    Question about paint chips in fuel system

    My boat is a 2004, so I have dealt with this - basically changed fuel regulator (3x) and fuel cell. But wouldn't this also effect the injectors?? I do not know much about my injectors, besides being over 20 years old. The engines are 4.3GXI-E. I do not know if these injectors have screens...

    Fuel Line Sources

    I want to replace the fuel lines on my 4.3GXI-E's. They are 20 years old, and I do not know how long they truly last. Is Volvo Penta the only source for these lines?

    4.3GXI-E fuel consumption - resolved

    I will not keep you in suspense, it was fuel pressure. Early in this saga, I did check fuel pressure and injector leak down. Everything looked fine (55psi and no measurable leak down). I am either senile, stupid or this somehow snuck by me. Being a rather recent widower, I would rather be...

    4.3GXI-E Excessive fuel consumption continued....

    Looking for some help with my thinking. I was chasing excess fuel consumption even though engine seems to run fine. Might be a squeak bit rougher idling, but starts fine and runs fine. Here is what I have so far: Ended up using a Techmate to pull data from engines. Boat has twins, so easy...

    4.3 gxi-e "impulse limiter"?

    Can anyone tell me what the "impulse limiter's" function is? It is connected to a hose that goes to top of fuel cell reservoir. Other end goes to intake manifold. It looks like a check valve but it's not called that. I'm out on the water and do not have access to the efi manual. Googling...

    2004 4.3GXI-E running rich

    Just looking for some thoughts before I dig into this - I think I have the basics covered but wanted to double check. I have twin 4.3's and independent gas tank for each engine. Noticed my starboard engine seems to burn more fuel than the port. Also noticed starboard exhaust smells rich...

    Questions about idle speed on 4.3GXI-E on startup

    Been trying to diagnose a hard start condition on 4.3GXI-E. Boat has twins, so easy to compare how they act on start. Port engine starts fine, and revs idle initially then settles back to 600rpm. Starboard engine DOES NOT raise idle at start, and tries to simply start running at 600rpm...

    power steering actuator question

    During my reinstall, I could not get the ram at the end of the steering cable to fit through the bushing/wiper (#11 in picture). I removed the snap ring and removed #11 to ponder what to do, then got interrupted by my neighbor. Later mounted the actuator promising myself never to do this...

    Quick question on steering actuator

    I will be needing to replace/repair my steering actuator soon. Access is very limited. Curious if it can be removed without removing the clevis pin that holds the steering cable. I think it will be very hard for me to reach that cotter pin, and if it is only holding the steering cable I think...

    Broken/Cracked remote filter mount - temp fix?

    Looking for some critique on a temp fix for my remote oil filter mount, 4.3GXI-E. I must have cracked it 2 years ago when I installed new risers/manifolds. I am planning on replacing it, but it is not easy - the bolts cannot be withdrawn since there is no clearance between deck and riser. I...

    Any merits in testing manifold/riser prior to final install??

    So I am a little paranoid about the castings, and worried about major issues I cannot see. Thinking of running water thru them and checking manifold passage for leaks. I think the easiest way to do this is actually with them installed - albeit with the manifold loose on studs instead of being...

    Twin 4.3GXI - now that I have access, what would you change?

    In the process of changing manifolds and risers after 15 years (and signs of moisture in one engines oil and also in the exhaust passage). My boat is a Monterey 282 which has virtually no access to back side of engines. Now that risers and manifolds are off, I can finally access back side of...

    4.3 GXI-E Risers and Manifolds - any newer opinions on GLM?

    Time for me to change risers and manifolds. I have read many negative opinions on GLM, though I got to see a set going on a 5.7 that looked really nice. Has GLM upped the quality level and worth consideration now? I do need the tall risers, so Barr and Osco seem to be out of the conversation...

    Best Crab Cap....

    I need to change the Crab Caps on my 4.3GXI-E, however this will be a major pain since clearance to get to the back of the engines is nill (Monterey 282). Curious what the best cap is.... would not like to do this too often! Thanks for an input or advice you can offer.

    Needing some help with part numbers

    Folks - need a little help with finding an exploded drawing with part numbers for DP-SM transom shield, year is 2004. Cannot find an exploded parts diagram, and have seen on several vendors sites where it states SX transom shield parts are not compatible with a duo-prop. In particular, I want...
