There are lots of companies. I remember some people last year saying there were only a handfull that were recommended though.
Any help would be great!

After shopping many, many companies last year, I found progressive to be the best price. (boat and 2 pwc) Many insurance companies won't insure pwc, or put the premiums so high it's crazy. (especially if its modded)

I haven't had a claim yet, so cannot comment on service.

Good luck in your search.
