    Volvo Penta SX Prop ID

    I currently have the VP factory 3 blade stainless prop in a 21". I'm cruising Craigslist looking for a 23" 3 blade to see what I can find.

    07 5.0GL WOT Issue

    The way I see it is that you are either getting way too much fuel dumped in or you aren't getting enough. I think I wold check my fuel lines just to be sure they aren't collapsing or blocked first. Maybe even replace them if they are 15 yo factory lines. Have you tried to manually add fuel...

    Volvo Penta SX Prop ID

    So I finally got a chance to run wide open after replacing a bad gimbal bearing and all the accompanying parts. With the new tach I am actually overreving a bit and seeing 48 mph by gps and 5k rpms with just myself and full tank of gas. Once I get a few more bodies on the boat I will report...

    07 5.0GL WOT Issue

    Does the engine sound like it is choking down above 4k rpm?

    Penta 5.7 256 SSX wont start

    I would be cracking fuel lines after the fuel pump and powering the fuel pump to see if you are indeed getting fuel to the injectors. Just my initial thought.

    SX-A, what does a bad gimbal feel like when inspecting?

    Just replaced mine yesterday but my old bearing was absolutely awful. With the alignments tool part the way out it sounded like rocks rolling around in there when rotated.

    1998 VP Cobra SX Gimbal Selection

    I ended up grabbing OEM bellows. The Sierra driveshaft bellows i put on 3 years ago had cracked and thats how the water got in and washed down the gimbal. I always store it with the outdrive down so I'm not sure why it cracked so quickly. Everything is all new and lubed now so hopefully the...

    1998 VP Cobra SX Gimbal Selection

    The outdrive is a 98 Cobra SX powered by a 4.3GL and I need a new gimbal bearing due to a hole in my bellow and water intrusion. I'm uncertain as to what to order though since I don't have an initial on my ID plate. I will attach a picture below so every detail will be included. I'm linking a...

    Water issues

    That top piston looks cleaner than all the rest. If I was a betting man I would say there could have been water intrusion there.

    Yamaha 200etln 2-stroke bad coil?

    Reset all the carbs to factory spec and tuned until coughing through exhaust stopped. Idled great but after I let it sit for an hour and started back up coughing resumed.

    Yamaha 200etln 2-stroke bad coil?

    So I turned opened the mix screw a quarter turn and it is running much better on the muffs with minimal backfires. I'll give it another quarter turn tomorrow and see where that leaves me.

    Yamaha 200etln 2-stroke bad coil?

    This was taken right after the new plugs went in today. Seems much worse when engine is cold. Seems to be a fair bit of soot in the hub too. Starting to think the carbs are over fueling. Rough Cold Idle

    Yamaha 200etln 2-stroke bad coil?

    So it turns out the wire inside the boot end of the coil was corroded. Seems like it still has the same surge in idle though. I'll be changing plugs before the weekend to see if that's my weakpoint before I take it in to have the carbs checked out.

    Yamaha 200etln 2-stroke bad coil?

    Thank you so much for that. I will pull a few coils and bench test them to see what's really going on. This engine sat far too long with no attention from the PO so now it feels like one thing after another.

    Yamaha 200etln 2-stroke bad coil?

    Pretty sure I have a coil going out but wanted to check with yall before I ordered parts. The way I ohm'd these was to attach the negative clamp to the lead going into the coil from the CDI and the positive to the contact in the plug boot. They all read about 2.50k ohms but one came to 6.57m...

    Volvo Penta SX Prop ID

    Thank you so much Scott. The diameter discrepancy had me wondering if this was a VP original. The old tac was a 1998 oem piece that was inconsistent at best so I just put in a new Sierra Lido unit to see where I'm at WOT. It is a little slow out of the hole when I have the boat loaded down but...
