I purchased a 2220 Fisherman and received it just under a month ago. It came with a Mercury Opti-Max 225 Pro-XS/ 20" shaft. The 2220 Fisherman has a 20" transom. I also have a 10" Bob's jack plate on the boat. WOT I can barely trim the motor up before I lose water pressure (max psi 18.1 and is normally around 13.0-13.5 @ 5,200 RPM). I was having some slight cavitation isuues with the boat when I first took it out. Prop was a 3 blade Tempest plus 21P. I sent the boat back to Blazer for that issue along with several other issues (missing extras, scrathes in the gel coat, 3" + crack in the fiberglass on one of the strakes, approx 5' of the keel was scratched and peeling, and a chip the size of a quarter down to the composite material on the right rear corner of the boat), the plastic nut that holds the ignition to the console was stripped, the forgot to send a seat, forgot to install the swim platform, etc, etc, etc. Anyway, blazer took it back and made all of the repairs and ran the boat to check out the cavitation complaint. Keith Craft ran the boat and said there was nothing wrong with it (they also made the other repairs, but the keel repair is starting to peel again) and sent it back with a Revolution 4 23P. I still see the same problems. With the motor @ level trim and the Jack plate all the way down, the cav plate is 5 1/2" above the Keel. My jack plate is mounted at the top of the transom. I talked to a Rep at Bob's and they stated that it should have been mounted in the center of the transom, as it states in the installation manual. I spoke to a Mercury Rep. and they stated that I need a 25" shaft. I spoke to several other people and they all say the same thing. It needs a 25" shaft. I've also talked to some people down in houma that said G&F down in Raceland had this problem with several Blazer's.
Everything on the boat was installed by Blazer. I only ordered extras such as the swim plat, boat cover, etc.
Can anyone give me some input? I'd like to know what I should do and if anyone has had this problem, because I think that I am about to go into battle for a 25" shaft or returning the boat for good.
