  1. "i'm have plan to remove the kicker motor" Too late 😄 Some days ago, during a strong tropical storm, one of two bildge pumps has stopped and another one was off. The rain start to go inside the boat and the old rear scupper drains allow to the sea water to increase the level in the bildge. Luckily the boat don't sunk ... Now the Robalo still at the dry in the shipyard. I have to replace/check the bidge pumps, seal the aft hatch, replace the scupper drains, partially rebuild the electric system in the battery compartment and, obviously, remove the Yammy 15 (50 kg. less on the transom). I'm thinking also to install an engine bracket and raise the transom.
  2. Hi 2-N-TOW, the color of the gelcoat is dark blue, but, dependig of the sun, change from "eggplant" to light black. The RPM are right; after trying 3 types of propeller, the dealer has installed one 15-3/4x21 SS and run very well. i'm have plan to remove the kicker motor, because now the upper part of the stern is dangerously close to the water.
  3. After a deep check of old engine ... I have repowered and partially rebuilt the 2120 😁 - new engine Suzuki 200 4s - new steering system - new batteries - new fuel lines - new electric system - new bildge pumps - new cockpit - new gps-sounder - new transducers - new vhf - new stereo - new gelcoat Cruising speed 25 knots at 4.600 RPM, WOT 38 knots at 6.700 RPM Pro: fuel consumption about 40% less that the old Yamaha less noise easier start more efficient battery charging Con: due to low transom, it's not possible some maintenance (like oil change) with the boat in the water in case of rough sea, you have to work a lot with the throttle to avoid getting out of the plane about 19.000 US$ less on the bank account 😢
  4. 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.
  5. 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
  6. The 1995 Robalo 2120 user manual is here ... 1995 Robalo .pdf
  7. 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 ....
  8. 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).
  9. Update: - replaced the livewell seacock - commected the livewell seacock to livewell inlet with a Jabsco pump. - cleaned the livewell outlet on the transom (was filled with wood and silicone) - connected the livewell drain to the outlet (without any valve) - used some pieces of PVC pipe is possible to adjust the water eight in the livewell Now the livewell working normally and remain dry when not in use. In reverse too the water don't reach the livewell.
  10. 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 !!! Giorgio
  11. 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 ...
  12. 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 ...
  13. 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.
  14. 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.
  15. 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.
