    Volvo penta 4.3 gxi-q 2011 poor performance

    I was just going to say that when you have 1 fouled plug, usually an injector issue. Could be oil, but easy to check injector first.

    Engine dumping fuel

    You either have a stuck injector or the ecm is commanding the injector to be on all the time. I would disconnect the injector(s) and try again. If it still does it, it is a bad injector. If not then it is the ecm. The pump continuing to run may be another problem (which may actually also...

    I replaced the water pump impeller and now I have problem with overheating

    If you ran the impellor dry for any length of time (minute or more) it is most likely now damaged. If it had lube on it, it might be okay for a couple minutes. The pump cannot prime itself. In normal use it is below the water line and so is always primed. To test run on land it needs to be...

    RPM issues can't get up to full speed

    Any growth on your hull? Since your engine will wind out to 4K no load mechanically (timing, valves and such) should be ok. Simple (but not always correct) cause would be restriction in fuel delivery. Restricted filter, clogged injectors, etc. Keep in mind you will not produce 65psi fuel...

    Volvo 5.0 glx surging issue

    I am with Senior B on this.... and another clue will be if you high pressure pump is hot. The high pressure pump needs to be moving fuel to cool itself, and when there is no fuel in the tank fed by the low pressure pump it will starve and run hot - just experienced this myself. Oh - and that...

    Starboard side riser temperature creep.

    Somewhere I thought I had read that the thermal switch for the riser temp activates at 210. I had one instance where I had the nipple clogged with an eel (try to figure that one out) - alarm went off and I lifted the hatch to see what was going on - had smoke rising off the riser and manifold...

    Volvo SX-M

    SX-M is your outdrive model, not engine model. Engine model most likely 5.0GXI-something..... Should have a tag on it that states the model number.

    Best aftermarket trim sender

    I bought 2 off of Amazon that had the highest reviews.... they were never quite right and one quit in the first year. So much for the reviews. I have seen OEM's suffer the same fate - hence why I tried no-name ones. I'm either going to try another no name, or implement what my late father...

    Edelbrock 1409 tuning

    yup - 1468 pump will give you a bigger and longer pump shot. Step 1 to eliminate bog. Also - if it has vacuum secondary and you can tighten the spring to delay opening this can help. I normally tighten them to delay them to eliminate bog, then loosen and try them again until the bog shows up...

    4.3 GXI - 2007 blowing hoses off

    I did not think it should have a hose from impeller to circulating pump? I have a 2004 4.3 GXI and the impeller (what I call raw water pump) only feeds thermostat housing. Thermostat housing feeds the circulating pump (hot water comes out of thermostat housing and heads to circulating pump if...

    Broken/Cracked remote filter mount - temp fix?

    Thanks guys for the feedback. I'll be strapping it to the riser and running it till fall. Not sure how I ever overlooked the fact that I cracked it.

    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...
