Yo SMASH, who told you your boat would get up in 9" of water.....the same kid that had the 10 second mustang in high school? Take a ruler out now and measure up 9", you are just over air boat territory. Your boat like most others of similar design should be able to get up in 14" of water if the bottom is soft. There will be many who disagree with me regarding this post and say that their Majek or similar will get up easily in 9" of water but in all the Majek's and similar that I have ridden in and owned over the past 20 years, can not without extreme difficulty and trench digging. Please don't try to tell me about spinning the boat up, soft bottom, cupped props, trim tabs, water movement thru the tunnel, etc, etc. The good news is that 99% of the time, you can find 14"+ spots of water in a 9" flat.
My 90hp Etec has overheated 3 times in the previous 3 years, because of excessive floating grass accumulation, restricting water flow thru the intake screens.
