    Oil pressure dropping

    Hi Folks, Out on the boat on Monday and noticed that the oil pressure on my starboard engine was falling (per the gauge). It went from a solid 60psi @ 3k rpms to a hair over 40psi @ 3k rpms over a 10 minute period of steady cruising. Temperature and voltage were reading fine, and it was still...

    Persistent Fuel Pump Noise?

    When I bought this boat, 2 years ago, the starboard fuel cell was bad, so I replaced the fuel pumps on both engines for the peace of mind. I don't know if the issue was there before because I couldn't get on plane, but I have always had a persistent high pitched electrical/whining noise above...

    Winter project: 5.0GXi-E --> 5.7GXi-? ECM

    I know August is only this weekend, but I'm starting to plan out my winter projects. I've been going back and forth about upgrading my (270hp) 5.0GXi-E engines with the (320hp) 5.7GXi-? for the extra hp and torque. I'm no stranger to building engines, I've done 4 different V8 Mustangs and Trans...

    Aftermarket Belt?

    Looking to replace the serpentine belt on my VP 5.0 GXi-E (VP p/n is 3586326). Local dealer doesn't have the belt in stock so I was thinking of going to the auto-parts store and getting one today rather than waiting for it to come in. Does anyone know the belt length or have a number I can cross...

    Fuel Pump Electrical Connections

    I'm having issues with the fuel pump electrical connector on my VP 5.0 GXi-E. The metal terminals are loose and not always making a solid connection. I flexed the terminals a bit to tighten them which helped for a while, but now that I know what the problem is, I'd like to fix it once and for...

    Thoughts on trainer/beginner skiis?

    My kids are finally interested to try water skiing after years of prodding. My daughter is 11, around 70lbs and 4' 8" tall. My son is 9, closer to 60lbs and 4' 4" tall. They're both intermediate level downhill snow skiers so I'm not sure if they need trainers, beginner or combo skis. Happy to...

    New gimbal, input shaft and bellows - now it vibrates

    Well, whatever it was that caused the vibration, it's fixed. I took the boat out over the weekend and the more I used it, the less vibration there was. Ended up going WOT for a bit and now, there's no vibration. It's smooth and quiet so I'll take it. I did find out from the mechanic that he...

    New gimbal, input shaft and bellows - now it vibrates

    I had a VP certified mechanic pull my duoprop drive and replace the gimbal, input shaft and bellows. Now, I have a vibration that feels like something is out of balance between 800-1200 rpms and 2000 - 2400. It’s really noticeable and I can feel it through every surface of the boat. My bimini...

    Stalling, limp mode and cranking without starting

    Hi all. New to the forum but long time boater and generally pretty handy. We bought a new to us, 2004 Four Winns Vista 288 this spring and have been slowly going through it. It's super clean and both engines only had 461 hours when we picked it up. We have twin 2004 VP 5.0 GXi-E (3869255) with...
