    Back again, Dealing with the ole pig "iron duke" supposedly they don't die maybe I should put this one out of its misery. I've been through it all different problems different days I've had the old girl for 20 years now still holding on. Last season I noticed a shake at idle. It's almost like a...

    I use the boat all summer every summer could this still be the case? Runs fine now haven't got it in the water but shakes at idle. Fires right up runs normal but just feels like it's shaking maybe a miss?

    i just looked into that rocker more. The push rod for that one is bent. Coulld this be the cause of the issue or a result from bad lifter?

    Okay I will do this as my first steps. When the tick first started I removed the valve cover on the lake and didn't do a very good inspection but tried to do a running adjustment (loosen until it starts to clatter then slowly tighten till clatter goes away, then 3/4 turn more) but it was hard to...

    Do you think I could buy new lifters and change them with the engine still in the boat as a last ditch effort for next season?? I really dont have the time or money right now for a rebuild unfortunately. Put her away in storage this past weekend it might be a long one if i cant figure something out.

    I was able to get a video of it running. Seems to be getting worse. What do you guys think it is? The video with the engine cover off is right after start up. The video with the engine cover on is on the way in after running it for a while.

    Loss of two quarts is my fault there was an oil leak I let go on longer than I should have coming from the valve cover gasket. The two quarts was lost slowly as the oil leaked out after about 8 rides. The oil leak has since been fixed but I neglected to check the oil being in a rush when i fixed...

    The temp gauge still reads a nice 140F when at full operating temp. Can the water pump be bad and still run normal temp?

    Never, at least not since 2007 when the boat was bought into my family.
