I am not say it does not make it nose dive I am just saying I have not noticed it. The motor I use is from Manncota (sorry can't remember how to spell the company name) and is their salt-water model. I get this type of motor simply because it is suppose to be water tight, even though I do believe the fresh water motors are also water tight. So no problem with my motor and battery getting wet so far. Make sure the battery is a marine battery.
