4 banger prerunner -ok for a 16-21 ft boat?

that first video got me watching all of the linked vids too. i think op's pre runner would handle this one just fine

That's hilarious. The video with the mexican riding his wave runner into the back of a minivan is great too. Saw that in another thread after searching.

I'll pay close attention to weights and tow ratings and to the condition of the boat launches I plan on using next time I go fishing with my buddies.

 

I'm trying to avoid becoming one of those dumbass "boatniks"

 

boat launches are always a laughing matter. the stuff i've seen over the years are just way to funny. people go out and buy a new toy and have to learn the hard way in many cases. people like to get in someone face and argue. there's a ton of boat launch mishap on utube. truly, the guy in this vid has no clue what he's doing. backing way to far into water and you right, wtf is he doing sitting spinning his tires. he needs to go and sell the jet ski and truck. he clearly does not deserve to be on the road or water. lmao
