    1998 Volvo/OMC - When shifting to forward, the motor stalls. It runs fine on muffs.

    Something it putting an extra load on that engine once there’s water in the Y pipe. Water in the cyls can cause misfires and rough running also, perhaps back pressure is too high, did this engine have the flappers that Volvo later said to remove? If these work loose or melt from an overheat...

    3.0 exhaust manifold over heats

    On the 3.0 cyl head the center cyls have the exhaust valves right next to each other so if the engine is running hot due to typical overheats, overheated exhaust or detonation it will blow the HG between those center cylinders. Ever check to see what temp the ‘stat opens at? Most Volvos and OMCs...

    Pull the spark plugs & see if water comes out the cyls

    I'm wondering if you're getting water in the cyls when launching the boat....

    Installing Bravo3 Sterndrive

    1) I for sure would be using an outdrive jack to install this heavy drive, and start with the bell housing and the drive at the same exact height, try to get the face of the bellhousing straight up and down 2) do not use grease at all on those driveshaft o rings, only use motor oil, if there is...

    1998 Volvo/OMC - When shifting to forward, the motor stalls. It runs fine on muffs.

    Does it stall in reverse as well? Will it shift into gear without stalling when on land running on the water hose? If it's suspected that the outdrive is locking up it could be removed, and water could be fed to the raw water pump to run the engine with the drive removed. A dock line wrapped...

    4.3 v6 Timing suggestion

    I have the same engine, I have thought about upgrading to an electronic distributor but was always concerned about what the advance curve for them would be, given the way they were set up by OMC the advance curve was so ultra conservative. Points are OK on marine engines that don't get a lot of...

    Effect of partial submersion of 5.0 GXI. Effect on Power Steering, Starter, crank sensor.

    Yep that's the one, there are two actually. Lucky you! Even just getting a wrench on the bottom one is tough, I had just enough clearance between it and the Y pipe. Getting the ones that hold the pins for the steering cable and actuator into the steering arm are a pain too, because they are on...

    Effect of partial submersion of 5.0 GXI. Effect on Power Steering, Starter, crank sensor.

    Oh and if Volvo uses cotter pins on those mounting bolts like OMC be prepared for a struggle. They were VERY hard to get out needed a cotter pin extractor, had to remove rear seats & exhaust on both sides to get to it. The cotter pins retaining the pins in the steering arm are also fun to get...

    Effect of partial submersion of 5.0 GXI. Effect on Power Steering, Starter, crank sensor.

    I’d search to see if you can find a parts source and instructional videos. There is also a place I heard of in Fla that can rebuild them depending on which seal is leaking. 5 Starr Marine or something like that. I rebuilt the trim cylinders on my Cobra last year and other than getting the end...

    Lengthening a boat trailer

    I've seen this done a few times, but you have to make sure that the trailer frame is heavy enough to support the weight of the boat and you get proper tongue weight.

    Outdrive service

    yep that's the joint venture cone clutch drive which for all practical purposes is the same as a Volvo SX of the same year.

    Cold engine despite running for a while. Water entering bilge

    With raw water cooled engines it is pretty common to get rust flakes stuck in the thermostat and then the engine will run cool until you get it up on plane. One of the drawbacks to raw water cooling, there will always be more rust, particles, sand, silt in the engine than if you had closed...

    It’s stuck! Might have messed up trying to figure out why it has trouble getting in/out of neutral.

    I could be wrong but I think you have to reinstall the shift lever to be able move the control arms on that style of control....is it a Sea Star? Looks like it might be....Volvo OEM was Sea Star for a while....

    Flushing Sea Ray 250 Sundancer in salt water... How To, and is it necessary?

    If you do a standard oil analysis with Blackstone Labs or similar they will be able to tell you if your engine is wearing well and also if there are any contaminants in the oil like sodium, water, or fuel. With mine there were signs that the head gaskets were starting to leak way before the...

    shine a bright flashlight on the P/S actuator, they often leak.

    Flushing Sea Ray 250 Sundancer in salt water... How To, and is it necessary?

    I have heard this for years. When I pulled my engine apart with 100% salt use guess what? Nothing besides rust! The salt is not the issue it’s calcium. Salt dissolves in water! And, as is common with OMCs & Volvos I ran a 160 stat all those years! I tried a 140 & did not like it; engine took...

    Flushing Sea Ray 250 Sundancer in salt water... How To, and is it necessary?

    I wouldn't worry too much about the flushing, yes do it if you can, but honestly I have never seen any of the inboard boats moored where I am (there is a dock with a hose) get flushed. While I'm sure it helps, saltwater use with a cast iron block gives you at most, 20-25 years at least here with...
