    Feedback on Dometic Extreme 3300 cables

    I'm adding a helm on the roof of my 2120 and plan on having T/S cables run from the bottom of the helm through the roof down the cabin side wall and to the cabin controls. To do this will require some tight bends. I'm thinking three bends with a 4" radius bend and one bend that can be an 8"...

    Adding a third hydraulic steering station to a 2120

    I currently have Seastar hydraulic steering in my cabin and second station. I'd like to add a third on a cobia tower on the cabin roof. Can this be done without changing the existing helms? Has anyone done this? Any schematics or direction to articles etc to help with this? Thanks

    Washdown pump causes outboard to lose rpms

    I've had this problem, especially at trolling speeds, when I use the washdown. It causes the outboard to drop in rpms. Usually the only other things using power are two hds gen 3, vhf, point 1 gps, fm radio and occasionally a halo 20+ radar. None of these are affected at all. This is on a...

    Anti siphon valve question

    I think my anti siphon valve is beginning to fail. According to what I've read, the aluminum ones, even 3/8 x 3/8, are for motors up to 200hp and brass ones are for motors over 200 hp. My current one is aluminum, the boat originally had a 150hp on it but now has a 200hp. I've used the...

    Repair sending unit mounting holes

    The screws that mounted the old sending unit to the tank were frozen in these "anchors". I have never seen these before. The holes in the tank, 2004 .125 thickness, are approximately 1/4" in diameter. Should I use a helicoil type insert for the screws, or drill and tap threads in the tank...

    Pitted aluminum window frames.

    Radar Mounting Questions on 2120 scdv

    I just picked up a simrad halo 20+ and want to mount it on the p/h roof. I'm looking for recommendations as to the location, height and angle of the dome. I also have stainless planer board poles about 18" tall on either side of the roof. Would these interfere with the radar beam? How far...

    Wandering 2120 dv Parker

    I am new to Parkers, mine is a 2004 2120 sc with a deep vee, and have read the 2120 ph will ride bow high. My 2120 rides bow high and in anything but a flat sea the boat wanders, especially in a quartering sea. I have a 200hp Optimax (512 lbs.), set second hole down from top which is even...

    Do Parker hulls benefit from barrier coat like Interlux 2000

    I'm new to Parkers with a 2004 2120 that has never had any bottom paint on it. I will be applying bottom paint and was wondering if a barrier coat was necessary. I understand any hull penetrations should be made watertight. Are blisters a problem at all on these hulls? Has anyone on the forum...

    2004 2120 in Md

    I bought a 2120 in December with a bad motor and many things needing attention. Spent the last 4-5 months having a 2004 200hp Optimax hung, new cables, alot of new wiring and just about ready to start the fun stuff, going out on the water. I'm sure I'll have some questions and hope I can add...
