You should be good with the 8 hp HT. I'll second the Adventure Marine bracket, great product. 25" shaft length is preferrable but 20" works just fine if mounted properly. Although smaller my boat weighs 5-6K rigged for battle. The 9.9 does fine.
Lake Erie perch devour the juvenile zebra/quagga mussels. I have cleaned hundreds of Central Basin perch completely stuffed with them. They graze the lake in roaming schools.
Check out Capt. Mark Chumura's (sp?) online article in an older In-Fisherman about super deep MI kings. The technique translates well to stubborn/grumpy Lake O kings.

I'm replacing power cables on two old cannon riggers. I pulled screws but the cover is still firmly attached. Anyone have some sage advice before I go caveman on the problem?
