OK, I know this kind of old stuff, but I've been a 911 Nitro owner since 1999. I have a couple of questions about this topic ...
1) Please define a vent kit;
2) What exactly is a pad relief?
I bought my 911 in 1999 new with a 255 EFI Mercury (BLA) and re-propped it with an after market over 27 pitch prop. Although not fast out of the hole, certainly not awful. Top end - 70's. A wondferful fishing platform, a safe, sure ride under 4 foot waves. Trailer is definitely TRASH. Engine: why would anyone put a 225 Mercury on a craft this large is beyond me! Without a doubt, the one thing that would lift this vessel and send it downstream would be a 250 "anything" (except Mercury). The Mercury thing is a personal thing. Any information about #1 or #2 would be greatly appreciated!
