    How do these manifolds, risers, elbows look? 1998 5.0Gi's

    Thank you both for the advice. I wasn't sure if they were still cleanable, but I imagine it could be worse inside where I can't see. And to be clear we need all new manifolds, risers, and elbows? The mechanic wants to use Sierra parts, I have read that that is a good brand for the most part...

    Volvo penta 5.0 GI PEPS not going over 3.000 rpm

    Just noticed your thread. We had a similar problem with one of our TBI 5.0Gi motors, it was like a dead spot in the power and we could get past it on occasion and get up to 3000rpm. It first happened when I came off the throttle too quickly, and then wouldn't throttle back up. Mechanic that came...

    How do these manifolds, risers, elbows look? 1998 5.0Gi's

    We suspected we were due for a exhaust service since we purchased the boat at the end of 2019. Engines are open-system ocean-cooled and neither engine ran "hot", we could always place our hand on the riser and hold it there. Taking an temp gun reading showed one riser was a bit hotter, but all...

    About to do my first VP SX outdrive service and have a few questions

    Following the manual makes sense, but it was hard for me to accept not using some type of gasket on our SX-M drive too. If the point is to keep water off of the u-joints then why isn't that better sealed and why does the tube have four grooves in it where it butts against the bellows? It seems...

    Oil sheen in water after start up

    We haven't checked the plugs, we just had both outdrives serviced. It seemed to come from both outdrives/engines, so that leads me to believe it may not be a stuck injector on both engines. Also both engines started and idled very smoothly. We have the mechanic coming to look.

    Volvo Penta 4.3GL and SX Cobra outdrive service manuals

    I plugged in my serial numbers in here and it identified both my VP engines and SX-M outdrives. That is how I found out the -M designation. Your browser might block the search tool, but on the error page I clicked advanced button and click to continue to the page...

    Oil sheen in water after start up

    Thank you for the replies. I am hesitant to think it is any oil from the engines since we only had the outdrives serviced, but I did check the dip sticks and they were not milky. I will recheck the oil level when I return to the boat. It did look a little low on both, but I assumed it hadn't...

    Oil sheen in water after start up

    We have twin 5.0 Gi motors (PBYCCE) and SX-M outdrives, 1998 vintage. We just had a major 'haul out' overhaul on both SX-M outdrives, fully cleaned and serviced, new bellows and gimbal bearings, and U-joints, and seals, gaskets, and lower seals. Then we had them painted with Interlux antifoul...

    Bellows full of grease/oil

    We definitely scratched out head at the 4 indents too. It really seemed like a water intrusion point when we saw them and that our bellows didn't have obvious holes. Even the front lip of the bell has the indents, so if it does seal it is essentially a knife edge seal. Even with some...

    Should we antifoul paint our 1998 SX outdrives?

    Thank you LouC for the very detail explanation. We feel confident that we have a good mechanic, but I know any mechanic could say the last mechanic did something incorrectly. The bellows and gimbals on both outdrives were done in Dec 2018 with all VP parts according to invoice. So I don't...

    Should we antifoul paint our 1998 SX outdrives?

    Well the outdrives are apart now, and while they were fully serviced with new bearings back in 12-2018, it appears to have failed early. There was water in both bellows, and one gimbal (port) bearing was seized to that shaft, and the driveshaft had turned blue from the heat. The bellows seem...

    Should we antifoul paint our 1998 SX outdrives?

    Thank LouC! I also PM'd you on Hull Truth as I knew you'd have something to add. Do you think I should try the BarnacleBusters bellows sleeves too?

    Should we antifoul paint our 1998 SX outdrives?

    Thank you, I was curious since the drives look pretty good if we would just be wasting money and/or just making our bottom cleaner's life easier. I don't think the previous owner ever painted them over 20+ years in salt water, and just had good maintenance on cleaning and zincs. I just found...

    Should we antifoul paint our 1998 SX outdrives?

    We are hauled out now and having the shipyard paint the bottom of the boat. Several people suggested we paint the outdrives for an extra charge. We pay for regular bottom cleaning and the boat was just cleaned before hault out. Boat sits in a salt water slip year round, with sun and tide...

    1998 Twin 5.0Gi SX outdrive Rumble/Growl

    Thank you, I guess that means I need to get it hauled out of the slip and get both outdrives serviced. What else do you think I should have done? I am thinking it makes sense to service the risers and any hard to reach hoses while it is out of the water? Anything else?

    1998 Twin 5.0Gi SX outdrive Rumble/Growl

    It makes the noise while steering, louder when steering to Starboard than to Port. The Port engine is the noisemaker and only when in gear, it runs up to high RPMs smoothly on throttle only (hitting disengage button on throttle). Starboard engine runs smooth in or out of gear, so smooth it is...

    1998 VP 5.0Gi looses power, maybe in protection mode

    UPDATE: Well we think the mechanic fixed it. He just replaced the oil sender mounted off of the filter housing. I assume that is the oil pressure switch @bruceb58 mentioned above. So it does seem possible for that "switch" to have a soft-fail, where it would only trigger EPMode at certain...

    Volvo Penta 5.0 GXI-G Cross Reference List

    Thank you, I also was going to post the hoses and Gates V-belt numbers we found for our 1998 5.0L Gxi's. I should probably do my own thread for my engine, but I'll follow your lead.

    1998 VP 5.0Gi looses power, maybe in protection mode

    It looked pretty "wet" with fuel to me too, but I don't have a lot of experience with EFI in general and I should have looked at the STBD engine to compare. I will report back what the mechanic says tomorrow since we already have him scheduled. I will look into an injector service in the...
