i just put cpl picks in my album. kinda hard to get a good pic to show where it is mounted exactly. i just got airmar p66 ducer i need to mount to try to help my 110...yeah i know spending more $ on a lowrance when i should be putting it towards a bird. tell ya what it aint no lie when they say if aint broke dont mess with it. the thing worked fine when i got it with original version than i upgraded so that could network with 337 and share way pnts and data overlay....all F'd up since than.
i know they dont recommend the bow of the ducer being lower than stern of ducer but in my case i figurered that my boat sits stern low so tried to mount it as level as possible while the boat is actually being used for fishing. i took a level with me once and checked levelness while drifting, trolling, searching (10mph) and on plane....it surprised me how low the stern is compared to bow. im just relating ducer setup on boat to how if i tilt my flasher ducer while ice fishing how much different of readings ya get.
bow lift is pretty good with it. what i liked the best was slower on plane speed...im not pushing and causing the bow to be way up in the air while searching with the graph at like 10 to 15 mph. i gained 2mph and 300rpm at top end...54mph/6000rpm. plus at cruising speed of 37mph it lowered my gph from 14-15 to 11. not to mention how it launches out of the hole. i also was running 7/8 tank of fuel. i've got to try a 19 rev4 tho...propman says thats what i need
i think it would work great my self....better patent that i am trying to get some more speed out my 250 so might need that velcro. i tried a buddies high five 21 today and far out performed my 21 tempest...low end and top end and got me closer to the rpm i want of around 6000-6100.....never would of thought that a high five would of helped that much.
i say screw putting that center screw in....it needs to kick up it ya hit something. i even thought wrap velcro around it after ya put the screws through bracket and snap it in place than fasten the velcro around the entire bracket. with the right amount of velcro fastened it should keep from kicking back from high speeds but yet if ya hit something it should tear free.
