    Volvo penta 5.0 prop issues

    I’d start with looking to see if the sacrificial hub in the prop has spun or sheared, caused by striking the bottom previously. failing that, when she is on the trailer, take the gear linkage inspection access cover off the outdrive and have a look to see if she is going into gear when the...

    What prop do I need? And how do I remove the old one? (Pics attached)

    That’s in the wrong way. No doubt about it.

    Boat Doesn’t Want To Turn Left

    Check the steering is full of oil and not air. Check engine height too. If the engine is too low, it can be hard to over come the effect of prop torque steer, with anything but the best of steering systems like a sea star

    Mercruiser 5.0 TBI

    I might be wrong...but I don’t think un plugging the gear oil sensor would be a way of ruling it out.

    Sorry to ask...but are you pushing in the trigger to engage on the remotes

    At full throttle and it died...

    100% start by changing the distrutor cap and rotor.

    Mercruiser 5.0L MPI 2007

    3 options. 5.0, 5.7 or 6.2 block and change over ancillary items. Issue then is the ecu. I think the 5.0 may have a different ecu and mapping from the other two. Not certain though.

    Is an aluminum steel prop better than stainless?

    I should also add...that I think stainless is always a better option. My previous comments were simple as an answer to the question asked. I also still truly believe that the old fish wives tales of stainless props being a risk of damaging gearboxes and drive trains...are old news. Those takes...

    3 blade SST vrs High five

    The high 5 is doing that because it’s very inefficient at the top end with lots of slip. They usually act like less pitch with the rpms. Only good at one thing. Getting someone pulled out the water with a boat that might usually not have the power to do it...without lots less pitch.

    Is an aluminum steel prop better than stainless?

    I believe a black max ally is better than some stainless props. Yamaha k series props I think are also better than some of them too. Props like a vengeance for example...I think are utterly useless for anything other than being shiny

    Mercruiser 4,3 MPI from 2008, intermittent alarm after 3500 rpm??

    Running cold will cause the oil to remain viscous. Can also damage your engine too. When up to temp and around those rpm. You should likely be around 40-45 psi, I’d think. Should think about getting that thermostat in ASAP.

    Mercruiser 6.2 showing high water pressure

    I think now we know it’s overheated before...I’d be looking to see if there are bits of exhaust flappers stuck down the exhaust and restricting flow.

    Mercruiser 4,3 MPI from 2008, intermittent alarm after 3500 rpm??

    Not sure there would be an alarm for high oil pressure. But that pressure recorded is ridiculously high. What’s the temperature reading at ? If it’s running cold with a full open thermostat, it could be that high perhaps.

    Boat won’t plain starts too then just spins like slipping clutch

    Do you have a vented pvs prop on it...with no plugs in the holes ?

    5.0 gxi-j not starting

    Sounds like the battery to me. Said it loads previously. Very often these will turn over healthy...but will take the power away from the system enough for the thing not to fire up.

    Mercruiser 6.2 showing high water pressure

    Did she overheat previously? Perhaps enough to have a flapper stuck down the exhaust and restricting flow ?

    Intermitent horn alarm in Mercruiser 4.3 MPI

    Iac can cause this. Think it’s a couple of beeps every so often. But need it plugged in really.

    Yamaha VF115 SHO prop quote

    You’re surely on the rpm limiter there. Defo need more pitch. But you won’t know how much, until you’re off the limiter.

    Merc Alpha4 no longer available. What to replace it with?

    Chris. Love this. Am I reading that right to think you are getting 40 knots with the bottom graph ? Probably not reading it right to think you’re getting 1.5 miles per litre at full throttle though, am I ?
