    Remove plastic airbox from front of carbs. Unscrew plug on bottom of each carburetor bowl and see what comes out

    1996 maxum 2400SCR. 5.7L V8 runs

    Is there gas in it? Just because the gauge says so, does not necessarily mean there is, especially on a new to you boat

    Bad compression test on 4 & 6 cylinders

    Simply put, in order for an engine to run you need a process to happen repeatedly. In a 4 stroke engine without getting too complicated, in each cylinder you get suck, squeeze, bang, blow - coordinated with the other cylinders in the engine.

    Bad compression test on 4 & 6 cylinders

    Did you do a bad compression test on cylinders 4 and 6 and are just bragging about it? Did you get a bad report from someone doing a compression test on cylinders 4 and 6? Relative to what? What engine? An in-line 6 would be very different than a V8. How old/how many hours? What are the actual...

    Need help if anyone has advice

    Bite the bullet and pull the motor. There is a crack somewhere and only way you are finding it is a tear down. Especially if the season is short where you live, as long as the other motor that you found checks out, drop that in and then decide if you want to go through rebuilding yours

    Crusader Model RH350 454cu Oil Pressure Sender

    Crusader ran a short hose from the oil port in the block to a t fitting so it could have an oil pressure sender and a second low pressure sender for alarm/light. Make sure you get the correct sender, they look the same but there is one sender for single gauge, and a different sender for dual...

    Crusader Model RH350 454cu Oil Pressure Sender

    You need a second wrench to hold the block that the sender is screwed into while removing the sender

    2008 optimax 115. 22 pin groundfault

    Reservoir under the cowl, correct? I’d then check the wiring between the sensor and ecu before spending on the ecu
