    1994 StarCraft walleye 180

    I have a 1994 StarCraft walleye 180. It’s 18’9” overall length and 7’4” wide. Does anyone know the fuel tank size?

    It has a SS five blade prop but I can’t find any numbers on it.

    About 5200rpm. These are low rpm red line engines.

    1994 mariner 115, oil injection

    Before I ran it I replaced the thermostat and impeller and it’s got lots of cool water coming out the pee hole. No signs of overheating on the head. I ran it for the third time yesterday. Went about 30miles. It pushes the boat nicely so I’m cruising between 3000-4000rpm. 20to30mph. Wot is...

    1994 mariner 115, oil injection

    I was able to get out today and no oil leak. I only tilted up as far as I needed to not all the way and the oil tank is only half full. I marked the tank before I went out and I used 1” of oil which seems about right. I’ll just keep an eye on it. Nice boat ride with the wife.

    Hopefully I can see where the leak is without disconnecting any of the oil system.

    The oil tank is half full no leak while not running and sitting level. I’m taking it out in a few days to see about the oil leak.

    more reading and I’ve found a data sheet that says the oil injection mix changes with rpm. It also shows a check for correct oil amount by running premix. And disconnecting the oil injection and pump oil into a cup to measure. I think I’m going to mark the tank and then fill oil to the mark...

    When I pull the tank out I guess I’ll replace everything I can reach. Like the plastic oil pump gear.

    1994 mariner 115, oil injection

    It doesn’t seem to be leaking from the top. It seems like near the bottom. I’ll have to look into it more. I understand to disable the oil injection has been debated for years. I was wondering more about this specific engine having known problems. I would like to use the oil injection...

    1994 mariner 115, oil injection

    I’m running a 1994 mariner 115 with oil injection and it runs very well. Are these engines getting enough oil from the oil injection? Any known issues with using the oil injection? I do have a small leak of about 1 teaspoon when I tilt it up for a while. I’ll have to pull it apart and fix...
