Hi guys new to the site,

I'm looking at:
97 Waveventure 760 195hours, needs new battery and has torn seat condition is about 7/10 for $1300 w/trailer. OR
98 Waveventure 700 hours unknown (haven't physically looked at it yet), needs nothing condition looks awesome 9/10 for $1300 w/trailer.

A few questions

Which motor is known to be more reliable?
Top speeds of each?
Any other information would be great.
