Marty you will get the best deal AT the boat show. I am buying a new 115 4 stroke for my 18' aluminum, have been waiting a couple of months now for the boat show as the dealers get extra incentives from the factories. I talked to a couple of dealers I know and they told me to wait. the exception would be if you find a new 2014 that's been sitting around the show room for a while. I'm either buying the etec or the zuke. the new 115 mercs are nice but the price is ridiculous compared to the others. don't overpower or you will have problems with your insurance and will be liable for any damage you do, plus your boat warranty, if you have one, will be void. I certainly wouldn't even consider overpowering a bayliner.
cheers and gl with your purchase.
