    2004 SX sterndrive new alum prop - slight rub on gearcase housing

    I just installed a new 3 blade aluminum standard rotation VP 3817468 propeller and in the garage am getting a slight rub on the front of the hub against the inside of my SX lower gearcase housing. The rub is just enough that it may for sure remove some paint and may remove some aluminum from the...

    2004 VP 5.0GL-E SX-M 1.6 overheat in lake - not in driveway on garden hose attachment

    Re: 2004 VP 5.0GL-E SX-M 1.6 overheat in lake - not in driveway on garden hose attach Found the problem. I used an electric vacuum pump from work and electrical tape to seal off areas to test the inlet cooling system. I divided things up until I found the section that would not allow any vacuum...

    2004 Glastron GX205SF with VP 5.0GL-E SX-M 1.6. Love this boat!! New boat this earlier year. Bought in Feb and couldn't lake test it. Shame on me! Got it for a fair price.

    VP SX-M lift hook eyelet thread sizing info

    I'm looking to see if anyone would have the thread information on the top oil fill dipstick/plug. This location can be used to insert an eyelet hook to lift the sterndrive unit away from the transom shield. It would save me from having to bring the oil fill dip stick into a hardware store to...

    Recommendation for boat stand for VP I/O lower unit removal and installation

    As the title says, I'm looking for one with casters that I can wheel the lower unit in and out of the gimble bearing housing with the greatest of ease and minimal swear words :) I don't want to make my own in this case as I want a nice piece that works with the VP spacings. Prefer a nice metal...

    VP 5.0GL-E thermostat part number options

    There are two options for this part in the VP store: Thermostat: VP 3587597 seawater kit Thermostat: VP 3831426 freshwater kit Since VP likes to call its impeller drive water pump the "seawater pump", which could draw in either fresh or salt water, the liberal use of this description by VP...

    Is fuel injection a good thing on these VP powered boats?

    Just looking for tribal knowledge is opinions of fuel injection on the marine motors. I'm an electrical engineer and surely understand EFI much better than the carbs. Just haven't worked as much with carbs to fully appreciate the finer aspects of tuning them correctly. I can read a book, but...

    Volvo Penta 3.0GS MWTR troubleshoot: no idle, no power, and black sooty spark plugs

    Been dealing with this now for the last few trips to the lake. Difficult to get on plane, no hole shot power, dies on idle, and plugs end up sooty and black or full of gas. To restart on the lake, I have to take out of gear, and give it 50% throttle and turn it until it starts to catch. It used...

    Method for testing water in fuel?

    Having running troubles with my VP 3.0GS MWTR motor. Dies on idle, power loss, now tending to overheat past the sub 150F normal temp. Plugs 2&3 look black and sooty and plugs 1&4 are wet gas it certainly smells like, so Im guessing its not water. I did have the boat running great the first...

    Fuel-water separator for 1999 3.0 MWTR carbed motor

    I'm looking at the two universal Sierra separator kits that iboats store offers, and the difference is 1/4 and 3/8 fuel line. I looked at my boat and the line only has a red stripe on it, but no markings that say 1/4 or 3/8. I assume it looks like 3/8 but just want to know if anyone has that...

    Volvo Penta SX-M bellows install -need tool?

    I see these tools for Bellows expanders for Mercs, but not for Volvos. Is it neccesary to use these tools on a 1999 Volvo Penta SX-M outdrive to get the bellows back on? U-joint? Exhaust? I'm trying to determine the tools needed to get this job done in my garage. Brent.

    Volvo Penta SX-M bellows inspection on boat?

    Is it possible to just trim up the lower unit and pull the upper drive bellows to inspect the shaft, U-joints and possibly see the gimble area, check for water intrusion, while the lower unit is all still attached? It seems I can see this, but I dont know if there is wisdom that says not to...
