Default My first inboard/ need some help!

Hello I just bought my first inboard boat yesterday. It's a 1994 maxum 1800 sr2 with 4.3L that was not running but that part is fixed but with few problems still, the easy one is think the motor not getting right fuel amount some time it run for few sec. Then dies or might run for few min but it's a rough running. The major problem is It makes a loud scweak and pop from what sounds like the back side of the engine and if you put in gear it will grind into gear and pops more and shakes. Any suggestions on what it would be or where to start on the trouble shooting. Thanks for your time and any help I can get

sounds like water in the fuel.

get a gallon can and by pass the tank to test it.

as far as popping and grinding, if in gear is must be the drive is danged.

drain some fluid out of the drive and look for metal shaving or water.

shakes, is not good, so stop testing it until you get that figured out, take the drive off, and run the engine if our of the water to narrow down the issue.

since this is your first boat.....take it to a qualified mechanic....this sounds very serious and from your description..I can't figure out what the heck it could be....

and welcome to the zoo...

Thanks for the fast response guys, I Think I agree with you seapuppy, think I will take it to a marina and have it checked out i am mechanically inclined but the props and all are out of my pay grade. But the popin and grinding is when it is out of gear to just even more intense with it in gear I don't know what's between the engine and the propeler but sounds like it has a knuckle or joint inside that is bad but going take it after work today to shop and have it checked out,didn't think about water in the gas I figured was dead gas or stoped up filter I will keep that in mind.

if your getting alot of noise from between the engine or on the top of the drive...that could be either bad u-joint or bad bull gear on the outdrive.....or even the coupler....a mechanic can best take the drive off and tell you directly....


let us know what you come up with...

It in shop now mechanic checked the lower unit and grease looked good and bearings and gears were fine so says he is about 95% sure its the joints on the out put shaft and the bearing on the shaft locking up, going be a easy fix for little over $200. If all works out I will luck out and gave a good boat for cheap price so got my fingers crossed. I will keep everyone posted on the verdic.

Does anyone happen to know were I can get a marine crank for 94 4.3 lx. I tried to use a automotive crank but it didn't last long so going go back with the right parts.
