    2003 Volvo 5.0 GXi-B Changing impeller?

    This Chaparral Signature 240 is new to me, and has about 250 hours on it. It seems like the raw water impeller can be changed fairly easily, but I have no experience with this engine. I have the Volvo impeller kit, and an expoded view diagram I found at www.dougrussell.com from their parts...

    Bennett trim limit or retractor?

    I have very little experience with Bennett trim tabs. What limits the extremes (full up and full down) to keep the hpu from running past the endpoints, if the helm switches are engaged too long? How does the Bennett automatic retractor work? Is it just a timer relay that energizes the retract...

    VP 5.0Gxi tach signal source?

    I have installed a Floscan 7000 on a 2003 VP 5.0Gxi-B. I have the Floscan red switch on position 3 which is for an 8 cylinder engine. However the instructions say that for some EFI engines, the tach signal may come from the CPU and is not always based on the number of cylinders. Does anyone...

    Volvo Penta 5.0Gxi-B: Two fuel pumps or one?

    Reading through the installation package that came with the Floscan 7000-20b-1 device it says that Volvo Penta EFI engines with two fuel pumps will not be able to display the GPH. This is due to the cycling of the low pressure fuel pump when filling the vapor separation module. Does my 2K3...

    Adding flow meter equipment vs. CG approval?

    I just finished reading through the fuel injection thread. Some of you mentioned the lack of CG approval for an otherwise interesting modification. Of course, the safety aspect is undeniable, but it got me to wondering ... I'm planning on installing a Floscan 7000 as soon as the pre-filter...

    Tach question: 2003 5.0Gxi MPI

    I'm about to install a Floscan 7000 on the Chaparral Sig 240. It looks like I can replace the existing tach with the Floscan 7K, and use the wires from the original tach as inputs to the Floscan. If I were to mount the Floscan elsewhere, could I merely parallel the tach wires so that both the...

    2003 Chaparral Sig 240 5.0Gxi Volvo Penta

    I want to install a Floscan 7000 on this boat, and need to know if this engine is a "Closed Loop EFI with CPU Ignition" or an "Open Return EFI with CPU Ignition." How can I tell? I have some info on this engine that says its a multiport fuel injection system, but doesn't say beyond that. Has...

    Installing Lowrance LMS 339iDF in 24' cruiser.

    I have a 2003 Chaparral Signature 240. I'm unsure about where to position the transducers (sounder and speed wheel) on the transom, considering this boat is dry moored. I need to protect them from forklift arms, and also the cradle rack. Does anyone here happen to have a similar situation, and...

    2003 Volvo 5.0 Gxi

    I am interested in purchasing a 2003 Chaparral Signature 240 with 136 hours on it. The seller and I went for a test ride and before the engine had fully warmed up it would cut out around 4000 - 4200 rpm. The problem seemed to go away after the engine had time to fully warm up. The sellers...

    Newbie info please (fuel gals per hour)

    I have a 1991 Bluewater cuddy. It's a 5.0 L/LX with 325 hours on it. For initial testing, I ran it for 2.3 hours at 3000 rpm, with my wife, grand child and myself on board. The 35 gal fuel tank was full and the dry weight of the boat is 3700 lbs. So the weight overall would be about: 400...

    Sierra Fuel Water separator number?

    I need a fuel water separator for a 1991 MCM 5.0 L / LX, serial # 0D520447. The previous owner used a Carquest 86225 filter for this, and I want to use a stock Sierra filter, but the catalog seems to refer to models later than 1992. Can anyone here help me identify the correct Sierra fuel...

    Starting issues - please help.

    For my 1991 Mercruiser 5LX Thunderbolt powered boat I don't have any operators manuals. I would like to know what a 'normal' starting procedure should be. When cold, I have to pump the throttle a number of times while cranking before it starts. The last time out, After a 5 mile run, I shut...

    Attwood surge brake back up lock out ...

    I need to be able to keep the surge brakes locked out during backing. The Attwood surge brake system I have has a lever that can be moved to a detent that allows for this, but when backing up, sometimes it is necessary to move forwards and then continue the back up process. The surge brake...
