    Adding 100+hp. Would you re-prop ?

    Had the boat out most of the day Friday. God I love the 496 big block. What an amazing difference from the 5.7 Mercruiser power I had previously in the 2330. This thing has tons of power with plenty to spare. Jumps on plane quickly and hits 35mph without breaking a sweat. Hammer-down and it goes...

    Weekends in the South end are pretty congested. We try to stay North and above Gainesville Marina.

    Any tuners out there for Volvo Penta ECM's ???

    Already spoke to whipple. They cant tune them either.

    Any tuners out there for Volvo Penta ECM's ???

    I understand this is referred to as the Volvo Penta EGC system... and nobody touches it. How terribly frustrating. I should have bought a boat with Mercruiser power. UGH.

    Mission complete. Came home with a mint, garage-kept 2007 Chaparral 256SSX with a 375hp Volvo Penta 8.1 big block. She really scoots too. Spent much of the week going over minor details and personalizing it. Added a Garmin chartplotter GPS and need to upgrade the sound system. Will probably take...

    Yeah I saw those and it just screams "chinese junk-scam" to me. Not touching that. lol

    Any tuners out there for Volvo Penta ECM's ???

    I have a 2007 VP 8.1Gi in a Chaparral 256SSX. I see Mercruiser tuners and tuning upgrade packages almost everywhere I look... but not a darn thing for Volvo Penta. Can I swap in a Mercruiser ECM ? or is there a company that sells a system to hack/tune the ECM ? (HPTuners)? What are my options...

    Towing a boat with 9ft beam...

    We got home with the boat on Saturday afternoon. Towed it from LOTO Missouri to Dawsonville, GA. 755miles and 12+ hours. I made sure to over-prep for the trip by adding a set of Firestone adjustable airbags in the rear of my Tundra and had several hitch inserts available for correct tongue...

    1999 Chaparral 2130 SS problem

    My Mercruiser 350 in my Chaparral 2330 did not like the smaller CFM carb. It ran its best on the Marine 750cfm Weber that came on it from the factory.

    Just bought a 256SSX. Crisis averted. Picking it up next weekend.

    Towing a boat with 9ft beam...

    Wife and I are shopping for another boat. Looking at 2007-2009 Chaparral 256 and 276SSX's. The 256 is fine @ 102"... but we have found a couple 276's that are similar in price. Unfortunately the 276 has a 9ft beam and I have zero interest in dealing with permit hauling. Wife is wigged-out...

    Adding 100+hp. Would you re-prop ?

    Latest update just to close out this story... Sold the boat and the spare engine about 2 weeks ago. Currently shopping for a 2007-2008 Chaparral 236, 256 or 276ssx with a 496 in it. No more small block stuff for me. Big Blocks only from this point on.

    Adding 100+hp. Would you re-prop ?

    This is a lake only boat... but regardless of that... the next big purchase will be a fully closed cooling system. The engine and manifolds will only get antifreeze run through them. Any water from under the boat (fresh or salt) will only run through the heat exchanger and discharge out the...

    Adding 100+hp. Would you re-prop ?

    If I had known ahead of time the direction I wanted to take this 24' bowrider... I would have opted to build a big block instead. Probably a 496-540 cube combo. There is just no comparison.

    Just got my aluminum manifolds and stainless risers yesterday to mock-up the assembly. Should be a bit of an improvement (and alot less weight) over the stock Mercruiser iron.

    Adding 100+hp. Would you re-prop ?

    Also got better data... I installed a new Garmin GPS a couple weeks ago and on a brief test run... saw that the speedo is WAY off. Last time out... loaded a bit heavy with 75gallons of gas and a 225lb friend. Dash showed 48mph / 4500RPM GPS said I was going exactly 42.0mph. So... I think the...

    Finally got the cylinder heads back from the machine shop yesterday. They have been there since January. Now I can start making some progress.
