Google pump rub & make sure of what you're dealing with first.

If there are other codes, those need to be addressed first. A scan tool will show you current & history misfires for each cylinder to help narrow the diagnosis. Lean mixture problems cause random...

Pull the intake duct off the throttle body. Open the throttle blade with your finger or a screwdriver & look into the intake manifold with a bright flashlight. If it's wet inside, replace the driver...

If it's still missing can you actually feel the misfiring or is it just a code?

I have a 1985 stratos 385v with no power that you can have free if you decide to go that route. Near Grand Haven mi. Would need transom & stringers.

I've posted about this a few times now, but I'll say it again. Pull the air intake tube off the throttle body. Push the throttle plate open with your finger. Look in the intake with a flashlight. If...

Just to be clear, the whole left valve cover needs to be replaced. It's pretty cheap from the dealer.

Like stated earlier, they redesigned the baffle in the cover. The drain plugs up with sludge so the oil gets sucked into the intake. The intake on an ls is dry. If it's wet, it's pulling oil from...

Pull the intake hose off, push the throttle plate open with your finger & look way back in the intake with a bright flashlight. If it's wet, it needs a valve cover.

Pcv valve is not the cause.

You guy's that are burning oil, put a new lh valve cover on it. Has stopped the oil burning on the last 20 or so trucks I have done it on.

They bite hard & run like a 2 inch higher pitch prop from my experience. I have a 23 & a 25. Can't break either loose at Max trim on a 94 procraft 180 pro/175 xri. Pretty decent for the price but I...

I just put the same plate on my 94 180 pro last week. My teleflex cables are 14 feet & fit fine. Mine had a factory jack plate that I replaced.

I think youre going to need a mercury service manual & a dva meter to figure this out. Intermittent problems like this usually arent going to get figured out in the shop unless it's a coomon pattern...

I just ran across this thread & thought id run it back to the top to maybe help some of the guys still driving the older ls powered chevy trucks. I own an auto repair shop in grand rapids michigan &...

Wow! First time Ive ever seen anybody recommend keeping the oil injection system. I started lurking on scream & fly back in the early 2000's when my new to me 2.4 200 blew up. Rebuilt it & eliminated...

Thanks for the thoughts. Since I posted that, I remembered I still have a 200 crank here somewhere that had a good gear on it, so that should solve that problem. I initially was certain I was going...

Hello gents, I joined your boards last fall after I bought a 94 procraft 180 pro with low compression on #6. I pulled the power head & put it on a stand wrapped in plastic a week after i picked it up...
