    Mercruiser 5.7 won’t make power

    So you originally had the Merc Thunderbolt V on this , didn't get the performance you were expecting and swapped in a Delco EST ( normally both are very good systems). On the Delco EST you are on your third ignition module? I have seen postings here that the aftermarket modules cause issues like...

    Mercruiser 3.0 diagnosis / serial number decode

    Usually mounted on the engine itself small 1/2 qt translucent bottle. I didn't see one in your picture of your engine. Most Gen one drives (88 vintage) do not have one. Just open the drain and then vent plugs, when empty fill from bottom, when full put vent plug back in before removing's lube...

    Computer/Diagnostic/Starting Help Needed for 2000 Kawasaki 1100DI

    I have heard of stators doing funny things like this - maybe you can research how to test the stator and go from there. If you can find a factory manual likely will show how to do so. Likewise sending the EMM out to be checked might be an easy way to rule that out shouldn't cost much or take...

    Computer/Diagnostic/Starting Help Needed for 2000 Kawasaki 1100DI

    Yes especially if all you have to do is reset the throttle position sensor like I did.... unfortunately there is no other way on more modern engines if you need to check fault codes. On my seadoo it looses the throttle position zero point over time so the fuel mapping is off. I was fouling...

    Mercruiser 5.7 won’t make power

    Both the TB and Delco he references using don't have to have a knock sensor disconnected , just need to be put in base mode to set initial timing

    Mercruiser 4.3 EFI Serpentine Belt Replacement

    I don't think it does make a difference buying parts should be 100% interchange. I would strongly urge that for things like water pump impellers and bellows that you use OEM merc items, very common them on this forum that the OEM items last longer. Overall the SEI is a common lower cost (vs OEM...

    Mercruiser 5.7 won’t make power

    Agreed but he also said he replaced the TB ignition with a delco est to no avail so would assume two different systems would not not advance... To OP- might be worth verifying balancer hasn't slipped verify indicated TDC is actually tdc ...

    Engine Misfire!

    Normally a 3.o will have one filter in fuel pump bowl and another in carb inlet. Both are small. You can follow the fuel line back to tank and see if someone added a canister fuel filter to it. If its only happening at WOT probably best to measure fuel pressure at WOT. Could be a plugged fuel...

    Engine Misfire!

    Ok if you just bought it some basic maintenance is likely needed what do spark plugs look like ? agree likely fuel related, would inspect and change fuel filter, clean and rebuild carb, inspect cap and rotor. has water pump impeller engine oil gear lube been changed? Inspect bellows for cracks

    Volvo 4.3 Tinking Sound

    Not if the drive is off. If that video was shot with the drive off I would start with the drive belts on the front take them off run it a short time see if it goes away.

    Sea Rayder F16 Jet Boat

    If wear ring is culprit revs will shoot up but the boat wont go anywhere as impeller is slipping in the water stream vs pushing it through the pump . You didn't mention revs going up, if not likely the engine is the issue. Look up what the compression should be - I think it is 145 or so spec...

    Computer/Diagnostic/Starting Help Needed for 2000 Kawasaki 1100DI

    Cant help much with Kawaski specific trouble shooting but I bought this software package (runs on laptop) for my sea doo works very well. I think with the home model you are limited to 4 Vin numbers being logged in. Sam software as professional just limited on how many skis you can use it on...

    moving trim /tilt motor

    Yes but you need to disconnect the hoses drop them under the engine and reconnect on other side. Would also check you wiring harness can reach. I think unusually they get power off the starter positive lug. You certainly can modify the harness just a lot more work.
