  1. Thank you all for the positive comments! I hope to post some more projects as I have documented everything done on the boat (and everything is done now, finally).
  2. The bilge is separate underneath the tank compartment. On the photo I posted above at 5:56PM you can vaguely see the cover strip for the bilge at the very bottom of the photo. So there is no water that can get there.
  3. My boat is from 1999 and the alu tank was doomed after about 15 years service. The tank compartment is sealed off and dry so the corrosion was from internal condensation building up water over the years on the bottom of the tank (we have coastal climate but snowy winters and hot summers). When we removed the tank it was a mess. I'm so glad I replaced it with polyethylene. There is good reason cars have PE tanks these days, and most new production boats have SS or PE tanks.
  4. Here is the drawing of the new tank I installed (dimensions in millimetres).
  5. I have the Volvo Penta V6-280 EVC from 2018 in my 240 Signature, so same machine as the V6-240 you are contemplating. It is running great and super silent at displacement speeds, but when planing the exhaust note is quite high due to the exhaust is both through prop but also through the plate. The sound is quite sporty though. The torque is there immediately, so very quick acceleration (I have DPS with SS props) and not sensitive about load conditions. The strong point is the easy maintenance, Easy Drain is a fantastic solution to get rid of the sea water and just connect to the garden hose to flush it with fresh water for winterizing (or running the engine on land). The EVC drive by wire system works great and also the servo assisted steering. It's light weight and compact too. All service points are located at the front of the engine, which is great as I can't reach behind the engine in my boat. Only fail I have had these 3 seasons is the oil pressure sensor that I replaced this year, easy enough to do myself (located on the front just under the air filter).
  6. New marine plywood covers the tank, all wood was laminated with glass fibre and epoxy (inside and outside). The fuel line comes from the small hole to the left of the filler hose. I also installed a separate Volvo Penta water-separating fuel filter (part number 877765). The entire engine room was finally painted with 3 coats International Danboline brilliant white.
  7. Last step before reinstalling the aft cabin floor (I reused the same piece that we cut out) connecting filler hose and ventilation hose. The fuel line pickup is located in the aft side of the tank, in the engine room.
  8. With the tank in place I connected the Volvo Penta EVC fuel sender and prepared a fully sealed inspection hatch in the aft cabin floor.
  9. I found a suitable polyethylene tank from Italian manufacturer OSCULATI (part number 52.036.02) 187 litre volume that fit in the original compartment without any modifications. With the new engine Volvo Penta V6-280EVC I reduced fuel consumption by some 20% so the smaller tank volume would not affect the range too much anyway. I was mostly focused on a tank solution that would actually last the complete life span of the boat, and safety.
  10. Installed teak rails for the new tank to get into position.
  11. The tank was in dire condition, several holes.
  12. Tank compartment clean and painted with International Danboline bilge paint.
