    How do I get more power out of my engines?-gctid393169

    I have a 2001 Bayliner 3055. Twin 250hp Mercs.

    I had it tuned up and I was thinking that I'd see a noticeable change in power. Is there anything else I can do to increase engine power?

      Ahhh...so put a supercharger on em...at 7k per engine that gets a bit pricey but I like the idea.

        Me- I like turbos instead of superchargers.... up to 1100 HP!

          Real world. The 250s are vortec 2 BBL engines. An easier upgrade would be to get a marine 4 BBL carb and manifold. Probably add 30 HP, however, the low and midrange will increase a lot more than that.

          If you have an alpha drive, its only good for 300 HP. So, ou would need to change the drive, transom plates, and such. it would get real expensive.

          If speed in a cruiser is what you want, trade the boat in on a Fountain.....

          Seriously, just what are you trying to do?

              Lighten up your boat- dejunk it of all unnecessary stuff. You'd be surprised how fast the junk piles up onboard.

              Make sure your hull is clean.

              Other than that, you're looking at Harv's suggestion of a Fountain for speed.....

                Fountain makes (OK made) a 38' Express and a 48' Express. The 48' could be had with triple engines, gas or diesel. That will get you some speed.

                What are you looking for, more top speed? If so a prop change to stainless may help. Looking to get up on plane quicker, a switch to a 4 blade prop may help that, and allow you to stay on plane at lower speeds. Get rid of unnecessary stuff on the boat, make sure the bottom is clean and that will help as well.

                  Generally what has been discussed is what it is. You can add a 4barrel carb that would be easiest. Next re-cam the engines. Reprop. Beyond that its new engines.

                    The ONLY logical thing you can do to improve power on that boat is a manifold and four-barrel carb. I've done it; you gain about 40 HP per engine. I used a good marine manifold and a Holly (650cfm I think) carb. It needed a custom bracket and new fuel lines. However the performance improvement was awesome, and on top of that, I improved MPG by 20%! I have flow meters, so it was easy to see the before and after effects.

                    I'll be doing it to my current boat as soon as I can spare the cash for it. Around $900 per motor once you're all done.

                      I had this bloke make up 2 risers for my engines, and he told me that the stuff he makes improves performance etc. I have no first hand knowledge, however others may have purchased from him, and could add their thoughts.

                      Have just added this, which I noticed on his website as a testimonial, so hope it helps.

                        Hey Wayne

                        Aren't you also running a thread asking how slow you can run the boat at plane ?

                        So you want more power to go slower ?

                        I think you are conflicted in your goals.

                          My wife doesnt like "going fast". I let her know that I'm just trying to stay on plane to maximize fuel economy. Trying to find the happy middle ground what is your slowest planing speed. I believe I can plane at 2900 rpms but I think my stern is digging in a little at that speed.
                          For me, I'd want more power in order to get on step, and then some............. not to just barely stay on step.

                          It's that "then some" that often makes the difference between Poor and/or Good fuel economy.
