any leads to finding good boat insurance in NY....

i had my baja 240 on my homeowners policy, and when they found out it had more than 240 h.p. they canseled it... now i need to find good ins. for the 33 sonic with 880 h.p..
my agent told me the homeowners policy will not insure boats with more than 10 h.p. per foot...
so any leads would be greatly appreciated

thx
