    2120 (1995) repowering

    Hi Rooboy, for now i'm still using the old Yammi 200 2strokes. Last year i had a problem offshore and half boat went underwater. The 2-stroke started regularly (it was almost submerged) and I could save the boat. If I had a 4-stroke, with all the electronics they have, I probably would have gone to the bottom I don't know exactly the size of the propeller, but i'm thinking is the standard 3 blades inox. Anyway, with 2-3 persons on board, the cruising speed is 24 knots at 3800 RPM. Top speed 38 Knots at 5000 RPM. Fuel consumption about 40 liters per hour.

    2120 (1995) repowering

    After several years of happy cruising, it seems that the time has come to replace the old Yamaha F200 2 stroke. Given the high price of the new Yamaha engines, I focused towards the new Suzuki series, especially towards the 4strokes DF175 and DF200A. The seller suggested I choose the DF175, more reliable especially given the low quality of fuel sold in the area. The price difference between the two engines is minimal (around US$ 700). My uncertainty is on the (small) difference in power. I do not pretend to have a missile, but not even a rowing boat. Some of you have already installed similar engines on a Robalo 2120 ? Considering that my fishing trips mainly take place at more than 20 miles from the coast, I also asked if it is not appropriate to change the transom to install 2 outboards (for example 2 x DF90A). Someone has already done this modify ? Thank You. Giorgio Phuket - Thailand

    trim tabs

    I installed on my 2120 a pair of Bennett SL 10 Self-leveling trim tabs, very nice, but useless. My hope was that correct the slight heel of the boat to the port side, however, not only have not solved the problem, but made the boat much more difficult to drive. Maybe with a pair of active trim tabs will be better ....

    Battery Charging

    Problem resolved using a battery combiner instead of diode isolator. You will not need to modify the cable between the battery and the engine. The primary battery (engine) will be charged for first and, when the charge will be complete, the system automatically will start to charge the house battery (services). The red button is for temporary parallel use (30 s.) The system will work when connected to external power to (trough battery charger).

    2120 freshwater tank

    So ... I tried to fill the alleged freshwater tank and, after about 30 liters, was not yet full. The fear is that this water, instead of going in a tank, infiltrate in foam or in some part of the keel. However, the pump has pulled out all (along with a little dirty). Mr. Robalo ... HELP !!!

    2120 livewell drain

    Thank you Parrothead, today i have cleaned the livewell output (inside i find a piece of wood sealed with silicon), The plastic output is in perfect condition. In your boat the livewell output is in the same location and there's any valve near the transom ? Also, inside the livewell tank, the inlet and the drainage are like in the attached pictures ? I think that something was missed ...

    2120 livewell drain

    The output of the livewell has a diameter of about 5/8 inch. It's located just above the seacock of the livewell. Strangely, there is not any gate valve ...

    2120 freshwater tank

    To better understand, these are the pictures of the "load" on the port side and the output to the pump in the aft part of the bilge.

    2120 livewell drain

    On my 2120 (year 1995) the drain of the livewell in connected to one outlet located on the transom, just one inch under the waterline. The previous owner closed the seacock externally with silicone and, perhaps, also took steps to seal the inner side (would seem to be some small holes, but the water is not pumped out. For the moment I have disconnected the hose and the livewell flush in the bilge. Does anyone know what seacock use to restore the system? Thank you for your help.

    2120 freshwater tank

    I'm refurbishing a 2120 (year 1995) and i have installed news bilge and washdown (also used for the livewell) pumps. During this operation i have found a PVC pipe not coming from the middle of the boat and not connected ad all. Blowing into the tube felt bubbling water, but without any leakage of liquid. After some testing, I realized that the gurgle came from a likely tank whose entry load is placed on the port side of the boat, covered by an inspection panel, just below the start of the handrail. Connecting the pipe in question a pump, came out about ten liters of water until complete exhaustion. Someone knows the capacity and the correct use of this tank that does not have a proper load cap ? Thank you for your help.

    1995 Robalo 2120 instrumentation panel

    Thank You, MrRobalo, Year 1995 Serial No. CROA9IRBJ495 My question concerns especially the position of the switches, currently installed in an uncomfortable position behind the instrument panel. I'm going to rewire much of the electrical system and replace various non-functional instruments (tachometer, fuel gauge), so let me know if there are problems to place the switches directly on the console . Thank you again.
  14. I need to restore, possibly like the original, the instrumentation panel and the switch panel of my just bought 2120. I have searched on the net, but i cannot find detailed pictures. Please, somebody con send or link some detailed pictures of the original configuration? Thank You in advance.

    Hi to all. I have just bought an older, but impressive, 2120 with Yamaha 200 2T. I will disturb you because i will need many information about the boat restoration ... The previous owner was probably a farmer :-D I hope you will be indulgent with me
