pool in 8 days and more recently installed a SWG.
Now the 8 yr old single speed Marathon motor is on its way out. Bearings have been going for awhile and as of yesterday I can only get an hour or so a day before it overheats and shuts off. Rather than rebuild it I want to replace it with a 2 speed pump/motor for power savings. I've read through a lot of other posts and my question is should I replace the entire pump or just replace/upgrade the motor?
My existing 10 yr old Hayward Super Pump SP2607X10 hasn't had any real problems as far as I can tell. It looks like a 2 speed replacement motor (AO Smith 2 speed 1 hp STS1102) would run about $307, and once I add Hayward Go Kit (salt water type - is that really necessary?) and a switch for the 2 speed I'd be at about $365 just to replace/upgrade the motor. Alternatively for an entirely new pump I was looking at the Pentair Superflo 2 Speed 1 hp (340042) which would run about $428. I'm new to all this so I worry that I'm missing something, but it seems like it would be worth the extra $60 to go ahead and replace the entire pump.
Also any thoughts on the choice of the Superflo and motor size would be appreciated. Existing motor is already on 230V so that's not a problem.
Thanks in advance.
