What size batteries would i need to go farther? can i put a bigger hub motor in it

Are you measuring this to to the tyre, the rim or the actual hub? Check the silly simple stuff first. Are they matching rims? Are they matching tyres? Are they BOTH at the same correct air pressure for where you are driving, (Hard for road, soft for serious off road)? Same 'size' rims can be a slightly different shape between manufacturers. Are you using 'spacers' between the hub and rim? If you are check they are in place, fitted correctly and the same thickness both sides. Tyres, especially the bigger 'off road' ones, can bulge if they are slightly under inflated or you are not parked on flat level ground when you measured it.
If all of these are all OK you will need to get the lift kit checked as something might not be fitted or lined up correctly.

The timer hasn't sped up, its the capacitor connected to the motor is running out of charge so the motor will start slowing down and not turn as fast. If you take the back cover off, look for the wires coming out from the motor and there will be usually 4 and 2 attached to a cylinder shaped AAsize battery ( which is what a capacitor basically is) behind a bracket hidden away. Replace it with another capacitor but make sure it's the same charge as the one replacing. There's a number on the front of it followed by mF and that's the size you need. Most dryers run 8 mF but check yours just in case it's not that size. Same thing happens to washing machines with a timer/clock on the display.. Only thing is they seem to go back in time when the brushes are worn
P.S
so it makes more sense why you can't fit a bigger capacitor then the size already there, as you would think a bigger size means more charge so it lasts longer, but no that's not the case. A bigger capacitor will make the motor turn faster which will make it burn itself out

sounds like the starter motor isn't releasing bendix spring ,try hitting starter firmly but carefully a few times, then try starting may get you going ,if does get a new starter.Replacing the battery with a bigger size isn't a good idea what was the difference in amp hour out put ?

good to turn engine,goes by size bigger motor bigger battery,crank power.

Don't put in a bigger size. If it blew once, it means something inside the fan has failed. Take a look for any obvious shorts in the wires: Failing that, Take out the fan, and see if it works. Most likely the short is right at the connector, where it vibrates out the most.

Hi,
If you got Diesel engine you must use a 70 to 80 AmpH battery.
If you got a gasoline engine a normal 60 Amp/Hr bettery can be use.
Hoe that settles that!
Thanks for using Fixya!

NO. You will need to go with a larger motor as you increse the pulley size

Absolutely not. Higher amphour batts don't put out more voltage, just more voltage longer.
The 2800 takes U-1 gel cell batts that run about 33 amphours...good for about 12-16 miles. You might be able to fit bigger batts in it, but measure first before you buy...gel batts are pricey.

Motor Guide hubs come in two different sizes - 3" and 3.5". The 3" size is more for older and lower thrust models. Newer units use the 3.5. The size differences are between manufacturers too. MinnKota's are a little bigger. If you order a new prop, the only issue may be the depth of the prop. I had to use a longer prop nut wrench to tighten the Hydrilla Hacker I purchased.
