    Volvo 5.0GXI Overheat/New thermostat

    Take the water inlet hose off the pump- the one that comes up from transom housing , hook a hose up to it a flush backwards to water intake in drive full flow of water should come out. Look for any leakages or reduced flow. Any thing that leaks going backwards likely sucks air. Also could have...

    Is this a concern?

    Depends on the use, my friends 24 ft Crownline deck boat (350mag/300 hp / B3 drive) is underpowered when both our families are in it , touchy to keep on plane. Likely could improve it by swapping Hills props but that's not cheap either. I've owned two boats with the base engine in it, my...

    Wonder if I should go IO again or go OB?

    Muc thanks for the responses here- I think your response for how and where you will use the boat is 100% accurate and biggest factor. I do larger inland lake boating aka skiing and swimming, so having the swim platform an sun pad uncluttered is important to me. My brother has a fishing CC so...

    Volvo 5.0GXI Overheat/New thermostat

    Take out the thermostat and test it in pot of water on the stove. what is the condition of the raw water impeller ? Also i think there is a plastic fitting on the transom housing that the hose bringing water up from the drive attaches to that can break

    Is this a concern?

    Agree pitting shows some electolysis. Grounding or maybe was kept in marina with stray current, easily fixed as said. you didn’t mention what engine is in it. Thats a 23 ft boat with an alpha? May be somewhat underpowered if it is a 5.0. otherwise looks like a clean boat and you dont get much...

    Bellow replacement job

    Did not mean that the remote cable would trip the interrupt switch, just that i was rather surprised when properly set up how little effort it takes to move the lower shift cable vs how much effort to shift at the helm. at any rate we are luckily close to the launch so pulling the boat, fixed...

    Bellow replacement job

    I got it fixed it wasn’t a shift cable. yes I agree normally replace everything but my shift cable I don’t know if it’s newer works perfectly. I did remove it with the bell housing for exactly that reason What it was was the top bushing on the shift shaft that goes through the exhaust passage...

    Bellow replacement job

    I believe it is routed correctly had to do that twice …. It takes more than very very little pressure to shift so I assume something is wrong with cable or work I did to shift mechanism in bellhousing

    Can the base of engine work? Two to bolts under engine are rusted and can

    Back fire is usually timing or fuel related Have you done a compression test and you know the timing and firing order is correct ? If yes to both I would think you have a fuel supply or carburetor issue

    Still no power

    Some tank pick ups have a screen inside them pull the pick up tube and look inside could also be anti siphon valve but as danforth recommended measure fuel pressure at wot If it low tear into fuel supply if it’s ok likely the carb wasn’t done right

    Pooched fuel pump.... need replacement options

    Look up the merc wiring diagram on my boat they run in parallel 12 off the starter when cranking then when in run it comes off the 12v + to coil (purple) through the oil pressure switch to power the fuel pump. If you search these forums you will see threads showing diagrams and commonly...

    Cooling engine - direct water hookup

    Oh if outdrive is off jam the hose in the water passage where drive meets bellhousing. You can cut an old washing machine hose in half fits in pretty good. hold it with a bungee etc this will keep raw water pump lubed up and primed. You can turn the water on before it runs, i usually turn the...

    Cooling engine - direct water hookup

    By bypassing the impeller it you will burn it up unless its not turning ....it needs water supplied to it unless disconnected by removing the drive ( alpha in drive impeller or removing the belt in a bravo set up ) Large hose on right hand side of the thermostat housing is the cold water in...
