    Mercrusier 350 MAG MPI - RPM issue under a load

    There is a real good thread right up on bosh injectors. They pertained to 525 type but worth the read. The guy that wrote it oil who I would send you to. He goes by articfriends on offshore only.

    I'm reading the 4.0 SOHC is not a interference engine, so replace the timing belt and drive on

    Mercrusier 350 MAG MPI - RPM issue under a load

    If memory serves yours is a 4B in front and 3B in rear (4x3 Merc XR series). If so your slightly larger then a 18-3x3 standard prop. If its a 4x4 then you could go to 18-3x3 In short you have the smallest pitch props made for the B3 so there is no where to go If its not the ratio, I'm out of...

    7.4 mpi mericruiser cranks over but wont start.

    There is no way any of us can figure out what's wrong without someone actually testing and providing accurate info. Statements like "sluggish, bent prop, fixed prop, " is not working Bent prop back into position, how was that done and balanced so it wouldn't effect the dive from vibration...

    7.4 mpi mericruiser cranks over but wont start.

    Being a 98 it should be cool fuel. The fuel pump should be under the port side motor mount next to oil pan.

    Mercrusier 350 MAG MPI - RPM issue under a load

    If prop pitch is to high for the motor to turn it won't. If you understand a manual transmission, think about trying to climb a steep winding hill starting in high (4th gear in 4 speed trans). It will climb easy in 2nd, but will not be able to in 4th

    Mercrusier 350 MAG MPI - RPM issue under a load

    You have very little time on the plugs so I'm not ready to say somethings wrong. Your not able to get up on plane so there motor is lugging and lots of fuel being burned. Pulling the MAP sensor has the injectors dump more fuel. To much fuel washes plugs and can also wash oil from the cylinder...

    Merc 4.3 in a 2006 Maxum SR3 1800. Will crank, won’t start. Seems to be fuel system related…

    Applying power direct to pump should make it spin. Kind of bad get a new pump and it goes bad after one use The pump should get power from the pur/yel wire on the outboard terminal from the starter. Bypassing the pressure switch should also make it run if the fuse hasn't blown

    Still need the serial number or at least tell us if it has a VST or cool fuel? What is the fuel pressure at the rail? It sound different, might have injected water and would be good to check compression
