    1994 Classic 2252 Fuel/Prop/Consumption Issues-gctid658397

    Hi Guys. Yesterday I helped a bud try out his just bought 1994 2252 classic with 4.3 Mercruiser. He put 65 liters of gas which topped up the tank to 7/8ths full. Off we went but the boat would not get on plane, (his trim tabs did not work which did not help) at 4800 rpm it was doing about 20 knots but it still did not seem to be planing well. Water was flat no wind. My own boat trophy 2052 with same engine is skimming along at 3400rpm doing 20+knots so this is what I am comparing it with.

    So in total about 10 minutes of 4800rpm and the rest about 45mins pottering along at about 5-6 knots at 2000rpm, which I thought was also very slow, my boat will do, I think, 10-12 knots at 2000rpm. Need to confirm that.

    Anyway the boat died after the hour and about 10-12 miles distance. We started the kicker which also died, both fed from the same tank. Fuel gauge reads half full but tank is empty knocking the SS tank sounds very empty and confirmed when friend brought out gas and out of fuel problem resolved. So Gauge or sender needs attention.

    Here is the point. we used at least 65 litres possibly more as there was some gas in the tank before, for the above scenario and the boat seems to be dead slow, which says to me that the prop could be wrong, or is that just how this boat is. since it has a 50 gal tank then the range cannot be much??? Are there any 2252 owners or anyone in the know about this boat with this engine, prop specs would help, consumption figures, etc.

    Any help would be greatly appreciated, the couple who bought the boat are such nice folks, you can imagine their disappointment. all advice appreciated.

    Sorry for long post.

      Could also be a too small prop. Did you still have throttle advancement left at 4800 RPM?

        Yes.We had it up towards 5500 for about 30 seconds or so and the speed picked up to about 25 knots but it still felt like barge at those revs.

          4200-4600 rpm wot is i think your recommended rpm max.

          You have a leaking tank maybe, around 20 years is what Bayliner tanks last ?

          Me i would be pressure testing the tank, in the meanwhile look for fuel in the hull, maybe water also.

          If you find fuel in the hull, remove the battery out of the boat at the moment you find fuel in the hull.
          Be good, be happy, for tomorrow is promised to no man !

            The tank was recently replaced and no fuel leaked into the bilge, first thing I checked, no gas smell anywhere. No water in the bilge.

            Any one know where I can get correct prop specs for this boat and engine?

              Update.

              Discovered that after putting in 40 liters of gas that the tank is full. Gauge reads 90% full and removed sender (to test it) and tank is indeed 90% full so we never ran out of fuel but had a vapor lock so are trying to rectify that. So fuel consumption is not an issue but boat will still not get onto plane so it is still a gearing or prop issue. My bud is emailing Bayliner to find out what the correct specs should be.
