I've got a couple of problems with my 98 4.3 mercruiser. I have just finished installing a new motor, don't know if any of these problems have anything to do with that but here goes...
First problem is with the tach... It goes backwards ( counter clockwise) when you rev it up. Don't know how it got like that.
Second problem is no oil pressure reading on the gauge. The gauge never moves or flickers or anything when you crank it. I know its got to have oil pressure, its a new engine!! OR it at least better have, i ain't pulling it back out lol!
Third problem is the trim "up" doesn't work. No clicks or anything. The trim "down" and "trailer" work beautifully.
Fourth problem is that the tilt trim reseivoir has water mixed in with the oil. How did water enter into there??
Also, when you turn the key to on, the position before you crank it, the fuel pump comes on and stays on. I don't remember it doing that before. It could be that i just never noticed it though.
Also, does anyone have a diagram or know which color wires plug into each other on top of the intake( beside the drive oil reseivoir). I think i might have one or two mixed up. I have a black wire with a male spade terminal left over and a white and black wire left over.
There is also a small black wire with a ring terminal on it near the distributor that i don't know where it goes, it appears to be a ground.
The boat has only been run on muffs for 5 mins with the new engine in and i'm just trying to get everything else right before i attempt to break it in sat.
Thanks in advance!!
