I am thinking of replacing my 250 Pro xs with a 300 Verado on my 2011 Z9  ? will it be worth the money spend and will I gain MPH ? 

Geez isnt it fast enough! I always get a kick out of these big boats that go 70mph etc how fast is fast? I'd spend the money on tackle etc or GAS you'll need it lol

Hello and Welcome to Bass Resource ~

A re-power is worth the cost if you believe it's worth the cost.

The only opinion that may really matter here belongs to the guy shelling out the $$$$.

Good Luck either way

It'll probably be a little faster, but I wouldn't think it would be by a lot. The 300 Verado is going to be quite a bit heavier than the XS so that's going to negate some of the speed change. Personally I don't think it'd be worth the money. It'll also be over-rated HP wise which means insurance won't cover it. Also, a lot of tournament have a hp limit set at 250. If you're planning on keeping that boat forever then maybe, but if you aren't it could be tougher to sell when you're ready.
