manifolds ok

I could not remove exhaust manifold drain plugs last fall I drained the water with the hoses at the front of the manifolds,do you guys think the manifolds will be ok?

Tony, If you put regular full strength antifreeze in them to mix with the water trapped in them maybe you'll be ok. If you used the RV antifreeze it being a premix, I really don't know if you would get enough protection unless you poured enough through to purge the water. Still a big maybe! Get the water hooked up to the boat and tell us what you find.

The 3/4" pipe plug can be a big problem. I've got to say a "should have" - If a impact wrench and air compressor isn't available then drill out the center of the drain plugs.

Tim, Would Tony's boat (92) be a down angle trans? Just wondering at what angle the engine is sitting at.

Tony, Were you able to sell the house up north? Sorry to hear it and that you never made it over the dam to see me. Where is the boat?

Tony, It's the internal cracks that can create problem with the water getting back into the engine. Unfortunately the pressure test is the only way to tell if there are intenal problems. You may be ok! In my previous post I did ask Tim if this was a down angle trans (not sure of the year when they started) which would sit the engine level so by removing the hose like you did on the front end would get most of the water out. I'd say give it a try and keep a eye on the oil for any signs of water.

I'm on the south end of Medicine lake. Where's your place? Glad to hear you still have it.

Well I am not Tim but it is very likely a down angle transmission as they started in 89, a very few exceptions are out there with a base 1:1 transmission. I would say there is a better than average chance the manifolds will be fine after pulling the front hose, although in your situation I would have lowered the tongue to the floor to help with the draining.

the boat was on trhe trailer tongue was down so I was able to push it into the garage,if my memeory serves me right I believe the engine is angled toward the rear,will problems be evident right away?

Tony, To be on the safe side, the pressure test isn't a bad idea.

Where are you when not up north?

I'm in a northern suburb of Chicago - Northfield and wish I lived in Three lakes! One of these days I will and the sooner the better.

If you go with the block off plate idea, I would order up a couple sets of gaskets from Skidim. (use the link on our site) 1 set for the test and 1 for the refit. Use them for a template for the 4 holes. I'm sure someone here has the dimensions but you need the gaskets anyway. I understand the riser to manifold gasket to prone to leakage anyway. Get a bolt set at the same time.

Tony, Excellent idea on the schroeder valve! Keep us posted. We'll all cross our fingers.

Tony, Glad to hear the results. Now you don't need to worry about it!
